CIRS ATOM® Dosimetry Verification Phantoms

CIRS ATOM® Dosimetry Verification Phantoms
Features:

CIRS ATOM® phantoms are a full line of anthropomorphic, cross sectional dosimetry phantoms designed to investigate organ dose, whole body effective dose as well as verification of delivery of therapeutic radiation doses.

ATOM is the only line of dosimetry phantoms to range in sizes from newborn to adult. Six models are available: newborn, 1-year, 5-year and 10-year old pediatric phantoms as well as adult male and female phantoms.

Each phantom is sectional in design with traditional 25 mm thick sections. The sectional surfaces are extremely flat and smooth and do not require any special coatings or treatment. This results in minimal interfaces between the slabs when viewed in a scout or projection X-ray. The ATOM line also differs from other dosimetry phantoms by providing optimized TLD locations specific to 22 inner organs.

Tissue-equivalent epoxy resins are used in all aspects of the phantom. CIRS technology offers superior tissue simulation by covering a wider range of energy levels from diagnostic to therapeutic. In addition, all bones are homogeneous and are formulated to represent age appropriate, average bone composition. CIRS bone formulations offer distinct advantages over natural skeletons and other types of simulated bone.

The Choice for Quality Assurance, Clinical and Research Applications

ATOM phantoms provide our best tissue simulation and the widest variety of options available on whole body cross sectional dosimetry phantoms. Additionally they are designed to accommodate a wide variety of detectors in a variety of configurations offering dose measurements in precise body locations.

Anthropomorphic Phantoms From Adults to Infants

DOSE CALCULATIONS RELATED TO SIZE

The size of each model is based on ICRP 23, ICRU 48 and available anatomical references (See Table 1). Only CIRS ATOM phantoms represent both pediatric and adult patient groups.

This age range allows more accurate calculations of dose. The pediatric products support practitioners efforts to "child size" diagnostic scanning protocols in CT and more precisely determine effective doses in diagnostic radiology. Because scattering radiation can give a significant dose contribution to the surrounding tissue, the ATOM newborn and 1-year old are provided with arms and legs as a standard configuration. Arms and legs for most ATOM models can be ordered separately (see page 10).

Note: ATOM Fat Layers, Model 701-12, can be used with Adult Male ATOM Phantoms to represent bariatric or pregnant patients. See page 11.

BONE SIMULATION APPROPRIATE TO AGE

Bone density varies significantly with age. This is especially significant in the pediatric models because the red bone marrow is distributed throughout the skeletal systems compared with adults. Proper bone simulation is also important for a pediatric patient because they have a higher sensitivity to the effects of radiation. Therefore, for more precise dosimetry measurements, ATOM phantoms are formulated with bone equivalent materials based on the appropriate bone composition typical of each age.

Proven Tissue Equivalent Technology

CIRS tissue simulation technology has been validated through specific testing, continuous monitoring of manufacturing applications, worldwide use and acceptance of products for over 25 years.

CIRS formulates Tissue Equivalent (TE) materials for quantitative measurement, training, image quality control and dose calibration. Resins and polymers are available to simulate any tissue in the human body. CIRS computer models consider tissue to be mimicked, modality/energy level and raw materials to be used.

ATOM phantoms are constructed of CIRS proprietary tissue equivalent materials. Linear attenuations of the simulated tissues are within 1% of actual attenuation for soft tissue and bone and within 3% for lung from 50 keV to 15 MeV. Lung tissue in each phantom is made standard with a low density inhale formulation equivalent to 0.2 g/cc. Other densities are available by special order.

The tissues simulated in ATOM phantoms are average soft tissue, average bone tissue, cartilage, spinal cord, spinal disks, lung, brain and sinus. Simulated bone tissue for pediatric models matches age related density (Reference Table 2).

Homogeneous Bone

The skeletal anatomy of ATOM phantoms includes a homogeneous bone tissue composition that averages known cortical to trabecular ratios and age based mineral densities. Bone tissue compositions for the adult and pediatric phantoms were designed based on the most reliable data available. There are many advantages to using average bone rather than natural skeletons or simulated skeletons that include separate trabecular and cortical densities. *This design feature provides for dose verification in different applications, especially when comparative Monte-Carlo calculations are necessary.

For inner organ dosimetry the bones usually play a shielding role and can be simulated using an average bone because their inner structure is not critical. For the purpose of red marrow dosimetry, it is important to make measurements in electron equilibrium, which is easier to obtain in a homogeneous average bone of known density than in an unknown ratio of cortical to trabecular bone material. Further, the size of actual dosimeters is typically larger than the trabecular structure leading to imprecise measured trabecular dose. As a result an average bone substitute is often preferred for simulation except in very unique cases and for reasons of image aesthetics.

Benefits of Homogeneous Bone
LIFE-LIKE IMAGING CHARACTERISTICS

Because CIRS materials are epoxy based they can be machined to achieve optimal flatness. They also do not require surface treatment or coating thus the air interface between sections is minimized.

Even the phantom holder has been designed to optimize ATOM imaging characteristics. Each phantom comes standard with a unique holding apparatus that consists of a top and bottom compression plate that is adjusted with the included wrench. The plates are joined with four thin Teflon wires that are radiographically opaque. There are no solid rods running through the phantom body to interfere with the imaging characteristics. Instead, the top of each section has a small tab which fits into the corresponding indentation on the underside of the preceding section.

Optimized Organ Dosimetry

CT and Cone Beam CT dosimetry can require organ dosimetry and whole body dosimetry. CIRS is the only manufacturer that offers organ hole locations specific to 22 radiosensitive internal organs, optimized for precise calculations using the minimum number of detectors necessary. The selection of hole positions is supported by detailed anatomical information about the average position of these 22 radiosensitive internal organs. A set of maps outlining the most frequently observed organ locations and also the optimized detector hole distribution within each organ accompanies each phantom with "-D" configuration. This map book shows the hypothetical outline of the internal organs appropriate for each section.

CIRS ATOM® 072-D Organ Dosimetry Option

The holes that are drilled into each section are also shown on the map along with the corresponding unique hole ID number. The map is used in conjunction with a lookup table that indicates, for each organ, the number of detectors to insert, the hole number for each inserted detector and the corresponding detector depth for each hole. This assists the dosimetrist in minimizing the quantity of detectors utilized. In this regard it is important to note that the precision of an average organ dose calculation is dependent upon the precision of the detector method. The "organ placement" feature eliminates estimating detector placement and is supported by extensive anatomical and dosimetric research.

Dosimetry Holes in Standard Grid Patterns


CIRS ATOM® 072-B 702-C Grid Option

Dose verification in Radiation Therapy can require standard 3cm X 3cm (option "-B") or 1.5cm X 1.5cm (option "-C") hole grids. These are available in lieu of the organ placement feature.

For all hole options, the thru holes are typically 5 mm diameter. Thru holes of 3mm, 7mm and 10mm diameter are available as standard options. Other hole sizes may be available via custom order.

Detector Options

CIRS ATOM® 072-B 702-C Grid Option

For all grid options, holes are filled with 5mm diameter X 25 mm long, solid plugs of corresponding tissue (soft tissue, bone, cartilage, spinal cord, lung and brain). Extra plugs of each tissue are also provided with every unit. Plugs specifically machined for TLD chips, TLD rods, TLD bars, TLD cubes, MOSFET detectors, and Landauer OSL Micro Dot and nanoDot holders are also available as optional accessories.

THERMOLUMINESCENCE DOSIMETRY (TLD)

CIRS ATOM® Standard Solid TE Plugs, TLD and Chip Rod Holders

Sectioned and drilled phantoms readily accept TLDs. The end user can cut the tissue equivalent solid plugs so the TLD can be sandwiched between the cut plug and positioned at the appropriate depth within each section. This is especially critical in organ dosimetry and is supported with a table indicating at what depth to place each detector within the sections corresponding to the organ of interest.

Tissue equivalent plugs cast to precisely receive TLD chips, rods, bars and cubes are an available accessory. These rods are available in brain, bone, lung and soft tissue formulations and can be cut to length by the end-user in order to position the TLD at the appropriate depth within the section. TLD disks use the standard TE plug provided with the phantom.

MOSFET DOSIMETRY

CIRS ATOM® MOSFET Cartridge

CIRS ATOM® cable on slab

MOSFETs are accommodated by ordering the ATOM MOSFET Cartridge as an accessory. This specially machined plug is available in soft tissue and bone formulations. The plug has a recessed area that fits the MOSFET detector along the side of the plug while still allowing the plug to fit into the 5 mm diameter hole within the section. A radius on the end of the cartridge allows a 90 degree bend in the cable. Black tape (included) can be placed on either side of the cable on the slab to prevent damage to the cable when the phantom is assembled.

FILM

CIRS ATOM® cable on slab

Film dosimetry is supported by ATOM dosimetry phantoms. Both radiographic and radiochromic film may be placed between any two contiguous sections. The sections are then sealed with the black tape provided to prevent any exposure of the film to light.

NANODOT DOSIMETRY

CIRS ATOM® Nanodot Dosimetry

Landauer OSL nanoDot holders can be utilized with the ATOM phantoms. These dosimeters require 14mm diameter drilled thru holes and plugs configured to receive the holder. This option is only available with the organ dosimetry option and is not available with all models.

ION CHAMBERS AND DIODES

CIRS ATOM® Ion Chambers and Diodes

ATOM phantoms can be drilled to accommodate various ion chambers and diodes. The Chamber cavity is drilled in the lateral direction along the mid-plane of the section. Customers should specify desired location of isocenter. Each chamber cavity is supplied with a soft tissue-equivalent plug.

Breast Attachments

Breast Attachments are an optional accessory for the Adult ATOM male and female phantoms only. ATOM phantoms do not come configured with breast attachments. All breast attachments are manufactured from 50% glandular/50% adipose equivalent material (BR50/50). They are available in two shapes: standard shape (representative of a patient in the upright position) or with supine shape. Each shape may have a range of available sizes. Customer must indicate if right or left side attachment is desired.

FEMALE BREAST ATTACHMENTS

CIRS ATOM® Female Breast Attachments 702-BR-190 & -350

The Model 702 Adult ATOM Female does not include breast attachments. 190 cc and 350 cc standard shaped breast attachments are available as an optional accessory. These attachments will be provided drilled with 5mm diameter thru holes in a 2cm X 2cm grid pattern.

MALE BREAST ATTACHMENTS

CIRS ATOM® Male Breast Attachments 701-BR-350

The Model 701 Adult ATOM Male can also represent a larger female patient than the Model 702. For this reason, breast attachments are available for use with the Model 701.

One standard shaped size, 350cc, is available and is provided drilled with 5mm diameter thru holes in a 2cm X 2cm grid pattern.

CIRS ATOM® Small Single Supine Breast Attachment 400cc 701-BR-01

CIRS ATOM® Medium Single Supine Breast Attachment 800cc 701-BR-02

CIRS ATOM® Large Single Supine Breast Attachment 1200cc 701-BR-03

Supine breasts are available in three sizes: small (400cc B-C cup), medium (800cc D cup) and large (1200cc DD cup). They represent the clinically relevant geometry of a patient laying on her back. Supine breasts are typically used for compensation and are not drilled with any hole pattern.

Arm & Leg Attachments

Certain studies may require the use of arm and leg attachments. This may be of particular importance during environmental studies and in the analysis of radiation protection in an industrial setting.

Because scattering radiation can give a significant dose contribution to the surrounding tissue, the ATOM newborn and 1-year old are provided with arms and legs as a standard configuration. For all other models, arm and leg attachments are available as an optional accessory. This option includes both right and left arms and legs. Limited dosimetry configurations are available and presented on page 13.

In case of A, B, D and G configurations, arms are provided with a single sagittal slice along the mid-line. However, legs are sliced axially in 25 mm thick continguous sections.

CIRS ATOM® Arms and Leg Attachments

ATOM Fat Layers

Imaging and diagnosis of bariatric patients presents unique challenges. Improper scanning parameters can result in missed diagnosis, equipment failure, or increased radiation dose to patients and staff. To more appropriately assess image quality and dosimetric values for these patients, optional ATOM Fat Layers can be applied to Adult Male ATOM phantoms. Fat layers mimic human tissue within 2% by linear attenuation for MV and KV energies and are suitable for CT imaging with Wide Bore and Cone Beam CT scanners. Model 701-12 includes a set of two 4 cm thick layers, which may be used together or separately.

ATOM Fat Layers

Most ATOM Phantoms include the top of the head through the mid-thigh. Adult ATOM male and female phantoms (Model 701 and 702) are made in three parts: head with c-spine, thorax and pelvis. Therefore, these two models are available as complete or partial phantoms.

Standard configurations include solid non-sectioned parts without dosimetry holes or axially sliced, 25mm thick, contiguous sections. Sectional phantoms are available without dosimetry holes or thru drilled with 5mm diameter holes. For drilled sectional phantoms, there is a choice of three different hole grid patterns 3cm X 3cm grid spacing, 1.5cm X 1.5cm grid spacing or Organ Dosimetry spacing.

The Newborn and one-year old (Model 703 and 704) are only available in 25 mm sections and include both arms and legs. An optional set of arm and leg attachments is available for all other models (see Optional Accessories table on page 13 for part number).

SPECIAL REQUESTS

Although most dosimeters can utilize the 5mm diameter thru holes, there are those detectors that cannot. CIRS offers thru drilled holes of 3mm, 7mm,10mm and 14mm diameters upon request and at no additional charge. Additional diameters may be available via custom order.

ATOM phantoms are available with a wide variety of standard grid patterns, hole sizes and additional accessories. As each ATOM is made to order, phantom configuration must be indicated at the time of order. Not all configurations and options are available with every model. Please contact Supertech for configuration and ordering assistance.
