AEC-6 System
Model 07-AEC6
- May be used to calibrate/adjust AEC systems without film
- May be used for performance assessment of mammo/radiographic
AEC systems without film
- Can be calibrated to the local screen film/processing conditions
Introduction
The AEC-6 System, consisting of an electronic screen-film cassette, an electronic interface box, and a Palm Pilot (or computer software), can assess the performance and calibration of mammo/radiographic AEC systems and can provide information to estimate the relative speed and gradient of screen-film and processing systems. Once the AEC-6 meter is calibrated to the screen-film characteristics and processing conditions, the meter provides the user with a readout in optical density for each exposure made.
Applications
Service engineers use the AEC-6 meter to calibrate and make adjustments to mammo/radiographic AEC systems instead of using film. Medical Physicists use the AEC-6 for performance assessment of mammo/radiographic AEC systems and based on the assessment, make recommendations for corrective action. Radiation inspection officers use the AEC-6 to assess mammo/radiographic calibration and suggest corrective action to x-ray equipment operators. Technologists use the AEC-6 meter for teaching and routine quality control evaluation and balancing optical density from room to room.
Features
The electronic cassettes, once calibrated, mimic the screen-film systems used in a radiology department. Each electronic cassette contains circuitry that analyzes the light output from the intensifying screen(s) and converts the light into a digital electrical signal which is fed to an onboard microprocessor for analysis. The microprocessor sends information via the interface box to a Personal Data Assistant, PDA (Palm Pilot) or computer for software analysis using mathematical algorithms that converts the microprocessor information to optical density readouts.
Specifications
AEC-6 SystemAccuracy Optical Density (OD) prediction ± 0.1 OD ranging from 0.5 to 3.0
Dynamic range 0.2 to 4.0 OD
Setup and reset Manually using PDA or computer keys
Controls Manually using PDA or computer keys
Functions OD, Time, AEC#
Power requirements 2 externally-accessible 9 V batteries (Duracell MN 1604 or equivalent)
Typical battery life > 40 hr
Operating environment 59° to 95°F (15° to 35°C)
Electronic cassettes
The electronic cassettes (mammography and radiography) simulate the film-screen cassette used in the radiology department and provide digital electrical signals to the PDA or computer.
The mammographic cassette is specifically designed to mimic the attenuation of the film-screen cassette. An accessible compartment (drawer) allows various thicknesses of aluminum to be placed in the cassette to match the attenuation of the film-screen cassette.
