QA Mamchex Tool - for CARESTREAM DIRECTVIEW CR Mammography
Product Description:
The QA MAMCHEX Tool - for CARESTREAM DIRECTVIEW CR Mammography is a factory X-ray calibrated NIST/PTB traceable meter that can be used instead of a dosimeter to assess and calibrate the automatic exposure control (AEC) sensitivity and density control settings.
Technical Specifications:
The QA MAMCHEX has the same energy response to X-rays as a Mammo CR imaging plate (X-ray-to-light conversion), and displays an accurate and precise value for the light produced by the plate when exposed to X-rays (MamLU--Mammographic Light Units: which is directly proportional to the light produced by the CR imaging plate when scanned by laser light in the plate reader).

The QA Mamchex is the only device of its kind and is available exclusively from DISC!
This QA MAMCHEX Tool - for CARESTREAM DIRECTVIEW CR Mammography device is designed to work with CARESTREAM DIRECTVIEW CR Mammography Systems.
X-ray energy dependence: Simulates relative light output of Photostimulable Phosphor Plate (PSP) within +/- 5% over kVp range of 20kVp to 32 kVp and a patient equivalent thickness range of 2 cm to 8cm (within specified operating rates).
Digital Range: Mammo Light Units(MamLU); MamLU: 0 to 6553.5
Minimum MamLU Rate: 15.0/Sec (approx. 1.5 mR/Sec cassette entrance exposure rate)
Maximum MamLU Rate: 3000/Sec (approx. 300 mR/Sec cassette entrance exposure rate)
Power On/Off: Manual Switch
Power requirements: Built in NiMH rechargeable battery pack (9.6V)
Operating environment: 15°C to 35°C (59°F to 95°F)
Electronic Cassette Dimensions: Fits 18 x 24 cm Bucky; Fits 24 x 30 cm Bucky with L adaptor
Electronic Cassette Weight: 1.8kg (3.9 lb);L adaptor 0.73kg (1.6lb)
Demo Instructions:
Nothing could be easier. Turn on the QA MAMCHEX electronic cassette andplace in the Bucky or table-top and make an exposure. The self-contained display in the cassette will register three values; Optical Density (OD); Mammo Light Units (MamLU); and radiation exposure time (sec). Comparison to benchmark values can be performed to confirm the integrity of the X-ray tube and calibration of AEC. The QA MAMCHEX can be used in place of the CR mammography cassette and CR mammography system to perform lengthy AEC calibrations and/or assessments. The QA MAMCHEX can deliver an eight-fold improvement in productivity over conventional calibration techniques.
Primary End Benefit:
Since the meter has the same energy response to x-rays as the CR mammography cassette, the meter can take the place of the CR mammography cassette and CR mammography systemwhen assessing the AEC system performance for thickness and kVp ‘tracking’ and density selector settings providing a tremendous (eight-fold) boost in productivity and hence, cost savings! The meter can be used by the technologist for QA or by service and biomedical engineers to calibrate the AEC, troubleshoot the X-ray tube, AEC, and density selector settings.
