Long exposures
The maximum duration of any single exposure with waveform data is 300 seconds. The measurement will
continue in "Extra Long Mode" after 300 seconds but no waveform data is available after stopping the
measurement. The maximum duration in this mode is 2.45 days. Note that sessions containing many long
exposures with waveform data may take significant time to save or load data. Modern computers with fast
disc storage and processors will have better performance in this situation. Contact Sales for Radcal's
current tablet display options.
In
, Nugget and Touch WiFi modes all the measurements will continue in "Extra Long Mode".
Nugget and WiFi measurements, however, limit waveform data to 40 seconds.
Pulsed-Fluoro Measurements
Calibration of pulsed-fluoroscopy machines is facilitated through use of the real-time display. When a
fluoroscopy exposure is initiated, the dose rate will be measured and displayed in real-time
need to select a special
Accu-Gold an ideal instrument for tracking dose rate changes as fluoroscopy machine settings such as
mA (current) are continuously adjusted. Previous Radcal products required selection of the pulse rate in
advance in order to obtain accurate real-time measurements. This is no longer required as the Accu-Gold
system automatically identifies individual pulses and pulse rate on the fly providing a stable accurate
reading regardless of kV, pulse rate, and mA.
Combination Measurements
Mammography machines are increasingly supporting multi-mode or combination mode exposures in which
multiple modalities such as 2D, Tomographic 3D, and High Contrast are incorporated in a single exposure
(see above figure). Radcal's Accu-Gold instruments support these modes in a number of ways.
