Sensors - Radcal Accu Series User Manual

Sensors

The Accu-Pro™ control unit can connect to various sensors to provide dose and x-ray beam information.
The three main classes of sensors are the Accu-kV sensors that determine x-ray beam characteristics,
the ion chambers that measure radiation dose and the diode-based radiation sensors. Also available are
mA sensors used to determine x-ray anode current.
KV sensors
The Accu-kV sensors use differential absorbers and photodiodes to determine kV. You can select the
filtration to be used for kV calculations in Setup. Automatic filtration correction is available for the
diagnostic sensors. Both mammographic and diagnostic sensors are available that can accept a dose
diode input for observing radiation waveforms and to provide dose measurements synchronized to with
the kV pulse.
Diagnostic sensors are black; mammographic ones are purple.
40X9-M - Basic mammographic Accu-kV sensor.
40X10-M - Same as 40X9-M with provision for DDX-10M diode sensor to observe radiation
waveform using oscilloscope or XLPRO. (Discontinued - see below)
40X9-W - Basic diagnostic Accu-kV sensor. (Discontinued - see below)
40X10-W - Same as 40X9-W with provision for DDX-10W diode sensor to observe radiation
waveform using an oscilloscope or XLPRO (Discontinued - see below)
40X11-W - Same as 40X9-W with provision for DDX-10W and automatic filtration compensation.
(Discontinued - see below)
40X12-W - Same as 40X9-W with automatic filtration compensation.
The Diagnostic range sensor accuracy is ± 1 kV or ± 1 % whichever is largest. The mam mo sensor has an Mo-Mo
accuracy of ± 0.5 kV and < ± 1 kV for other track-filters.
40X12-W Accu-kV
The sensor for Diagnostic range (40 kV to 160 kV) measurements
Besides kVp, also measures, displays, and compensates for beam hardness (add ± 1 % when
on). Inherently correctly reads AMX4+ and AMX 700 portables. Flash HVL: ± 0.3 mm Al and ±
10 % of reading, 1-23 mm total equivalent thickness Al, 40-160 kVp.
40X9-Mo Accu-kV
The sensor for Mammographic range measurements
This versatile sensor is designed for 0.5 kV accuracy for Mo-Mo mammographic beams. It may
also be used at < ± 1 kV accuracy for Tungsten-Silver / Rhodium tubes on Hologic Selenia
mammography machines.
Recommended for starter kit configuration.
