In contrast, Sensus Healthcare's SRT-100(TM) and SRT-100 Vision(TM) use kilovoltage X-rays in the 50 to 100 kilo volts (KV) energy range.
General technical ALARA strategies to reduce exposure include: 1) weight-based protocols for radiation parameters (eg, kilovoltage, kV; milliamperage, mAs); and, 2) body and selective organ protective shielding.

The characterisation was performed by doing entrance exposure measurements using the manual technique, fixing the kilovoltage and varying the mAs, and then repeating the procedure for a series of kilovoltages: 23, 25, 26, 28, 30, 32 and 34 kVp.
