X-RAY / ENERGY DIFFERENTIATION TYPE 64 CH
GAMMA-RAY CdTe RADIATION LINE SENSOR
DETECTOR C10413
Accomplish X-ray and gamma-ray images with multicolor by energy differentiation
FEATURES
●High radiation detection efficiency due to direct conversion
type semiconductor (CdTe) detector
●Simultaneous energy differentiation of input radiation photons by setting 5 different energy thresholds
●Parallel signal readout from each pixel
●High counting efficiency
●Eliminating effect from beam scattering and hardening by energy differentiation function
●Wide energy measurement range covering X-rays and gamma-rays spectral regions
Application 1: Simultaneous measurement of images at different energy regions
– Energy-differentiated RI* images –
Images were measured by linear scanning over radioisotopes (RI) with the radiation line sensor.
Energy-differentiated imaging allows color visualization and
identification of different radioisotopes.
Images from different radioisotopes can be visualized by energy discrimination for easy color identification.

The output data of this sensor is the
number of radiation photons differented
with five comparators in each detection
element.
The display in color is construction as
for this number of photons.
RADIATION LINE SENSOR OPERATION
Signal pulses from each detector pixel are differentiated by the five comparators according to their energy levels. These signal
pulses are then counted by the five counters and output as the number of photon counting pulses.

Application 3: Eliminating effect from beam scattering and hardening
Images obtained without energy
differentiation are subject to effects
from scattered rays and beam
hardening. These scattered rays
and beam hardening can be eliminated by setting the proper energy
differentiation levels.
