Classification: CPC A  G | IPC G

Claim 11:
12. The apparatus of claim 1, wherein at least one of the plurality of radiation detectors comprises a radiation absorption layer and an electronics layer;
wherein the radiation absorption layer comprises an electrode;
wherein the electronics layer comprises an electronic system;
wherein the electronic system comprises:
a first voltage comparator configured to compare a voltage of the electrode to a first threshold,
a second voltage comparator configured to compare the voltage to a second threshold,
a counter configured to register a number of particles of radiation reaching the radiation absorption layer, and
a controller;
wherein the controller is configured to start a time delay from a time at which the first voltage comparator determines that an absolute value of the voltage equals or exceeds an absolute value of the first threshold;
wherein the controller is configured to activate the second voltage comparator during the time delay;
wherein the controller is configured to cause the number registered by the counter to increase by one, if the second voltage comparator determines that an absolute value of the voltage equals or exceeds an absolute value of the second threshold.
