Patent ID: 7031431

Claim:
A computer program for controlling a radiological imaging system including a computer executing said program, a radiation source, and a radiation detection unit having a plurality of photoelectric converters arrayed in a matrix-like formation for detecting and converting radiation originated from the radiation source into electrical signals, the program comprising code for performing the following steps: a first reading step of reading the electrical signals output by the radiation detection unit, in which the radiation detection unit is operated with applying the radiation originated from the radiation source; a second reading step of reading the electrical signals output by the radiation detection unit, in which the radiation detection unit is operated without applying the radiation, wherein said second reading step is performed at least twice; an averaging step of avenging the results of said second reading step so as to obtain an average signal value thereof; and a subtraction step of subtracting the average signal value from a signal value obtained at said first reading step.
