Patent ID: 7136452

Claim:
An imaging system for high energy radiation direct conversion scan imaging, comprising: a high energy radiation source member; a semiconductor high energy radiation direct conversion imaging device, including a plurality of individually addressable imaging cells, each imaging cell comprising a detector cell and a readout cell for producing individual imaging cell output values representative of high energy radiation incident on said detector cell, said imaging device comprising an imaging area, having a length and a width comprising plural rows and columns of imaging cells, each extending generally orthogonally to the direction of radiation transmission, and a thickness, extending generally in the direction of radiation transmission, which is substantially shorter than both said length and said width; said source member and/or said imaging device arranged to move substantially continuously relative to an object position for scanning an object at said object position; and wherein said readout cells are arranged to readout said individually addressable imaging cell output values at time intervals substantially corresponding to an object image point traversing half the distance or less of a detector region in the scanning direction during a scan.
