Abstract

A high resolution flat panel for radiation imaging includes an array of pixels arranged in rows and columns. Gate lines interconnect the pixels of the rows while source lines interconnect the pixels of the columns. Gate driver circuits provide gate pulses to the gate lines in succession in response to input from a control circuit to select the pixels on a row-by-row basis. The source lines lead to charge amplifiers for sensing the signal charges stored by the pixels when the pixels are selected. At least one pair of adjacent pixels in each row of the array shares a source line. Gating of the pairs of pixels in the rows that share a source line is controlled by control logic to ensure that signal charges stored by only one of those pixels is applied to a shared source line at a time. This allows the number of charge amplifiers in the flat panel to be reduced while maintaining high resolution.
