Method and system for sensor array readout having reduced crosstalk

摘要

A system includes a sensor array (22) with scan lines (32), data lines (34), and, for each cell (30), a sensing element (40) and a switching element (44). Each sensing element includes a charge collection electrode (42). The sensing elements are stimulated during an interval in which data lines are electrically connected to a fixed potential, reducing induced charge and crosstalk. The stimulation (56) could, for example, be x-ray radiation. Then, during a following interval, a scan signal has a duty interval after which signals are read out from the data lines. During stimulation, the data lines can be connected to ground or can be connected to virtual ground by resetting their sense amplifiers.
