Method and apparatus for triggering image acquisition in radiography
First Claim
1. A method comprising:
- charging an interconnect with a switch in response to radiation incident upon the switch while the switch is in an open-circuit state, wherein the switch is coupled between the interconnect and a detector;
monitoring charge on the interconnect; and
generating a signal indicating presence of the radiation in response to the charge on the interconnect.

Abstract
An apparatus for triggering image acquisition in radiography includes an interconnect, a detector to detect radiation and a switch coupled between the interconnect and the detector to charge the interconnect in response to the radiation while the switch is in an open-circuit state. The apparatus also includes control circuitry coupled to the interconnect to detect the charge on the interconnect and to generate a signal indicating presence of the radiation in response to the charge. A method for triggering image acquisition in radiography includes coupling a switch between an interconnect and a detector, then charging an interconnect with that switch in response to radiation incident upon the switch while the switch is in an open-circuit state. Next, the charge on the interconnect is monitored and a signal is generated indicating the presence of the radiation in response to that charge.
