1. An intraoral x-ray sensor system comprising:
a pixel circuit associated with each of one or more pixels of an array of pixels and configured to integrate x-ray pulse energy received at the associated pixel, in response to a trigger;
a multiplexer configured to readout analog signals from the array of pixels into two or more parallel channels;
two or more analog to digital converter (ADC) circuits configured to perform parallel conversion of the analog signals of the channels into digital signals, such that each ADC receives the analog signal of a corresponding one of the parallel channels;
a memory; and
a controller circuit configured to store the digital signals in the memory as a frame of data.
