Abstract
A method of high-energy particle imaging by individual particle counting with an active pixel direct bombardment detector. The method includes the step of providing an active pixel direct bombardment detector including an array of pixels. Each pixel is characterized by a reset time constant. The method further includes sampling the pixel voltage of each pixel at a first time. The method further includes applying a pixel reset voltage to each pixel for a reset time interval less than the reset time constant. The method further includes sampling the pixel voltage of each pixel at a second time. The method further includes computing a difference between the sampled pixel voltages at the first and second times. The sampling and the applying of the reset voltage may be periodic. A direct bombardment detector is also provided.
