Abstract:
When detecting particulate radiation, such as electrons, with a pixelated detector, a cloud of electron/hole pairs is formed in the detector. Using the signal caused by this cloud of electron/hole pairs, a position of the impact is estimated. When the size of the cloud is comparable to the pixel size, or much smaller, the estimated position shows a strong bias to the center of the pixel and the corners, as well to the middle of the borders. This hinders forming an image with super-resolution. By shifting the position or by attributing the electron to several sub-pixels this bias can be countered, resulting in a more truthful representation.

Claim (Index 8):
A method of detecting particulate radiation using a semiconductor based pixelated detector having detector pixels, the detector pixels having a detector pixel size, each particle of the particulate radiation causing formation of an electron/hole pair cloud in the semiconductor material of the detector, the cloud having a centroid and an extent, the extent of cloud being larger than the detector pixel size, the method comprising:\n (a) intercepting a particle of the particulate radiation, (b) detecting charges from the electron/hole cloud at multiple adjacent detector pixels to generate a signal from each of the multiple adjacent detector pixels, the signal having a magnitude corresponding to the number of charges detected, (c) estimating the position of a centroid of the electron/hole cloud using the magnitudes of the signals generated from the multiple adjacent detector pixels, the estimated position having a position dependent bias depending upon the position of the particle impact within the multiple adjacent detector pixels, and (d) estimating the impact position of the particle using the estimated position of the centroid, including compensation for the position dependent bias.
