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 17):
A method of forming a representation of the particulate radiation impacting onto a semiconductor based pixelated detector having multiple detector pixels, each of the multiple detector pixels corresponding to multiple image pixels, the multiple 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 magnitude corresponding to the number of charges detected, (c) allocating the signal magnitude of each detector pixel to multiple image pixels within the detector; (d) estimating the position of the impact of the particle by determining a centroid of the image pixels within the multiple adjacent detector pixels, the allocation of the signal magnitude to multiple image pixels reducing the position dependent bias of the estimated position of the impact of the particle compared to the position dependent bias created by allocating the signal to a single image pixel, (e) repeating steps (a)-(d) to acquire estimated impact positions of multiple particles and forming a representation of the radiation using the multiple estimated impact positions. (f) forming a representation of the particulate radiation using the estimated positions of a multitude of impact positions.
