Description
New semiconductor detectors have recently gained a lot of attention for medical
applications in general. Advances in semiconductor detector arrays made of CdZnTe
or CdTe may improve both energy resolution and spatial resolution of clinical x-ray
systems. Alternative system designs based on TFA technology combining photodetector
arrays with CMOS electronics open a possibility for compact imaging cameras. This
scenario allows for the use of alternative materials such as a-Si:H and HgI2 that
can be applied alone or integrated with scintillators.
We present an overview of the potential photodetector and photoconductor candidates
for both computed tomography (CT) and positron emission tomography (PET)
applications. Preliminary experimental results obtained with the materials
mentioned above will be shown.
