Study on Position-Sensitive Anode in Photon Counting Imaging Detector
Wedge and strip anode(WSA) is one of charge division anodes. In the photon counting imaging detector, the role of the WSA is to decode the incident position of photon events. The anode performance parameters have an important influence on the imaging performance of the detector. The inter-electrode capacitance of WSA is studied, and its calculation formula is obtained by the theoretical model. The WSA panel with different parameters is designed and prepared. The relationship between cycle length, insulation gap width, anode collecting area, substrate material and the anode inter-electrode capacitance is analyzed. Test results show that the inter-electrode capacitance is in accordance with the theoretical calculation result and the deviation between calculated value and test value is within 10%.
