Recent progress in the development of micro-cables for very densely packed silicon pad detector modules to be used in a Compton Prostate Probe is reported. The purpose of this development is to optimize the packaging and interconnection of 1mm thick silicon sensors with their readout electronics in such a way that the assembly thickness is dominated by the sensor thickness. Development of micro-cables demonstrate that TAB technology can replace wire bonding technology, which does not allow optimally dense packaging, with TAB bonded modules which have electronically equally good performance.

A first prostate probe prototype based on the Compton imaging technique has been developed, with a scatter detector composed of a stack of five thick silicon pad detectors, and absorption detector consisting of three Nal(Tl) scintillators placed around the scatter detector. A spatial resolution of 5 mm FWHM has been measured reconstructing an image of a point-like 133 Ba source placed at 11 cm distance from the scatter detector. Additional studies show the improvement of the detector resolution with increasing incident photon energy and distance from the scatter to the absorption detector.
