DoseCapture is a radiation detection system designed for real-time spectroscopic measurement of gamma rays: in particular, it has been designed for an optimal detection of photons with energy around 500 keV. Being equipped with four independent Virtual Frisch-grid CZT detectors arranged in a row (to form an array of 4 pixels) and with a parallel-holes 20 mm thick lead collimator, each DoseCapture module offers a coarse spatial resolution (roughly 5mm pitch). For each CZT sensor, anode and cathode signals are acquired synchronously and processed by the digital signal processing algorithm embedded in the digital signal processor (FPGA), to further improve the spectral resolution and signal-to-noise ratio.
Thanks to the combination of CZT semiconductor sensors, advanced digital readout and pulse processing, each DoseCapture module guarantees excellent spectroscopy even in the presence of intense background radiation.
DoseCapture is a modular component and can be assembled in linear arrays to form a multihead imaging system for applications such as BNCT-SPECT or SPECT.
