The aim of the present invention is to develop a modular scintigraphic device, with high spatial resolution, capable of creating investigation areas of various shapes and sizes, of compact form and of being used in different types of applications. In particular, all the variants proposed solve a series of problems linked to the use of the new MPPC (Multi Pixels Photon Counters) instead of the traditional phototubes and PSMPT (Position Sensitive Photo Multiplier Tube), thus making it possible to create extremely compact devices that are easier to use, especially in environments such as operating theatres and in robotic surgery. These modular structures can therefore be produced in such a way as to lower the overall costs of the devices and be suitable for introduction into important hospital environments such as operating theatres, to facilitate localisation techniques during surgery.
The method makes it possible to use individual MPPC modules or individual SiPMs as collection anodes on which the scintillation elements can be arranged. Various versions of structures and ways of electronically connecting the modules are proposed, so that independent detection structures or a single detection structure can be realised. The detection areas can be constructed in any size and without limitation to the number of MPPC modules.
