combined pet/ct scanners now play a major role in medicine for in vivo imaging in oncology, cardiology, neurology, and psychiatry. as the performance of a scanner depends not only on the scintillating material but also on the scanner design, with regards to the advent of newer scanners, there is a need to optimize acquisition protocols as well as to compare scanner performances on an objective ...

Introduction:MAMMI is a dedicated PET based on high resolution detectors placed close to the breast. In this study, we presented a GATE model for the simulation of MAMMI scanner and model its performance of the MAMMI based on an adaptation of the NU 4-2008 NEMA standard. Methods:A detailed of geometry MAMMI system that uses scintillation crystals coupled...
Working in the low cost 3D scanner design domain, it would be very interesting to employ inertial technologies because they could provide objects surface spatial data, recording they movement moving, and asking a very low cost in term of sensor investment. Unfortunately these technologies are characterised by distortion problems that normally do not allow to obtain satisfying measures for being...
INTRODUCTION Large volume laser scanners are used for a variety of purposes, including dimensional metrology of large artifacts, digitization and reverse engineering, as well as historical preservation and archiving. These devices exploit the propagative properties of structured light (in this case, lased light) to collect spatial information of objects in the field of view. Laser scanners empl...
