EndoTOFPET-US DAQ, designing the Data Acquisition System of a high resolution endoscopic PET-US detector
Carlos Zorraquino,Ricardo Bugalho,M. Rolo,José C. Da Silva,Viesturs Veckalns,Rui F. Silva,Catarina Ortigao,Jorge A. Neves,Stefaan Tavernier,Joao Varela +9 more
TL;DR: This contribution summarizes main aspects of the EndoTOFPET-US detector focusing on the parts directly related with its DAQ system and makes a detailed study concerning the Data Acquisition System itself.
Journal ArticleDOI
Characterization of avalanche photodiode arrays for the ClearPEM and ClearPEM-Sonic scanners
R. Bugalho,B. Carrico,Cláudia Ferreira,M. Frade,Miguel A. Ferreira,R. Moura,Jorge A. Neves,Catarina Ortigao,J. F. Pinheiro,Pedro Rodrigues,I. Rolo,João Carlos Silva,Rui F. Silva,A. Trindade,Joao Varela,Joao Varela +15 more
TL;DR: ClearPEM as discussed by the authors is a high-resolution Positron Emission Mammography prototype, developed by the Portuguese PET Consortium in the framework of the Crystal Clear Collaboration at the European Organization for Nuclear Research (CERN).
Journal ArticleDOI
Radioactive 222Rn daughter nuclides on a paper strip
TL;DR: In this paper, a simple iterative method is used as an alternative to the exact analytical solution to solve the radioactive decay chain equations, which can be used as a simple alternative to exact analytical solutions.
Journal ArticleDOI
Feasibility and electromagnetic compatibility study of the ClearPEM front-end electronics for simultaneous PET-MR imaging
J.A. Neves,J.A. Neves,J.A. Neves,R. Bugalho,R. Bugalho,Rolf Gruetter,Rolf Gruetter,Rolf Gruetter,Arthur W. Magill,Arthur W. Magill,Catarina Ortigao,José C. Da Silva,Rui Silva,Joao Varela,Joao Varela,Joao Varela +15 more
TL;DR: In this article, the authors presented a feasibility study of the ClearPEM technology for simultaneous PET-MR imaging on a 7 T magnet by characterizing the response behavior of the PET detectors and front-end electronics to pulsed RF power and switched magnetic field gradients.
