Next generation of the Albira small animal PET based on high density SiPM arrays

2015

A new design of the small animal PET Albira system which detectors are based on arrays of SiPMs and monolithic LYSO scintillator is presented here. The system is made out of 3 rings of 8 detectors each, resulting on an axial and transaxial FOVs of 148 and 80 mm, respectively. The scanner is thermally stabilized using air-cooling. Working temperatures around 22–25°C are reached with individual detector variations around 0.2°C minimizing dark count rates and gain drifts. One of the most significant improvements of the current system is the accurate photon impact determination within the crystal volume, specially its depth of interaction. This allows the calculation of the true line of respons…

DOI measurement with monolithic scintillation crystals: A primary performance evaluation

2007

We report a first assessment of image quality enhancement achieved by the implementation of depth of interaction detection with monolithic crystals. The method of interaction depth measurement is based on analogue computation of the standard deviation with an enhanced charge divider readout. This technique of depth of interaction detection was developed in order to provide fast and determination of this parameter at a reasonable increase of detector cost. The detector consists of an large-sized monolithic scintillator coupled to a position sensitive photomultiplier tube. A special design feature is the flat-topped pyramidal shape of the crystal. This reduces image compression near the edges…

Intelligent robotic cell for Trencad/spl inodot//spl acute/s mosaics manufacturing

2005

The purpose of this paper is the description of an application for the complete automation of a mosaics manufacturing process with irregular random pieces, so called trencad/spl inodot//spl acute/s. An intelligent robotic cell has been implemented by using intelligent methods and pattern recognition techniques to assemble unpredictable objects in an autonomous manner.
