PET-TOF study of Silicon Photomultipliers with DRS4 Readout
Our goal is to develop a system with 100 picosecond time resolution for time of flight positron emission tomography [PET-TOF] using silicon photomultipliers (SiPMs). We have obtained a coincidence time resolution of 188 ps FWHM with two LYSO crystals (3x3x15 mm) coupled to SiPMs and irradiated with Na source. The best time resolution was obtained with the signal trimmed by a clipping capacitanc...
متن کاملFirst results with SiPM tiles for TOF PET based on FBK RGB-HD technology
Fondazione Bruno Kessler, Trento, Italy We present the first results of timing and energy resolution of two newly developed tiles based on FBK RGB-HD SiPMs. The first tile has dimensions of 32×32 mm and is composed of 8×8 SiPMs, with a regular pitch of 4 mm and a cell size of 25×25 μm. Although manufactured with a standard bond wire technology, the tile achieves a fill factor at the tile level ...
متن کاملTime-Optimized High-Resolution Readout-Segmented Diffusion Tensor Imaging
Readout-segmented echo planar imaging with 2D navigator-based reacquisition is an uprising technique enabling the sampling of high-resolution diffusion images with reduced susceptibility artifacts. However, low signal from the small voxels and long scan times hamper the clinical applicability. Therefore, we introduce a regularization algorithm based on total variation that is applied directly o...
متن کاملCS-ToF: High-resolution compressive time-of-flight imaging.
Three-dimensional imaging using Time-of-flight (ToF) sensors is rapidly gaining widespread adoption in many applications due to their cost effectiveness, simplicity, and compact size. However, the current generation of ToF cameras suffers from low spatial resolution due to physical fabrication limitations. In this paper, we propose CS-ToF, an imaging architecture to achieve high spatial resolut...
متن کاملHigh-resolution TOF with RPCs
In this work, we describe some recent results concerning the application of Resistive Plate Chambers operated in avalanche mode at atmospheric pressure for high-resolution time-of-flight measurements. A combination of multiple, mechanically accurate, thin gas gaps and state-of-the-art electronics yielded an overall (detector plus electronics) timing accuracy better than 50 ps s with a detection...
