Development of high-resolution detector module with depth of interaction identification for positron emission tomography
We have developed a Time-of-flight high resolution and commercially viable detector module for the application in small PET scanners. A new approach to depth of interaction (DOI) encoding with low complexity for a pixelated crystal array using a single side readout and 4-to-1 coupling between scintillators and photodetectors was investigated. In this method the DOI information is estimated usin...
متن کاملPerformance measurements of a depth-encoding PET detector module based on position-sensitive avalanche photodiode read-out.
We are developing a high-resolution, high-efficiency positron emission tomography (PET) detector module with depth of interaction (DOI) capability based on a lutetium oxyorthosilicate (LSO) scintillator array coupled at both ends to position-sensitive avalanche photodiodes (PSAPDs). In this paper we present the DOI resolution, energy resolution and timing resolution results for complete detecto...
متن کاملHigh luminance hybrid light guide plate for backlight module application.
We introduce a hybrid backlight module, which consists of a hybrid light guide plate (HLGP) and a brightness enhancement film (BEF). The HLGP comprises functions of a conventional light guide plate, a reflector, and a BEF. The HLGP allows one-dimensional rays to be collimated. We add a BEF above the HLGP, and let the crossed-dimension rays to be collimated. Comparing with the conventional edge-...
متن کاملOnline detector response calculations for high-resolution PET image reconstruction.
Positron emission tomography systems are best described by a linear shift-varying model. However, image reconstruction often assumes simplified shift-invariant models to the detriment of image quality and quantitative accuracy. We investigated a shift-varying model of the geometrical system response based on an analytical formulation. The model was incorporated within a list-mode, fully 3D iter...
متن کاملDesign of a High-Resolution and High-Sensitivity Scintillation Crystal Array for PET With Nearly Complete Light Collection
Spatial resolution improvements in positron emission tomography (PET) can be achieved by developing detector arrays with finer resolution elements. To maintain high sensitivity and image quality, the challenge is to develop a finely pixellated scintillation crystal array with both high detection efficiency and high light collection. High detection efficiency means the crystals must be relativel...
