Calorimeter-assisted track finding algorithm takes advantage of the finely segmented electromagnetic calorimeter proposed for the SiD detector concept by looking for ”MIP stubs” produced by charged particles in the calorimeter, and using them as seeds for pattern recognition in the tracker. The algorithm allows for efficient reconstruction of tracks that cannot be found using seeds provided by ...

I nformation of the segmented left ventricular (LV) area supplied by every coronary artery is potentially useful for strategy and practice of percutaneous coronary intervention, coronary artery bypass surgery, or percutaneous transluminal septal myocardial ablation (PTSMA). 2 Myocardial contrast echocardiography (MCE) with intracoronary contrast injection has been used to evaluate the segmented...

One of the most popular approaches to continuous-flow analysis in recent years has been the technique of flow-injection analysis (FIA) 1-3]. In essence, FIA relies on the mixing of a sample with specific reagents in a continuously flowing stream of carrier liquid while travelling to a detector. The detector monitors some property of the liquid which undergoes a change according to the extent of...

Aberration-corrected scanning transmission electron microscopy (STEM) has become an indispensable tool for characterizing atomic-scale structure in materials and devices. In STEM, a finely focused electron probe is scanned across the specimen and transmitted and/or scattered electrons from a localized material volume are detected by the post specimen detector(s) as a function of raster position...

Multi-element (4x4) imaging arrays with high resolution collimators, size matched to discrete CsI(T1) scintillator arrays and mercuric iodide photodetector arrays (HgI, PDA) are under development as prototypes for larger 16x16 element arrays. The compact nature of the arrays allows detector positioning in proximity to the breast to eliminate activity not in the lineof-sight 0; the collimator, t...

The Micro-Vertex Detector (MVD) of the CBM experiment requires very light detector stations equipped with highly granular and thin pixel sensors adapted to hostile running conditions. CMOS pixel sensors of the MIMOSA series are being developed for several years in ordre to match the challenging specifications of the MVD. Breakthroughs were achieved in 2009, which concern the fast sensor read-ou...

BACKGROUND Monolithic scintillators read out by arrays of photodetectors represent a promising solution to obtain high spatial resolution and the depth of interaction (DOI) of the annihilation photon. We have recently investigated a detector geometry composed of a monolithic scintillator readout on two sides by silicon photomultiplier (SiPM) arrays, and we have proposed two parameters for the D...

An individual readout of silicon photomultipliers (SiPMs) would enhance the performance modern positron emission tomography (PET) systems. However, as it difficult to achieve in practice, a multiplexing SiPM arrays could be performed instead. In this study, we characterized three PET detector modules utilizing different models with active areas 3 × 3, 4 4, and 6 mm2. Each array was coupled LYSO...
