In this article we present the conception, technological fabrication and electrical characterization of 3D hybrid pixel detector modules based on read out chips (ROCs) with through silicon vias (TSVs) which are flip chip bonded onto silicon photon sensors for X-ray detection. The TSVs in the ROCs enable a vertical routing of their peripheral IOs to the back side where they are spread to a land grind...
A promising transducer architecture for largearea arrays employs 2-D capacitive micromachined ultrasound transducer (CMUT) devices with backside trench-frame pillar interconnects. Reconfigurable array (RA) application-specified integrated circuits (ASICs) can provide efficient interfacing between these high-element-count transducer arrays and standard ultrasound systems. Standard electronic assembly...
Gaseous detectors with a highly pixelized readout have demonstrated good capabilities of tracking high energetic particles. In particular, using post-processing methods to integrate the gas amplification stage on top of pixel readout chips has proven to detect single electrons with a very high efficiency and accuracy. So far, these detectors called InGrids or GEMGrids have been produced in a chip...
Background: Harmonic power Doppler imaging is a novel technique for the assessment of myocardial perfusion by contrast echocardiography. In this study, we examined whether myocardial contrast echocardiography using harmonic power Doppler and the new transvenous contrast agent SHU 563A can identify myocardial perfusion defects during coronary occlusion and reperfusion. Methods: To assess the potential...
