Novel Cardiac SPECT Technology with Semiconductor Detectors

Semiconductor Detectors - an Introduction

Microstructured semiconductor neutron detectors

Perforated semiconductor neutron detectors are compact diode detectors that operate at low power and can be fashioned to have high thermal neutron detection efficiency. Fabricated from high-purity Si wafers, the perforations are etched into the diode surface with ICP-RIE and backfilled with LiF neutron reactive material. The intrinsic thermal neutron detection efficiency depends upon many facto...

Semiconductor Photon Detectors

Semiconductor detectors allow low-dose-low-dose 1-day SPECT myocardial perfusion imaging.

UNLABELLED Cadmium zinc telluride (CZT) detectors with linear counting rate response enable count subtraction in sequential scanning. We evaluated whether count subtraction eliminated the need for higher activity doses in the second part of the 1-d stress-rest myocardial perfusion imaging (MPI) protocol. METHODS For 50 patients (mean age ± SD, 66 ± 12 y) with visually abnormal (n = 42) or equ...

Future Semiconductor Detectors Using Advanced Microelectronics with Post-processing, Hybridization and Packaging Technology

Several challenges for tracking with semiconductor detectors in the high rate environment of future elementary particle physics experiments are discussed, such as reduction of spurious hits and ambiguities and identification of short-lived 'messenger' particles inside jets. To meet these requirements the instrumentation increasingly calls on progress in microelectronics. Advanced silicon integr...
