This paper presents preliminary experimental results obtained with a prototype SPECT system for small animal studies. This system is based on novel energy-resolved photon counting (ERPC) detectors we have recently developed for gamma ray imaging applications. The ERPC detector has basic modular configuration that offers an overall detection area of 4.5 cm × 4.5 cm, comprising of eight CdTe/CMOS detector...
In this paper, we present the design and preliminary performance of a novel energy-resolved photon-counting (ERPC) detector for gamma ray imaging applications. The prototype ERPC detector has an active area of 4.4 cm × 4.4 cm, pixelated into 128 × 128 square pixels of 350 μm × 350 μm in size. The current detector consists of eight hybrids. Each hybrid has a CdTe crystal of 1.1 cm ×2.2 cm × 1 mm, bump-bonded...
Virtually all bodily functions are controlled by electrical signals in nerves and muscles. Electrical stimulation can restore missing signals but this has been difficult to achieve practically because of limitations in the bioelectric interfaces. Wireless, injectable microdevices are versatile, robust and relatively inexpensive to implant in a variety of sites and applications. Several variants are...
