Publication number: 20130044248Abstract: New sensors and different embodiments of multi-channel integrated circuit are provided. The new high energy and spatial resolution sensors use both solid state and scintillator detectors. Each channel of the readout chip employs low noise charge sensitive preamplifier(s) at its input followed by other circuitry. The different embodiments of the sensors and the integrated circuit are designed to produce high energy and/or spatial resolution two-dimensional and three-dimensional imaging for widely different applications. Some of these applications may require fast data acquisition, some others may need ultra high energy resolution, and a separate portion may require very high contrast. The embodiments described herein addresses all these issues and also other issues that may be useful in two and three dimensional medical and industrial imaging.Type: ApplicationFiled: January 7, 2011Publication date: February 21, 2013Applicant: NOVA R & D, INC.Inventors: Tumay O.

Publication number: 20110248765Abstract: A readout electronics scheme is under development for high resolution, compact PET (positron emission tomography) imagers based on LSO (lutetium ortho-oxysilicate, Lu2SiO5) scintillator and avalanche photodiode (APD) arrays. The key is to obtain sufficient timing and energy resolution at a low power level, less than about 30 mW per channel, including all required functions. To this end, a simple leading edge level crossing discriminator is used, in combination with a transimpedance preamplifier. The APD used has a gain of order 1,000, and an output noise current of several pA/?Hz, allowing bipolar technology to be used instead of CMOS, for increased speed and power efficiency. A prototype of the preamplifier and discriminator has been constructed, achieving timing resolution of 1.5 ns FWHM, 2.7 ns full width at one tenth maximum, relative to an LSO/PMT detector, and an energy resolution of 13.6% FWHM at 511 keV, while operating at a power level of 22 mW per channel.Type: ApplicationFiled: October 8, 2010Publication date: October 13, 2011Applicant: NOVA R&D, INC.Inventors: Tumay O.
