The electronics system for the LBNL Positron Emission Mammography (PEM) camera

W. W. Moses; J. W. Young; K. Baker; W. Jones; M. Lenox; M. H. Ho; M. Weng 2000 IEEE Nuclear Science Symposium. Conference Record (Cat. No.00CH37149), 2000

Summary form only received as follows: Describes the electronics for a high performance Positron Emission Mammography (PEM) camera. It is based on the electronics for a human brain PET camera (the Siemens/CTI HRRT), modified to use a detector module that incorporates a photodiode (PD) array. An ASIC services the PD array, amplifying its signal and identifying the crystal of interaction. ...


The Road to the Common PET/CT Detector

A. Nassalski; M. Moszynski; T. Szczesniak; D. Wolski; T. Batsch 2006 IEEE Nuclear Science Symposium Conference Record, 2006

Growing interest in the development of dual modality positron emission/X-rays tomography (PET/CT) systems prompts researchers to face a new challenge: to acquire both the anatomical and functional information in the same measurement, simultaneously using the same detection system and electronics. The aim of this work was to study a detector consisting of LaBr3, LSO or LYSO pixel crystals coupled to ...


Fermi's golden rule, nonequilibrium electron capture from the wetting layer, and the modulation response in P-doped quantum-dot lasers

D. G. Deppe; H. Huang IEEE Journal of Quantum Electronics, 2006

Electron capture from a quantum dot's (QDs) wetting layer is described by Fermi's golden rule that relates the transition rate to the density of final states. The wetting layer capture causes a brief nonequilibrium electron distribution between the QD ground state and its wetting layer states and can slow a QD laser's modulation response. This effect is studied for time ...


Real-Time Viewer for Positron Emission Mammography Guided Biopsy

Xiaohong Lu; Edward Anashkin; Christopher G. Matthews; Weidong Luo IEEE Transactions on Nuclear Science, 2010

PEM-guided biopsy is successful in localizing sub-centimeter lesions that cannot be seen by other modalities. To help the physician quickly visualize the position of an interventional device in relation to a lesion, we have developed a method to view PEM images in near real time, allowing visualization of lesion displacement within 30 seconds. Phantom and patient data were collected on ...


A high-performance VME-based acquisition system for positron emission mammography

D. J. Abbott; A. Weisenberger; S. Majewski; D. Kieper; B. Kross; V. Popov; R. Wojick 2001 IEEE Nuclear Science Symposium Conference Record (Cat. No.01CH37310), 2001

A prototype for a practical and economical breast imaging system for cancer detection is currently under development at Jefferson Lab. The latest advances in bright, fast, crystal scintillators, compact position-sensitive photomultipliers (PSPMT), and high-performance digitizing and readout electronics are being used to develop a compact imager based on Positron Emission Tomography (PET). To facilitate the performance demands of the detector ...

  • Fundamentals of Electrical Discharges

    Natural phenomena, such as gamma rays produced by radioactive decay processes in the soil and cosmic radiation originating from solar flares and other galactic objects, can ionize the air molecules. This chapter first discusses ionization and deionization processes in gases. This is followed by a discussion on ionization and attachment coefficients. Two typical breakdown mechanisms occur in gases, each of them operating under specifically favorable conditions: Townsend's mechanism and the streamer mechanism. Corona discharges in air can burn on the overstressed zones of hot electrodes. This kind of discharge occupies a short layer, attached to the energized conductor. When a conductor is in corona, then the electric field on the surface is somehow influenced by the surrounding ion space charge. Kaptzov's hypothesis (KH) relates to the assumption that the space charge emitted into the interelectrode gap is in amounts that hold the surface field at the onset level.
