Gamma Camera Breast Imaging Lexicon
American Journal of Roentgenology, 2012The standardized terminology and reporting structure of the BI-RADS for mammography, ultrasound, and MRI findings facilitates patient management. To date, no such terminology has been available for gamma camera breast imaging. We present an illustrated lexicon including description of background uptake, mass and nonmass uptake, lesion intensity ...

CZT gamma camera for scintimammography
Physica Medica, 2006A high performance prototype gamma camera based on the semiconductor radiation detector Cd(Zn)Te is described. The camera features high spatial resolution, high-energy resolution, a reduced dead space on the edge of the field of view, and a compact format.

Reproducibility of gamma camera data
Physics in Medicine & Biology, 1981The increasing use of quantification in the interpretation of nuclear medicine images requires a knowledge of the errors associated with the estimation of the activity in a volume of interest from the recorded count rate data. Using sources of known cross-sectional area from 1 to 25 cm2, errors caused by variations in the count rate, day of measurement,

Nuclear cardiology imaging is traditionally performed on an Anger gamma camera. Its key component is a large, flat, circular or rectangular sodium iodide crystal, activated by non-radioactive thallium (NaI(Tl)). The side of the crystal facing the patient is covered with a lead collimator, while the side away from the patient is viewed by an array of ...

This chapter describes the principles of operation of a gamma camera and explains how it can be used to acquire SPECT studies. Hybrid SPECT/CT systems are introduced. Methods of reconstructing SPECT images using filtered back projection or iterative reconstruction, including attenuation correction, scatter correction, and resolution recovery, are ...
