LIQUID XENON MULTIWIRE PROPORTIONAL CHAMBERS FOR NUCLEAR MEDICINEAPPLICATIONS

Description: The need for improved spatial resolution in nuclear medicine has long been recognized. Notable attempts to achieve this goal are the gas-filled wire chambers and solid-state detectors. (1) However, at energies above 100 keV, gas-filled chambers suffer from poor detection efficiency and a long recoil electron range in the gas. While it is advantageous to pressurize these chambers to 10 or more atmospheres, structural design of the thin window presents a formidable task. High-resolution optimal c… more

Energy and environment annual report 1974. [Environmental Research programs]

Description: Research in the Division's environmental science program includes air pollution, water pollution, and the effects of pollutants on man and natural ecosystems. Work has focused on the chemistry and physics of particle surfaces. Using the technique of electron spectroscopy for chemical analysis (ESCA), surface reactions of sulfur and nitrogen compounds have been studied, and results include the identification of new chemical forms of nitrogen on particle surfaces and evidence for the importance o… more

Second Annual AEC Scientific Computer Information Exhange Meeting. Proceedings of the Technical Program Theme: Computer Graphics

Description: The topic of computer graphics serves well to illustrate that AEC affiliated scientific computing installations are well represented in the forefront of computing science activities. The participant response to the technical program was overwhelming--both in number of contributions and quality of the work described. Session I, entitled Advanced Systems, contains presentations describing systems that contain features not generally found in graphics facilities. These features can be roughly class… more

Labeling of blood cells with /sup 99m/Tc

Description: Erythrocytes, leukocytes, and tumor cells were labeled with /sup 99m/Tc to take advantage of the ideal physical properties of /sup 99m/Tc. Clinical studies indicate that labeled erythrocytes can be used to obtain improved vascular and splenic imaging as well as reliable red cell volumes. The erythrocytes have been labeled with and without the use of an added reducing agent. Two methods of adding the reducing agent stannous chloride have been proposed which differ in the order of addition of the… more

Three-dimensional reconstruction in nuclear medicine by iterative least- squares and fourier transform techniques

Description: Quantitative three-dimensional distribution of radioisotopes in patients is determined by digital reconstruction of data from many views taken by rotating the subject at 10 deg intervals before the gamma camera. The superiority of these techniques over conventional tomography is demonstrated by comparisons between reconstruction algorithms such as back-projection, simultaneous iterative reconstruction, iterative least-squares, and back-projection of filtered projection. The filtered back-projec… more

Acquisition, processing and display of gated cardiac scintigrams

Description: An improved method for non-traumatic and essentially noninvasive evaluation of left ventricular (LV) function with /sup 99m/Tc as the tracer was developed. This method combines previously used EKG gating techniques for cardiac blood pool visualization with new computerized acquisition, processing and display techniques. An Anger camera, a small computer, and a physiological synchronizer are used to acquire a sequence of eight scintigrams which span the entire cardiac cycle. Under our present pr… more
