A new method for optimizing the design of multi-aperture parallel-hole collimators for the gamma scintillation camera is presented. The method takes into account the frequency spectrum of a plane source object distribution as well as the energy of th

The detection of thermal asymmetry may lead to the diagnosis of significant disease states, especially those of a neoplastic or vascular nature. Estimates of acceptable thermal asymmetry have been made; thermal asymmetry has not previously been quant

Seventy four subjects treated for thyrotoxicosis with radioactive iodine (131I) were studied by means of an ethylenediamine tetra-acetate (EDTA) infusion such as was described by Kaiser & Pensold (1959). The response of these patients to a standard h

The surface topography of a patient can be determined by photogrammetry before beginning radiotherapy. The source light of the therapy unit or simulator is used to project a grid pattern onto the patient, and this is then photographed together with c

Thirty patients had bone scintigraphy with both Tc-99m pyrophosphate (Tc-PPi) and Tc-99m diphosphonate (Tc-HEDP). The images were given a composite rating for quality and the basis of three sets of criteria, and were also compared for the number of l
