In this latter case, the unit 24 will be substituted by a unit that converts the nuclear image received by the detector 10 into a sequence of electric image signals. Such a unit may contain a conventional Anger camera. In FIG. 2 a portion of the signal processing circuitry 20 of FIG....
(including the study of normal anatomy and physiology). Medical imaging technology includes: radiography including x-rays, fluoroscopy, and x-ray computed axial tomography (CAT or CT); magnetic resonance imaging (MRI); and nuclear medical imaging such as scintigraphy using a gamma camera, single ...
4.The method according to claim 1, wherein said nuclear imaging modality is a dual-head gamma camera. 5.The method according to claim 4, wherein said heads are oriented at 90 degrees with respect to each other during said imaging of said point source. ...
A gamma camera within a signal generating system encompassing a stage converting an image which is to be photographed into an electron image, following which there is a locating or position-finding system from
by a tracer which is conventionally administered to a patient in nuclear medicine. The half-life of americium is several hundred years. This has the advantage that during patient examination and during the lifetime of a scintillation camera, a replacement of the radiation source 2 is not ...
The same problem arises in nuclear medicine, especially in the application of gamma cameras, such as Anger cameras, for example. With this imaging technique, in a similar way to x-ray diagnostics, as few scattered gamma quanta as possible should reach the detector. By contrast with x-ray dia...
25.A gamma camera according to claim 11, wherein photodetectors are coupled to both ends of each bar detector strip of said stack. Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention generally relates to nuclear medicine, and systems for obtaining nuclear med...
Code validationSIMIND Septal penetration fractionMonte CarloThe use of Monte Carlo (MC) simulations in nuclear medicine is on the rise due to its usefulness in modelling many physical phenomena which are difficult or impossible to measure. To use MC for gamma......
In a nuclear medicine camera, there are several ways to mount the drive system. One way of mounting the drive system to the gantry is to mount the drive system to the stand to achieve proper tooth alignment (pinion gear centerline is parallel to ring centerline). Here, the stand often has...
a planar gamma camera; an X-ray CT scanner; a planar X-ray device; an MRI device; and an optical imager, said second imaging device defining a patient gantry for receipt of said patient support and the patient therein; a substrate configured to be carried by the patient bed and within ...
