摘要:
A method of radioimaging a myocardial perfusion, the method including in sequence: administering to a subject a low dose of a first radiopharmaceutical; subjecting the subject to a physical stress; administering to the subject at a peak of said physical stress a medium or high dose of a second radiopharmaceutical; and immediately radioimaging using a 3D non-coincidence imaging method a heart of the subject, thereby radioimaging a myocardial perfusion.
摘要:
A method for predefining a set of radioactive-emission measurement views, for radioactive-emission imaging after an administration of a radiopharmaceutical, the method being tailored to a specific body structure and optimized with respect to the information gained about the body structure and based on modeling body-structure, based on its geometry and anatomical constraints, which limit accessibility to the body structure.
摘要:
Apparatus is provided for use with at least one labeled radiopharmaceutical agent, the apparatus including a container (22) containing the at least one labeled radiopharmaceutical agent, and a portable computer-communicatable data carrier (120, 24) associated with the container (22), the data carrier (120, 24) containing imaging protocol information for use with the at least one labeled radiopharmaceutical agent. Other embodiments are also described.
摘要:
A method of radioactive-emission-measurement. The method comprises providing a camera for the detection of single emissions, which defines proximal and distal ends. The camera is configured for enabling a reconstruction of a volumetric image having a line spread function of less than 7 mm Full Width Half Maximum (FWHM) when given a substantially line source of radioactive emission, with an activity of 5 mCi, within a region-of-interest volume, at a distance of at least 100 mm from said distal end, with air being substantially the only operating medium. The method further comprises detecting at least 1 of every 5000 photons, emitted from at least one radioactive-emission source, located within a certain region-of-interest volume, using the camera, and reconstructing a volumetric radioactive-emission image from the detected photons.

摘要:
A method for stabilizing the reconstruction of an imaged volume is presented. The method includes the steps of performing an analysis of the reliability of reconstruction of a radioactive-emission density distribution of the volume from radiation detected over a specified set of views, and defining modifications to the reconstruction process and/or data collection process to improve the reliability of reconstruction, in accordance with the analysis.
摘要:
An implantable lead connector configured for long term implantation and to electrically interconnect multiple medical devices and to channel electrical signals between said interconnected devices and a target organ, comprising: a first port adapted to receive a first signal suitable to stimulate a target tissue, a second port adapted to receive a second signal suitable to stimulate a target tissue, and a third port configured to connect to a target organ, wherein at least one of said first and second ports is configured to connect to a signal generator not integrated with said connector.
摘要:
Systems, methods, and probes are provided for functional imaging by radioactive-emission-measurements, specific to body structures, such as the prostate, the esophagus, the cervix, the uterus, the ovaries, the heart, the breast, the brain, and the whole body, and other body structures. The nuclear imaging may be performed alone, or together with structural imaging, for example, by x-rays, ultrasound, or MRI. Preferably, the radioactive-emission-measuring probes include detectors, which are adapted for individual motions with respect to the probe housings, to generate views from different orientations and to change their view orientations. These motions are optimized with respect to functional information gained about the body structure, by identifying preferred sets of views for measurements, based on models of the body structures and information theoretic measures. A second iteration, for identifying preferred sets of views for measurements of a portion of a body structure, based on models of a location of a pathology that has been identified, makes it possible, in effect, to zoom in on a suspected pathology. The systems are preprogrammed to provide these motions automatically.
