Hybridyne Medical Imaging System OK’d by FDA

Facebook Twitter LinkedIn Email Comments
TORONTO, April 29, 2010 — Hybridyne Imaging Technologies Inc. announced it has received FDA clearance for its ProxiScan system.

Using planar imaging techniques, the system can be used in imaging the distribution of radionuclides in the human body. It may also be used intra-operatively, on pathological specimens and for endocavity applications if a protective sheath is used.

It uses a small cadmium zinc telluride (CZT)-based compact gamma camera developed by the company in collaboration with scientists at Brookhaven National Laboratory. The size enables it to be placed close to the object of interest, reducing the possible radiation does to patients.

Additionally, it can deliver high-performance imaging of radiopharmaceuticals distributed within anatomical regions of interest located close to the camera head. This could impact medical applications, especially for the widespread need for better nuclear-medical imaging in cancer diagnostics.

When coupled with a suitable radioactive tracer, it has the potential to detect smaller lesions than conventional Anger cameras, said Dr. Youngho Seo, a faculty member at the Department of Radiology and Biomedical Imaging at the University of California, San Francisco.

Hybridyne develops compact gamma cameras fro imaging radiopharmaceuticals distributed in the body, using solid-state detectors and miniaturized digital circuits for creating new diagnostic tools and treatment capabilities.

1. A device designed to convert the energy of incident radiation into another form for the determination of the presence of the radiation. The device may function by electrical, photographic or visual means. 2. A device that provides an electric output that is a useful measure of the radiation that is incident on the device.
gamma camera
A camera used in scintillation recording to make a visible record of the distribution and relative concentration of radioactive tracer elements in a sample that is undergoing scanning.
The emission and/or propagation of energy through space or through a medium in the form of either waves or corpuscular emission.
radioactive tracer
A radioactive element that is placed or injected into a system to obtain an autoradiogram of the system. It is used in a number of fields where standard methods of internal imaging, for example, radiography, fail to produce a clear image.
