Radiopharmaceutical producer International Isotopes this month signed a technology development deal with a Texas university that the company hopes will lead to a nuclear medicine camera with up to four times the resolution of systems on the market. International Isotopes of Denton, TX, is combining its nuclear medicine patent portfolio with that of University of Texas Southwestern Medical Center in Dallas to develop the camera, according to Carl Seidel, president and CEO.

The system to be developed could be either a PET or SPECT camera, or a combination of the two technologies, Seidel said. International Isotopes believes that the camera is capable of spatial resolution in the 0.5-mm to 1.3-mm range, which would be a fourfold improvement on conventional gamma cameras.

The camera achieves such high specifications through noise reduction and better detectors, Seidel said. The system's detectors will be based on digital technology, although the company declined to specify whether it will be a solid-state unit. International Isotopes is in discussions with other vendors regarding a manufacturing agreement for the system.

In other International Isotopes news, the company last month raised $10 million through a private stock placement. The funds will be used to complete installation of the cyclotron and linear accelerator that International Isotopes will use to produce radioisotopes.
