Gamma will feature its dual-modality in-vivo preclinical animal imaging system.
X-SPECT combines SPECT with CT, and is similar to clinical systems, but on a smaller scale and with dedicated features suited to the in-vivo imaging of animals in a laboratory setting. The system acquires, processes, and displays fused SPECT/CT with a choice of single-head or dual-head gamma detectors with pinhole, parallel hole, multiple pinhole, and diverging parallel hole image acquisition options.
The product includes choices of two sizes of CT detectors, a 2-inch detector with 1024 X 1024 pixels and 48 mm pitch for mice only, and a 4.72-inch detector with 2048 X 2048 pixels and 50 mm pitch, for mice, rats, rabbits, rhesus monkeys, said Gamma Medica. In addition, the X-SPECT permits the imaging of standard SPECT isotopes such as technetium-99m and iodine-123 as well as medium-to-high energy isotopes such as lutetium-177 and indium-111 and low energy isotopes such as iodine-125.
The system also permits real-time CT reconstruction of images as acquired up to a 5123 matrix. 10243 matrix (30 minutes) and 20483 matrix (<4 hours) images are processed off-line, according to the firm. The system, available now worldwide, is used primarily in the study of disease processes and for drug development, Gamma Medica said.
The developer will also be showing its XO micro CT system for in-vivo preclinical imaging. XO, the CT modality of the firm’s X-SPECT system, is plumbed for isofluorane anesthesia and the running of probes and catheters. The product features the company’s LoTox technology, which shields an animal from x-rays during detector movement to lower overall subject dose, according to Gamma Medica.
The XO micro CT system will be available this quarter, the company said.
