SPECT Image-Enhancement System

The technology's ability to lessen scan times considerably reduces the potential of patient motion artifacts and increases throughput. With this system, developed by UltraSPECT (Brookfield, WI, USA), a gated stress image scan can be done in as little as five minutes with excellent image quality. The WBR application for stress and rest studies joins Xpress.bone and Xact.bone as the newest addition to the UltraSPECT line of products.

"Current nuclear medicine scan duration adversely affects image quality, capital equipment utilization, and patient throughput,” stated Salvador Borges-Neto, M.D., director of nuclear cardiology laboratories for Duke University Medical Center (Durham, NC, USA). "Nuclear cardiology, in particular, must become more efficient to compete with new cardiac imaging modalities and increasingly popular hybrid SPECT/CT cameras. The Xpress.cardiac protocol is very promising in solving these problems.”

The WBR allows for increased scan speed by providing a more accurate description of the physical model of the emission-detection process than other reconstruction techniques by removing the negative effect of the collimator line spread function (LSF) on the spatial resolution. The improved accuracy of the first phase of the process reduces the scan time required to produce a diagnostic quality image. The WBR technology provides the first real improvement in SPECT image resolution and scanning efficiency and can also compensate for the physical effects of attenuation and scatter.
