Dynamic spatial reconstructor
WebA new imaging device, the dynamic spatial reconstructor (DSR), is described. It differs from commercially available computed tomography scanners in several ways. It images a volume rather than a slice; it images the volume in stop-action to minimize blurring due to motion; and it repeats the scan 60 times per second so that the functional ... WebJan 12, 2013 · The idea of dynamically acquired CT data is not new. In fact, two unconventional CT designs, the Dynamic Spatial Reconstructor [] (DSR) and the Imatron electron beam scanner [6, 7] were both built in the 1980s primarily as dynamic scanners focused on cardiac imaging (Fig. 1).The DSR consisted of 28 x-ray tubes mounted in a …

WebIn the early 1980s, initial experience with the so-called dynamic spatial reconstructor (DSR) had demonstrated a potential diagnostic value of cardiac CT imaging (BEHRENBECK et al. 1982; ROBB et al. 1983). However, the DSR had limited spatial resolution and was a very complex system. It was never manufactured commercially.
WebThe Dynamic Spatial Reconstructor system has been developed to dynamically (up to 60/sec) image the entire 3-D volume (up to 240 adjacent 1-mm-thick transverse sections) encompassing moving organs of the body, particularly the heart and lungs, or the circulation in any organ. This capability permits accurate regional and global measurements to ...
