SNM: Siemens debuts dose-reduction PET/CT software
Siemens Healthcare introduced Iterative Reconstruction in Image Space (IRIS) CT technology for molecular imaging at the SNM annual meeting in Salt Lake City last week. By adding IRIS CT to the TrueV and HD technologies already available with Siemens Biograph family of PET/CT scanners, the company said users can achieve about 60 percent dose reduction.
IRIS applies the raw data reconstruction only once, Siemens said. During this newly developed initial raw data reconstruction, a master image is generated that contains the full amount of raw data information. The following iterative corrections known from true iterative reconstruction are consecutively performed in the image space. The technology helps overcome processing of theoretical iterative reconstruction, according to the company.
Siemens also featured the first clinical results from the Symbia IQ•SPECT SPECT/CT scanner—which debuted two years ago at SNM—that acquires images at double the scan speed of conventional SPECT imaging and with half the injected dose, according to the company. Systems will begin shipping August 30th. To date, seven units have been placed in the U.S., France, Japan and the Netherlands.
