Excerpt

The main part of the IQ•SPECT tomographic system developed by Siemens dedicated to cardiac imaging is a multifocal collimator called SMARTZOOM. The system can be installed on Symbia cameras from the same manufacturer. Besides a pair of SMARTZOOM collimators, it includes cardiocentric acquisition software and reconstruction software that takes into account this particular geometry of detection in an OSEM algorithm and can correct for scatter diffusion. Although presented as optional by the manufacturer, attenuation correction (AC) using a CT scan (with 2 to 16 detectors, depending on the exact model of Symbia camera) is an additional and essential feature. The multifocal geometry of SMARTZOOM enables magnification of the centre of the field of view where the heart lies by a factor of up to four while avoiding truncation of lateral parts of the patient’s torso. …
