June 16, 2008 – Siemens introduced IQ•SPECT, a works-in-progress that is the newest Symbia feature that enables a comprehensive cardiac evaluation including perfusion, attenuation correction and calcium scoring, in five minutes.
IQ•SPECT technology is achieved with SMARTZOOM, a specially designed “smart” collimator that magnifies the heart while imaging the rest of the torso under traditional conditions. Typically, cardiac SPECT data is obtained through keeping the detectors positioned at 90 degrees and as close to the body as possible, utilizing mechanically centered detector rotation, where organ specific magnification cannot be achieved.
The flexible mechanics of the Symbia S and T gantries allow an organ centric detector rotation that can zero-in on the organ of interest; in this case, the heart. Combining this organ centric orbit acquisition technique, fast, 3D iterative reconstruction that is optimized for more confident diagnoses, and improved patient comfort from a quicker scan, IQ•SPECT will set the standard for image quality, speed, productivity and throughput.
IQ•SPECT will be available for all new Symbia S and T systems, and is field upgradeable for any existing Symbia S or T systems that are already widely available in leading hospitals and imaging centers across the globe. The new SMARTZOOM feature is integrated into the current Symbia workflows and automation features, giving users access to the most flexible and versatile system available today.
From a user perspective, IQ•SPECT is fully automated and can therefore accommodate more patients per day and meet a variety of patient needs. For example, pediatric patients can benefit from a lower injected dose in regular acquisition time, or from less motion and more comfort with a regular dose and quicker acquisition time. A quicker scan allows for less patient movement and lowers the probability of retakes.
