Die PET/CT system family Biograph by Siemens Medical Solutions welcomes a new member - the Biography 64. The innovative hybrid system combines Positron Emission Tomography (PET) with the fastest Computed Tomograph by Siemens, the 64 slice CT system Somatom 64. The extremely short acquisition times of the Biograph 64 enable detailed and motion-free images of the heart. By combining both modalities into one step, the system is especially suitable for cardiovascular applications. Siemens proves once more its leading role as a developer of new hybrid imaging systems.
Hybrid systems, such as the Biograph 64, combine the functional and structural information of image generation into one system - this means generating comprehensive cardiological acquisitions in a single process during clinical routines. The special PET detectors based on lutetium oxyorthosilicate (LSO) and the new CT technologies (UEC detectors, Straton X-ray tube, z-Sharp technology, etc.) developed by Siemens allow for much shorter acquisition times with the Biograph 64 as compared to previous PET/CT systems. The additional anatomic detail information obtained due to the improved image quality provide the physician with precision diagnostic capabilities. The high-speed detector electronics Pico3D and the HI-REZ technology (high resolution) are instrumental in this effort. The Pico3D electronics greatly optimize the signal-to-noise ratio, while the HI-REZ technology improves the volumetric image resolution by 250 percent.
"A PET/CT system such as the Biograph 64 will enable a true one-stop cardiac assessment as a practical clinical routine," explained Dr. Daniel Berman, head of Cardiological Imaging and Nuclear Cardiology at the Cedars-Sinai Health System in Los Angeles, California, USA.
"The true three-dimensional nature of the modalities, providing high resolution coronary CTA (Coronary Computed Tomography Angiogram) and rest/stress perfusion and function, gives all of the imaging information a cardiologist needs for the management of most patients with coronary artery disease."
Biograph 64 uses CT technologies such as Straton and z-Sharp that were introduced for the first time with the CT system Somatom Sensation 64. At a rotation speed of up to 0.33 seconds and a spatial resolution of 0.4 mm, the technology also enables detailed imaging of large scan ranges. The physician is able to detect the smallest changes in the area displayed.
"Siemens has taken a leading role in PET/CT imaging. We see a great deal of interest on the part of our customers," explained Michael Reitermann, head of Nuclear Medicine, a division of Siemens Medical Solutions. "Today, hybrid systems have taken over more than 95 per cent of the PET market. Combined imaging provides physicians with considerably more information, facilitating diagnosis and subsequent therapeutic measures." The Biograph product family includes the Biograph 2, Biograph 6, and Biograph 16 systems. Together with the new 64 slice configuration, the company is introducing the most comprehensive and advanced product palette in hybrid imaging.
