Technology Overview PET TREATMENT PET Treatment continued from page 21 One of the buzzwords today in imaging is high-definition (HD). But beyond the hype, there are significant benefits that HD lends image quality; enough for Siemens Healthcare to introduce its latest PET/CT system, Biograph mCT, which includes advanced HD to create a new system that is capable of scanning the whole body in five minutes and allows for low dose scans. “High-definition PET enables improved delineation of small and early lesions, especially lesions without very high tracer uptake due to the improved resolution and higher lesion contrast obtained by HD and ultraHD technology,” said Partha Ghosh, M.D., clinical marketing manager, molecular imaging, Siemens Healthcare. “Thus patients with small metastases, early tumor recurrence especially in regions with distorted anatomy following surgery or radiotherapy and metastases with lower tumor burden causing it to have low FDG uptake are better visualized with HD and ultraHD technology.” UltraHD technology combines time-of-flight (TOF) and point-spread-function (PSF) reconstruction and offers 2-mm uniform resolution throughout the entire field of view (FOV) and 4 times enhanced lesion contrast compared to standard PET scans. He added, “This should help early diagnosis of metastases and tumor recurrence and evaluation of treatment follow up since visualization of small residual disease would otherwise be missed and would have a major impact on further treatment decision.” According to Siemens, with Biograph mCT, a facility may only need to pur- chase one imager instead of two, representing a huge cost-savings potential in a time when healthcare budgets are tight. With oncology applications representing more than 90 percent of clinical PET/CT exams, GE Healthcare integrated its BrightSpeed CT with the motion management capabilities of its Discovery PET system to create the Discovery PET/CT 600. The system is optimized for use in oncology and is capable of managing and correcting for motion during a scan. As a key component of the image chain, the Discovery PET/CT 600 includes a scintillator with high sensitivity level available, and GE BGO technology said to allow for improved lesion detectability, potentially reducing the dose requirement and allowing for faster scans and increased throughput. As new technology continues to enhance the image quality of PET/CT, and studies demonstrate the clinical efficacy of the system, the medical community is building its case for why Medicare should expand reimbursement for PET, and so far, it is a convincing one.

U.S. Electronics Launches 6-Mega Independent Subpixels Grayscale LCD U.S. Electronics Inc.’s new 21.3-inch 6-mega independent subpixel drive (ISD) grayscale medical display MS21i2 is a high-resolution display utilizing independent subpixel drive technology. The MS21i2 achieves 1276-step simultaneously displayable grayscale palette by using enhanced ISD technology enabling more accurate display images. Also, this model has advanced luminance control. By utilizing the subpixel drive technology, MS21i2 provides comparatively the same resolution as a 6 MP display, without the extra costs typically associated with higher resolution displays. This model is reportedly ideal for CT, MRI, CR and X-ray. U.S. Electronics Inc. www.us-electronics.com Medvix Unveils New Series of Surgical LCD Displays Medvix recently launched its AMVX Series 15-inch, 19-inch, 21-inch, 24-inch, 32-inch, 37-inch and 42-inch LCD displays at the AMVX Series. The AMVX Series reportedly produces a crisp, clear and consistent color image with a wide viewing angle helping improve patient outcomes and OR productivity. Each panel features multiple inputs such as analog, digital DVI, composite and S-video input.
