Mercury shows new applications for Visage 3D
Mercury Computer Systems showcased at RSNA 2006 its Visage 3D to the Core product line with advanced functionalities, new clinical applications, and improved levels of image quality and performance. Featured products included Mercury’s Visage MR, the Visage CS Thin/Client Server, Visage RT and the Cell Accelerator Board.                       
Mercury’s Visage MR Digital MRI Receiver features high-speed and high-resolution analog-to-digital conversion combined with advanced filtering and noise-reduction technology. The single-board multi-channel receiver includes software that can be combined with multiple boards in parallel, scaling acquisition channel capability to significantly reduce scan times in anatomical imaging – especially in 3D applications. The ExactPhase digital detection method (DDM) enables parallel acquisition with a zero-phase distortion, thereby reducing ghosting and ringing artifacts, Mercury said.

Visage MR has four times the resolution of current-generation MRI receivers coupled with an extremely high sampling rate. The combination extends dynamic range through decimation to 24 bits of resolution, preserving more of the MRI signal to allow the visualization of finer image detail while speeding fast MRI imaging sequences, the company said.

Mercury’s Visage CS Thin Client/Server offers advanced 3D medical workstation capabilities on thin clients anytime, anywhere throughout the hospital enterprise. Visage CS allows laptops and standard PCs to act as fully functional medical workstations, enabling fast and easy-to-use 3D reading and post-processing with efficient and consistent data access. All medical image data processing and visualization are done on a central server, and only the resulting screen content is streamed to the thin client via a standard network connection. Mercury said it was recently granted clearance by the FDA to market Visage CS as a medical device in the United States.

Visage RT image reconstruction software provides embedded components for accelerated reconstruction of image volumes from a broad range of scanning modalities including CT, MR, x-ray, SPECT, PET, ultrasound, electron tomography (SEM/TEM), and digital breast tomosynthesis (DBT). Visage RT leverages commodity graphics processors such as GPUs and the Cell Broadband Engine processor to accelerate the image reconstruction process by orders of magnitude.

In addition, Mercury highlighted the Cell Accelerator Board (CAB) that is a PCI Express accelerator card based on the Cell Broadband Engine processor. The technology offers faster processing for graphics, image, and signal processing workloads.
