| NVIDIA Graphics Power Cancer-Detection Solution NVIDIA Corporation has announced that a cancer-detection system developed by Massachusetts General Hospital and Mercury Computer Systems has been recognized by Advanced Imaging Magazine with an "Imaging Solutions of the Year" award. NVIDIA Quadro FX professional graphics solutions provide the processing power for the computationally-intense system. Award winners were chosen based on the uniqueness of the challenge as well as on the creativity of their solution. Categories covered the spectrum - from industrial and machine vision through space imaging and image visualization to medical, microscopy, military and commercial applications. Massachusetts General Hospital developed the Digital Breast Tomosynthesis (DBT) imaging system and Mercury Computer Systems developed a high speed solution to permit rapid processing of the images. NVIDIA Quadro FX includes a unique programmable rendering pipeline that enables the reconstruction of a 3D volume from a series of 2D projection images. Components of the system also include the Senographe 2000 Digital Mammography System from GE Healthcare and an advanced "likelihood expectation" algorithm co-developed by Brandeis University and Massachusetts General Hospital. The project was supported in part by two grants from the US Army Medical Research and Material Command. DBT provides the advantage of enabling physicians to "page through" the interior of the breast without obstruction by surrounding superimposed tissue. In the past, the potential benefits of DBT were downplayed because the method was computationally intense and took far too long for use in a clinical setting. With the new system, computation time was reduced from five hours to five minutes, a 60x performance increase. In pre-clinical testing, the new DBT system permitted physicians to find cancers earlier and more easily, and to differentiate benign versus malignant lesions while simultaneously reducing false positives.
