Functional cardiac imaging methods are important diagnostic tools in the evaluation of heart disease. Conventional methods of imaging are limited in their accuracy and may involve the use of ionizing radiation. Magnetic Resonance Imaging (MRI) is a non-invasive high quality imaging technique. MR images of cardiac function can now be routinely acquired, however it is current practice to perform qualitative interpretation only. Quantitative analysis has been limited by the lack of affordable, robust, systems for automatic processing and analysis of the images in a clinically acceptable time frame, that is, while the patient remains in the scanner. Quantitative analysis of images will increase diagnostic confidence resulting in improved patient care and ultimately lower costs.
Such productivity improvements can be achieved, at a reasonable cost, through the application of High Performance Computing and Networking (HPCN) techniques to the processing of scanner data using existing, but computationally demanding algorithms. These algorithms allow quantitative diagnostic analysis; for example the volume of blood pumped by the heart can be quantitatively estimated.
CAMRA (Cardiac Magnetic Resonance Analysis) demonstrates high performance, low cost analysis of cardiac MR images on multi-processor PC-compatible systems running under Windows NT. CAMRA increases the performance of the ANALYZE biomedical image analysis package by parallelizing existing serial algorithms. This will allow a shift in clinical diagnosis from qualitative to quantitative interpretation of images with resultant improvements in patient care.
