Presented compression results performed over most medical imaging modalities including CT, MRI, nuclear medicine, ultrasound, angiogram, mammogram, digital radiograph. The results showed that the NASA technique out-performs than others, Feb., '94. Effort stopped due to industry vested interest in other techniques, June 94. It maximizes science return under a constrained communication channel capacity. The decompressed data will have some distortion, yet this technique offers the quick-look capability from a large format sensor, and allows scientists to do telescience by selecting areas of interest for further detailed observation.
Commercial application includes telemedicine, video conferences, etc.
The effort began in 1993. Analysis and simulation results helped define an algorithm that offers better image quality than the industry standard JPEG compression scheme.
