At the Department of Medical Physics at the University of Wisconsin-Madison, research on dual energy chest imaging including the algorithm and patient studies is done using a Pixar image processor computer. In the project described here, a study was made of which low-cost system is able to replace the Pixar and provide high-speed dual energy image processing. The dual energy algorithm was analyzed and the user and system requirements were obtained. A single workstation (e.g. Sun Sparc Station 2) does not provide enough processing power. Therefore accelerator boards for the workstation were reviewed. A prototype system was developed, using an i860-based accelerator board, i.e. the CSPI SuperCard-1, in a Sun 3/150 host computer. Bare computer time for the dual energy algorithm was reduced from 25 min using the Pixar image computer to less than three minutes using the SuperCard-1 processor board
