Real-time imaging is useful for many diagnostic and interventional procedures. While the most basic morphological imaging techniques are adequate in many cases, there is an increasing need for more sophisticated imaging sequences. Spectral decomposition techniques like IDEAL would be used to image a ceramic biopsy trocar in fatty areas of the breast, or for monitoring the delivery of therapeutic agents tagged with lipid or SPIO markers. By eliminating closely coupled and vendor specific integration between the image processing layers, the development and deployment of new imaging techniques is simplified and accelerated. We present an implementation of IDEAL on the HeartVista RTHawk real-time imaging platform, showing phantom studies for both a Cartesian and spiral acquisition, with per-frame imaging time on the order of seconds.
