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.
