1. Planning, which among other things, requires accu-
rate identi?cation
of the location and spatial extent of
the pathology to be treated,
2. guidance, which in addition to 1., requires accurate
prediction of
the location and spatial extent of the
thermal lesion before its
formation,
3. treatment monitoring, which requires the ability to
image with high
contrast the location and extent of
regions of ablated tissue,
4. monitoring of response, which among other things,
requires the
ability to observe changes in tissue ar-
chitecture and blood ?ow due to
tissue healing.
