We
have developed an integrated MRI and high intensity focused ultrasound (HIFU)
real time system. The system allows
for both flexible control and monitoring of both systems, from device
localization utilizing MR tracking to treatment planning and therapy
monitoring utilizing MR thermometry pulse sequences. Additionally, the software allows for
prescription of complex sonication spots, including treatment paths and
regions. The system was tested both in
a phantom and in vivo to assess its effectiveness in guiding HIFU therapy. Prescribed treatment plans were achieved in
both experiments.
