Abstract
We have started clinical studies of MR-guided thermocoagulation therapy of liver tumors. Through this therapy for two years, we have developed new instruments, such as a filter to reduce noise in MRI from the microwave coagulator, a new MR-compatible electrode for easy detection of the tip position and an MR-compatible endoscopic system for trans-diaphragmatic approach to liver tumors just below the diaphragm. Concerning software, a program was modified for the real-time display of MR temperature map with a scale bar. A navigation software, 3D Slicer was customized to add real-time image navigation capability. The re-sliced images in the two perpendicular planes complemented the limitations of real-time MR image, which is taken in 2–3 seconds. These technical developments play important roles for more accurate, safer and easier treatment.
