HEAT SURGERY SYSTEM MONITORED BY REAL-TIME MAGNETIC RESONANCE PROFILING |
摘要 |
<p>Surgery is performed with a pulsed heat-producing means that selectively heats a region in a specific tissue within a patient destroying the tissue. The pulsed heat-producting means may be a coherent optical source that is guided by laser fiber to the tissue to be destroyed. In another embodiment, the pulsed heat-producing means is a focussed ultrasound transducer which concentrates ultrasonic energy at a focal point within the specific tissue. A magnetic resonance imaging system employing a real-time temperature-sensitive pulse sequence monitors the heated region of the tissue to provide temperature profiles allowing an operator to alter the position and size of the heated region.</p> |
