MULTI-PURPOSE ROBOTIC SYSTEM FOR MRI GUIDED FOCUSED ULTRASOUND TREATMENT

摘要

The current invention relates to an MRI compatible positioning system which is capable of carrying a FUS transducer 41 in order to treat diseases of the fibroid, abdominal, breast and brain. The positioning system employs only MRI compatible materials such as piezoelectric motors 33, 22, 10 and ABS plastic. The robotic system moves the transducer in 4 axes. The rotational motion of the piezoelectric motors is coupled to a jack screw gear mechanism. The positioning device is placed on the table of the MRI scanner and access of ultrasound to the abdominal, breast and brain is achieved from bottom to top. Sideway access to the brain is also possible. For fibroid the coupling can be a top to bottom approach. Top to bottom coupling can be applied also for breast. This is the first system that provides access to targets top to bottom, bottom to top and sideways.
