<p>A system and process for monitoring a targeted area of a patient's body to precisely locate the targeted area in real-time are provided. The system includes at least one datum device to be placed a predetemined distance from the targeted area, either on or within the body. The system also includes means for sensing the at least one datum device, means for determining a real-time position of the at least one datum device, and means for calculating changes in the position of the datum device in real-time. Any changes in the position of the datum device are conveyed to a radiotherapy device which emits a radiation beam directed at the targeted area. The radiation beam is controlled according to changes in the position of the datum device in order to maintain precise targeting on the area to be treated.</p> |
