Yes and no. Placement is a gross position thing; you simply use a radiography guided needle to place the probe in roughly the center of the tumor. The positioning comes into play when actual radiotherapy is used. It relays positional information (similar to GPS theory) back to the computers, allowing for precision use of radiation.
