There is provided a position detection system for a medical device including a magnetic induction coil inside the medical device; a driving coil, disposed outside an operating region of the medical device, that generates induced magnetism in the magnetic induction coil; and a magnetic sensor, disposed outside the operating region, that detects the induced magnetism, wherein, when the medical device is disposed at each position in the operating region, the driving coil causes magnetism to act on the magnetic induction coil from three or more different directions, and among the three or more directions in which the magnetism acts, at least one of the directions is arranged to be a direction intersecting a plane formed by the other two directions. |
