PROBLEM TO BE SOLVED: To provide a current source simulator existing at various depths and positions to easily and correctly obtain test data for a current source. SOLUTION: A current supplied from a current drive control device 16 to go through a vertical part 22g of a coated wire to reach a horizontal part 21a becomes a current 25a uniformly distributed in the horizontal part 21 to flow to reach a tip part 23a, it becomes a feedback current 29 in physiological salt solution to go through a tip part 23b of a horizontal part 21b on the other side to become a current 25b uniformly distributed in the horizontal part 21b again, and it flows through the vertical part 22b to return to the current control device 16. Position adjustment of a current dipole 14 can be easily performed in a phantom 12 by moving a support pipe 13 as a drop-proof connector 15 is a little loosened, and then tightening the drop-proof connector 15 again. |
