TESTER AND ANGLE ADJUSTMENT APPARATUS

PROBLEM TO BE SOLVED: To conduct an angular resolution test of a nonimage intraoperative gamma probe at an angle of at least ±90° to the vertical direction. SOLUTION: In the embodiment shown in the description, an arm for supporting a probe holding tool is formed into a S-shape (or a reverse S-shape) when it is downwardly viewed in the vertical direction. The arm is extended from a supporting post turnably attached to a base of a probe holding apparatus. A liquid tank for immersing a radiation source is separately prepared. A frame wall of the liquid tank faces the supporting post, and has a shape in which either left or right side approaches the supporting post. COPYRIGHT: (C)2009,JPO&INPIT
