<P>PROBLEM TO BE SOLVED: To solve a technical problem of automatic collimation by making simple a flow of automatic collimation by a medical apparatus, and to improve the experience of a patient. <P>SOLUTION: A collimation system for a medical apparatus includes a medical apparatus body and a collimation member. The medical apparatus includes a moving member which moves to a target position for making a diagnosis or performing a treatment, and the collimation member includes a laser emitting device, a photographing device, and a computing device. The laser emitting device emits a laser to irradiate a target of a body surface of the patient with the laser. The photographing device photographs the laser irradiation spot. The computing device obtains the position of the laser irradiation spot by performing a computation on images acquired by the photographing device. The medical apparatus automatically positions the moving member based on the position of the irradiation spot obtained by the computation. The acquisition frequency of the photographing device is twice the frequency of laser pulses, and the contour computation is performed on two adjacent images to obtain the position of the laser irradiation spot. <P>COPYRIGHT: (C)2012,JPO&INPIT |
