Title:
IRRADIATION APPARATUS FOR THERAPY OF SELECTED AREA USING RADIATION ENERGY BEAM AND METHOD THEREFOR
Document Type and Number:
Japanese Patent JPH02289271
Kind Code:
A
Abstract:
PURPOSE: To ensure a stereotaxic and a patient's accurate diagnostic zone by providing a means to fix a blocking member to a scanner so as to let it pass the part where the radiant energy flux is not attenuated in order for a pre-determined zone to be radiated and to put a blocking member in the radiant energy flux between a radiant energy flux source and the pre-determined zone. CONSTITUTION: This device is equipped with a blocking member 10 to be fixed to a detachable scanner. The following is the preferable means: it can maintain a blocking member in a pre-determined relation with a radiant energy flux and at the same time can be detachable by a screw, clip, fastener, snap or the like from the blocking member when it is required for contrast sake, to be replaced for a new blocking member or to be removed. The blocking member is put in the radiant energy flux between a radiant energy flux source 30 and a pre-determined target zone 22. Thus, the location of a blocking member can be determined so the pre-determined zone can be irradiated by letting the part 14 which is not attenuated of the radiant energy flux 16, pass the interval 12.
