PHANTOM FOR IRRADIATION ANGLE MEASUREMENT AND IRRADIATION ANGLE MEASUREMENT METHOD AND STEREOSCOPIC IMAGE ACQUISITION METHOD USING SAID PHANTOM

摘要

[Problem] To acquire the actual imaging angles during stereoscopic imaging with high precision. [Solution] A phantom (6) for irradiation angle measurement is configured from a three-dimensional structure (60) obtained from a material having a first transmittance with respect to radiation irradiated from a prescribed direction and at least two markers (61, 62) obtained from a material having a second transmittance, which differs from the first transmittance, and provided at mutually differing positions in the direction orthogonal to the opposing surfaces (60a, 60b) of the three-dimensional structure (60). The irradiation angle is acquired using said irradiation angle measurement phantom (6).
