Publication number: 20240252117Abstract: A magnetic resonance imaging apparatus according to an embodiment includes a table apparatus and a processor. The table apparatus includes a table-top on which a subject is placed. The processor acquires subject position information indicating a position of the subject on the table-top. The processor acquires weight information indicating a weight of the subject. The processor calculates an amount of deflection occurred in the table-top based on the subject position information and the weight information. The processor generates, based on the amount of deflection of the table-top, first path information indicating a path along which the table-top is moved from the table apparatus to a gantry where imaging of the subject is performed. The processor operates a moving mechanism capable of moving the table-top from the table apparatus to the gantry to move the table-top from the table apparatus to the gantry along the path indicated by the first path information.Type: ApplicationFiled: January 5, 2024Publication date: August 1, 2024Applicant: CANON MEDICAL SYSTEMS CORPORATIONInventors: Keisuke OKUZUMI, Kaoru IKEDA, Naoko YAMAGUCHI, Shoji ISHIZAKI
