Medical device, table driving method, and recording medium

A method of driving a table on which a subject is placed and for each examination of the subject, executing:

• driving the table based on an offset for correcting a table height positional offset to position an imaging location of the subject at a prescribed table height position,
• determining a center of gravity of the imaging location of the subject in a height direction of the table based on a medical image of the imaging location of the subject,
• calculating a difference between a prescribed position and a center of gravity as positional deviation of the table height, and storing the positional deviation;
• the method of driving the table further comprising:
• obtaining a representative value indicating characteristics of a positional deviation distribution;
• determining whether the representative value of the positional deviation is statistically reliable,
• updating the offset based on the representative value if the representative value is determined to be statistically reliable, and
• driving, in response to input from an operator, the table based on the updated offset or drive the table based on the offset prior to updating.

A storing device, comprising:

• a non-transitory computer-readable recording medium having stored thereon one or more instructions executable by at least one processor, and when executed by the at least one processor each time an examination of a subject is executed, the one or more instructions for executing operations include:
• driving a table using a table controller for controlling the table based on an offset for correcting a table height positional offset to enable positioning an imaging location of the subject at a prescribed table height position,
• determining a center of gravity of the imaging location of the subject in a height direction of the table based on a medical image of the imaging location of the subject,
• calculating a difference between a prescribed position and the center of gravity as positional deviation of table height, and
• storing the positional deviation;
• and
• when executed by the at least one processor, the one or more instructions for executing operations further include:
• obtaining a representative value representing characteristics of a positional deviation distribution,
• determining whether the representative value of the positional deviation is statistically reliable,
• updating the offset based on the representative value if the representative value is determined to be statistically reliable, and
• driving, in response to input from an operator, the table based on the updated offset or drive the table based on the offset prior to updating.
