Abstract
It is intended to implement imaging in an efficient way. In a first period in which a cradle unit is driven under acceleration from a stationary state, the cradle unit is driven with a constant first torque value. In a second period which comes after the lapse of the first period and in which the cradle unit is driven under acceleration, the cradle unit is driven with a constant second torque value which is smaller than the first torque value.
Claims15
An imaging apparatus for imaging a subject in an image pickup space, comprising:
- a cradle unit for supporting said subject;
- and
- a cradle driving unit for driving said cradle unit into said image pickup space, with a constant first torque value during a first period in which said cradle unit is driven under acceleration from a stationary state, and with a constant second torque value which is smaller than said first torque value during a second period which is after the lapse of said first period and in which said cradle unit is driven under acceleration.
A subject moving apparatus for moving a subject, comprising:
- a cradle unit for supporting said subject;
- and
- a cradle driving unit for driving said cradle unit with a constant first torque value during a first period in which said cradle unit is driven under acceleration from a stationary state, and with a constant second torque value which is smaller than said first torque value during a second period which is after the lapse of said first period and in which said cradle unit is driven under acceleration, said first torque value calculated based on a maximum frictional force which arises when said cradle unit is driven into an image pickup space.
A subject moving apparatus for moving a subject, comprising:
- a cradle unit for supporting the subject;
- and
- a cradle driving unit for driving said cradle unit with a constant first torque value during a first period in which said cradle unit is driven under acceleration from a stationary state, and with a constant second torque value which is smaller than said first torque value during a second period which is after the lapse of said first period and in which said cradle unit is driven under acceleration, said cradle driving unit drives said cradle unit using a torque value corresponding to a driving force in excess of 200 N as said first torque value during said first period so as to move not more than 10 mm, and a torque value corresponding to a driving force of not greater than 200 N as said second torque value during said second period.
An imaging apparatus for imaging a subject in an image pickup space, comprising:
- a scanning gantry unit for acquiring raw data on said subject in said image pickup space by scanning said subject;
- and
- a scanning gantry driving unit for driving said scanning gantry unit so as to accommodate said subject in said image pickup space, with a constant first torque value during a first period in which said scanning gantry unit is driven under acceleration from a stationary state, and with a constant second torque value which is smaller than said first torque value during a second period which is after the lapse of said first period and in which said scanning gantry unit is driven under acceleration.
