Continuous operation method for a tomography device and corresponding tomography device

A method for operating a tomography apparatus comprising the steps of:

• positioning a first examination subject relative to a rotatable tomographic scanning unit;
• conducting a tomography examination of said first examination subject by rotating said scanning unit relative to said first examination subject to acquire tomography data from the first examination subject, at a rotation frequency selected, dependent on a type of said examination of said first examination subject, from among a plurality of different rotation frequencies;
• removing said first examination subject from said scanning unit and positioning a second examination subject relative to said scanning unit;
• conducting a tomography examination of said second examination subject by rotating said scanning unit relative to said second examination subject, to acquire tomography data from the second examination subject, at a rotation frequency, selected, dependent on a type of said examination of said second subject, from among said plurality of rotation frequencies;
• and
• rotating said scanning unit without interruption from a beginning of said examination of said first examination subject through an end of said examination of said second examination subject and, when neither of said first or second examination subjects is positioned relative to said scanning unit, rotating said scanning unit at a rest frequency selected from the group consisting of a rotation frequency that is smaller than a smallest of said plurality of rotation frequencies, and a rotation frequency that is an average of said plurality of rotation frequencies.

A tomography apparatus comprising:

• a rotatable scanning unit for acquiring tomographic data;
• a bearing device for positioning a first examination subject relative to said scanning unit and for subsequently removing said first examination subject from said scanning unit and positioning a second examination subject relative to said scanning unit;
• a control unit for operating said scanning unit to conduct a tomography examination of said first examination subject by rotating said scanning unit relative to said first examination subject to acquire tomography data from the first examination subject, at a rotation frequency selected, dependent on a type of said examination of said first examination subject, from among a plurality of different rotation frequencies, and to conduct a tomography examination of said second examination subject by rotating said scanning unit relative to said second examination subject to acquire tomography data from the second examination subject, at a rotation frequency, selected, dependent on a type of said examination of said second subject, from among said plurality of rotation frequencies, while rotating said scanning unit without interruption from a beginning of said examination of said first examination subject through an end of said examination of said second examination subject and, when neither of said first or second examination subjects is positioned relative to said scanning unit, rotating said scanning unit at a rest frequency selected from the group consisting of a rotation frequency that is smaller than a smallest of said plurality of rotation frequencies, and a rotation frequency that is an average of said plurality of rotation frequencies.
