Abstract
A method and a tomography unit are disclosed for taking tomographic pictures of a patient's beating heart, in particular X-ray CT pictures. In such a method and tomography unit, only detector data or image data of a portion of the cardiac phase from one or more heart beats is used for taking a picture. Further, at least one pressure signal, produced by the mechanical cardiac pulse and varying temporally with the cardiac cycle, is used for determining the cardiac phase.
Claims26
A method for taking a tomographic picture of a patient's beating heart, comprising:
- taking a tomographic picture using only data of a portion of a cardiac phase from at least one heart beat, at least one pressure signal, produced by a mechanical cardiac pulse and varying temporally with the cardiac cycle, being used for determining the cardiac phase.
A tomography unit for taking a tomographic picture of a patient's beating heart, comprising:
- means for scanning a patient;
- means for reconstructing three-dimensional pictures from detector data of a portion of a cardiac phase from one or more heart beats;
- and
- means for pressure pulse detection, connected to the means for reconstructing three-dimensional pictures of the beating heart, the cardiac phase being calculated from the pressure pulse.
The method as claimed in 1, wherein the tomographic picture is an X-ray CT picture.
A method for taking a tomographic picture of a patient's beating heart, comprising:
- using at least one pressure signal, produced by a mechanical cardiac pulse and varying temporally with the cardiac cycle, for determining a cardiac phase;
- and
- taking a tomographic picture using only detector data or image data of a portion of the cardiac phase from one or more heart beats.
The method as claimed in 20, wherein the tomographic picture is an X-ray CT picture.
