Abstract
A method for determining physiological cardiac parameters as a function of a heart rate is provided. For at least two heart rates adjusted by a cardiac stimulation during the recording, in each case, a four-dimensional image data set of the heart showing the entire cardiac cycle is recorded using an X-ray device. The physiological cardiac parameters are determined by evaluation of the four-dimensional image data sets.
Claims24
A method for determining physiological cardiac parameters as a function of heart rate, the method comprising:
- recording, using an X-ray device, for at least two different heart rates set by cardiac stimulation during recording, a respective four-dimensional image data set of a heart comprising at least an entire cardiac cycle;
- and
- determining a physiological cardiac parameter, the determining comprising evaluating the four-dimensional image data sets.
An X-ray device comprising:
- a recording arrangement comprising:
- an X-ray emitter;
- an X-ray detector;
- and
- a control device configured to determine physiological cardiac parameters as a function of heart rate, the control device being configured for:
- recordation, using the recording arrangement, for at least two different heart rates set by cardiac stimulation during recordation, a respective four-dimensional image data set of a heart comprising at least an entire cardiac cycle;
- and
- determination of a physiological cardiac parameter, the determination of the physiological cardiac parameter comprising evaluation of the four-dimensional image data sets.
