Abstract
In a method and apparatus for acquiring cardiac image data of a subject of examination, in particular in the context of magnetic resonance tomography, a first image acquiring technique is implemented, in which image data acquiring takes place only in a part of the cardiac cycle, and/or not in each cardiac cycle, and a second image acquiring technique is alternatingly implemented, such that the image data acquiring using the second image acquiring technique takes place at times in which image data acquiring using the first image acquiring technique is not occurring.
Claims17
A method for acquiring cardiac image data from an examination subject, comprising the steps of:
- interacting with an examination subject using a non-ciné first image acquisition technique, selected from the group consisting of image techniques that obtain a morphological image of the examination subject and techniques that obtain a functional image of the examination subject, to acquire cardiac image data forming a first tomogram only during a portion of a cardiac cycle, and/or not in every cardiac cycle;
- in alternation with said first image acquisition technique, interacting with the examination subject with a second image acquisition technique, that is a ciné technique, to acquire cardiac image data forming a second tomogram at times in which image data acquisition using the first image acquisition technique is not occurring;
- and
- acquiring said image data forming said first tomogram with a slice position, and acquiring said image data forming said second tomogram with the same slice positioning.
A medical imaging apparatus comprising:
- an imaging system adapted to interact with an examination subject to acquire tomographic image data therefrom;
- and
- a control unit that controls said medical imaging system to acquire said tomographic image data from the examination subject by operating said medical imaging system with a non-ciné first image acquisition technique, selected from the group consisting of image techniques that obtain a morphological image of the examination subject and techniques that obtain a functional image of the examination subject, to acquire cardiac tomographic image data forming a first tomogram only in a subpart of a cardiac cycle of the examination subject, and/or not in every cardiac cycle of the examination subject, and by operating said medical imaging system with a second image acquisition technique, that is a ciné technique, in alternation with said first image acquisition technique, to acquire cardiac tomographic image data forming a second tomogram at times in which acquisition of tomographic image data is not occurring in said first image acquisition technique;
- and
- said control unit causing said image data forming said first tomogram to be acquired with a slice positioning, and causing said image data forming said second tomogram to be acquired with the same slice positioning.
