Abstract
Embodiments provide a method for denoising time series images of a moved structure for a medical device. A movement detector detects the moved structure. The movement detector obtains a measurement of the similarity of two images that each represent the same section of the moved structure. The two images originate from two different time series images. A ratio between spatial and temporal denoising is defined for the section as a function of the measurement of the similarity.
Claims20
A method for denoising a plurality of time series images of a moved structure for a medical device, the method comprising:
- detecting, by a movement detector, the moved structure;
- obtaining, by the movement detector, a measurement of a similarity of two images, each of the two images representing a same section of the moved structure, wherein the two images originate from two different time series images of the plurality of time series images;
- and
- defining a ratio between a spatial and a temporal denoising for the section as a function of the measurement of the similarity.
An apparatus for denoising time series images of a moved structure for a medical device, the apparatus comprising:
- a denoising device;
- and
- a movement detector configured to:
- detect the moved structure;
- obtain a measurement of a similarity of two images, each of the two images representing a same section of the moved structure, wherein the two images originate from two different time series images;
- and
- define a ratio between a spatial denoising and a temporal denoising for the denoising device as a function of the measurement.
