Abstract
A method to process radiological images is provided. The method comprises partitioning a radiological image of a region to be treated into a superimposition of layers, the region to be treated comprising at least one first structure and a second structure, wherein one layer solely comprises part of the first structure to be isolated from the remainder of the image, the layer solely comprising that part of the first structure to be isolated from the remainder of the image being determined by means of a parametric model of the first structure. The method further comprises determining an image of the region to be treated from the layering thus obtained, in which the isolated part of the first structure is omitted.
Claims9
A method to process radiological images, the method comprising:
- partitioning a radiological image of a region to be treated into a superimposition of layers, the region to be treated comprising at least one first structure and a second structure,
- wherein the first structure is an instrument and wherein the second structure is a vascular prosthesis and the structures associated with a vessel,
- wherein one layer solely comprises part of the first structure to be isolated from the remainder of the image, the layer solely comprising that part of the first structure to be isolated from the remainder of the image being determined by means of a parametric model of the first structure, wherein the parametric model of the first structure is at least a function of a distance to a central line or to a centre of the first structure;
- and
- determining an image of the region to be treated from the layering thus obtained, in which the isolated part of the first structure is omitted.
A medical imaging system comprising:
- a source configured to emit a beam of rays;
- a detector positioned facing the source and configured to detect the rays emitted by the source;
- a support positioned between the source and the detector;
- a storage unit;
- an interface unit;
- and
- a processing unit configured to:
- partition a radiological image of a region to be treated into a superimposition of layers, the region to be treated comprising at least one first structure and a second structure,
- wherein the first structure is an instrument and wherein the second structure is a vascular prosthesis and the structures associated with a vessel,
- wherein one layer solely comprises part of the first structure to be isolated from the remainder of the image, the layer solely comprising that part of the first structure to be isolated from the remainder of the image being determined by means of a parametric model of the first structure, wherein the parametric model of the first structure is at least a function of a distance to a central line or to a centre of the first structure;
- and
- determine an image of the region to be treated from the layering thus obtained, in which the isolated part of the first structure is omitted.
