Abstract
A method is for determining a vessel puncture position including reception of a first image dataset of a region of interest via an interface, the first image dataset mapping the vessel. The method further includes determination of a vessel line of the vessel based on the first image dataset via a computing unit. The method further includes determination of a gradient measure based on the vessel line. Finally, the method includes a determination of the vessel puncture position based on the gradient measure. A position-determining unit, a computer program product and a computer-readable storage medium are for determining a vessel puncture position.
Claims27
A method for determining a vessel puncture position of a vessel, comprising:
- receiving, via an interface, a first image dataset of a region of interest, the first image dataset mapping the vessel;
- determining, via at least one processor, a vessel line of the vessel based on the first image dataset received;
- determining, via the at least one processor, a gradient measure of the vessel line determined;
- and
- determining, via the at least one processor, the vessel puncture position of the vessel based on the gradient measure determined, wherein the puncture position designates a point in the first image dataset describing a probable location at which a catheter penetrates the vessel.
A position-determining unit for determining a puncture position of a vessel, comprising:
- interface, embodied to receive a first image dataset of a region of interest, the first image dataset mapping the vessel;
- and
- at least one processor, embodied to
- determine a vessel line of the vessel based on the first image dataset received,
- determine a gradient measure of the vessel line determined, and
- determine the puncture position based on the gradient measure determined, wherein the puncture position designates a point in the first image dataset describing a probably location at which a catheter penetrates the vessel.
A position-determining unit for determining a puncture position of a vessel, comprising:
- interface, embodied to receive a first image dataset of a region of interest, the first image dataset mapping the vessel;
- and
- at least one processor, embodied to
- determine a projected vessel line of the vessel by projection of a vessel line along a first direction, the vessel line being based on the first image dataset received,
- determine a gradient measure of the projected vessel line determined, with respect to a second direction, the second direction being orthogonal to the first direction, and
- determine the puncture position based on the gradient measure determined, wherein the puncture position designates a point in the first image dataset describing a probably location at which a catheter penetrates the vessel.
