Abstract
Systems and methods are described for the compositing together of model-linked vascular data from a plurality of sources, including at least one 2-D angiography image, for display in a frame of reference of the at least one angiography image. In some embodiments, a linking model comprises a data structure configured to link locations of angiographic images to corresponding elements of non-image vascular parameter data. The linking data structure is traversed to obtain a mapping to the frame of reference of one or more of the angiographic images.
Claims27
A method for displaying vascular parameter data, the method comprising:
- receiving, in a processor, a first 2-D angiographic image recorded at a first angle with respect to a patient containing a first image representation of the patient's coronary arteries and a second 2-D angiographic image recorded at a second angle with respect to the patient containing a second image representation of the patient's coronary arteries, the second angle being at least 30° different from the first angle;
- creating, via the processor, a first data structure including first coordinates that are indicative of vascular locations of the patient's coronary arteries in the first 2-D angiographic image and a second data structure including second coordinates that are indicative of the vascular locations of the patient's coronary arteries in the second 2-D angiographic image;
- creating, via the processor, a third data structure including identifiers that are each representative of the vascular locations along the patient's coronary arteries, each identifier being linked to a coordinate of the first coordinates and a corresponding coordinate of the second coordinates that correspond to a same vascular location of the patient's coronary arteries;
- creating, via the processor, a fourth data structure including vascular parameter data that is linked to corresponding identifiers of the third data structure based on locations of the identifiers corresponding to the vascular locations of the patient's coronary arteries;
- determining, via the processor, the vascular locations where at least some of the vascular parameter data is to be displayed in relation to the first 2-D angiographic image using the identifiers in the third data structure that link the vascular parameter data to the first coordinates;
- and
- displaying via the processor, the first 2-D angiographic image and the at least some of the vascular parameter data such that the at least some of the vascular parameter data is displayed in proximity to a corresponding vascular location of the patient's coronary arteries shown in the first 2-D angiographic image.

An apparatus for display of vascular parameters for vascular assessment, the apparatus comprising:
- a memory device storing:
- a first angiographic image recorded at a first angle with respect to a patient containing a first image representation of the patient's coronary arteries,
- a second angiographic image recorded at a second angle with respect to the patient containing a second image representation of the patient's coronary arteries, the second angle being at least 30° different from the first angle,
- a first data structure including first coordinates that are indicative of vascular locations of the patient's coronary arteries in the first angiographic image,
- a second data structure including second coordinates that are indicative of the vascular locations of the patient's coronary arteries in the second angiographic image,
- a third data structure including identifiers that are each representative of the vascular locations along the patient's coronary arteries, each identifier being linked to a coordinate of the first coordinates and a corresponding coordinate of the second coordinates that correspond to a same vascular location of the patient's coronary arteries, and
- a fourth data structure including vascular parameter data that is linked to corresponding identifiers of the third data structure based on locations of the identifiers-along corresponding to the vascular locations of the patient's coronary arteries;
- and
- a processor communicatively coupled to a memory device, the processor configured to:
- determine vascular locations where at least some of the vascular parameter data is to be displayed in relation to the first angiographic image using the identifiers in the third data structure that link the vascular parameter data to the first coordinates, and
- cause the first angiographic image and the at least some of the vascular parameter data to be displayed such that the at least some of the vascular parameter data is displayed in proximity to a corresponding vascular location of the patient's coronary arteries shown in the first angiographic image.
