Abstract
The invention provides methods and systems for correcting translational distortion in a medical image of a lumen of a biological structure. The method facilitates vessel visualization in intravascular images (e.g. IVUS, OCT) used to evaluate the cardiovascular health of a patient. Using the methods and systems described herein it is simpler for a provider to evaluate vascular imaging data, which is typically distorted due to cardiac vessel-catheter motion while the image was acquired.
Claims20
A system for transforming an image of a lumen, comprising:
- a processor;
- and
- storage coupled to the processor, the storage comprising instructions that when executed cause the processor to:
- receive data corresponding to a first image of a lumen;
- register coordinates of at least two points in the first image of the lumen;
- receive data corresponding to a second image of a lumen;
- register coordinates of at least two points in the second image of the lumen;
- compare the coordinates of the at least two points in the first image of the lumen to the coordinates of the at least two points in the second image of the lumen;
- determine a translation to align the at least two points in the first image of the lumen and the at least two points in the second image of the lumen;
- and
- translate the first image or the second image of the lumen to align the at least two points in the first image of the lumen and the at least two points in the second image of the lumen.

- determine a translation to align the at least two points in the first image of the lumen, the at least two points in the second image of the lumen, and the at least two points in the third image of the lumen;
- and
- translate the first image to align the at least two points in the first image of the lumen, the at least two points in the second image of the lumen, and the at least two points in the third image of the lumen.
