Abstract: This invention relates generally to the detection of objects, such as stents, within intraluminal images using principal component analysis and/or regional covariance descriptors. In certain aspects, a training set of pre-defined intraluminal images known to contain an object is generated. The principal components of the training set can be calculated in order to form an object space. An unknown input intraluminal image can be obtained and projected onto the object space. From the projection, the object can be detected within the input intraluminal image. In another embodiment, a covariance matrix is formed for each pre-defined intraluminal image known to contain an object. An unknown input intraluminal image is obtained and a covariance matrix is computed for the input intraluminal image. The covariances of the input image and each image of the training set are compared in order to detect the presence of the object within the input intraluminal image.

Abstract: This invention relates generally to methods and systems for removing an artifact within an image. Typically, the artifact is a guidewire artifact. In one aspect, at least two images of an imaging surface are acquired. Each acquired image comprises a set of data. A guidewire artifact is detected in one of the at least two images. The guidewire artifact is replaced with data representing the imaging surface obtained from another one of the at least two images. In certain embodiments, the at least two images are of the same imaging surface having a guidewire or object causing the artifact moved to a different position.

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.
