Abstract: Systems and methods for aiding users in viewing, assessing and analyzing images, especially images of lumens and medical devices contained within the lumens. Systems and methods for interacting with images of lumens and medical devices, for example through a graphical user interface.

Abstract: The invention generally relates to medical imaging systems that instantly and/or automatically detect borders. Embodiments of the invention provide an imaging system that automatically detects a border at a location within a vessel in response only to navigational input moving the image to that location. In some embodiments, systems and methods of the invention operate such that when a doctor moves an imaging catheter to a new location with in tissue, the system essentially instantly finds, and optionally displays, the border(s), calculates an occlusion, or both.

Abstract: A system that produces temperature estimations of a tissue surface comprises a base including a motion unit. A fiber assembly includes at least one fiber constructed and arranged to receive infrared energy from the tissue surface, the fiber assembly transmissive of infrared energy; the fiber assembly including a proximal end, a distal end and a body. An optical element redirects received infrared energy to the distal end of the fiber optic. A linkage is coupled between the base and the optical element, the fiber extending through the linkage, the linkage coupled to the motion unit at a proximal end and the optical element at a distal end, the motion unit constructed and arranged to rotate the linkage about the fiber assembly to thereby rotate the optical element at the distal end.

Abstract: Devices, systems, and methods for controlling an intravascular imaging device are provided. For example, in one embodiment a method includes communicating a control signal to an actuator of the intravascular imaging device to cause oscillation of an imaging element of the intravascular imaging device, wherein the intravascular imaging device further includes an acoustic marker; receiving imaging data from the imaging element of the intravascular imaging device; identifying the acoustic marker in the imaging data by determining a correlation between the imaging data and a template representative of the acoustic marker; adjusting an aspect of the control signal based on identifying the acoustic marker; and communicating the adjusted control signal to the actuator of the intravascular imaging device.

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: 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: 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.
