20140099011 | REMOVAL OF A-SCAN STREAKING ARTIFACT - This invention generally relates to the removal of streaking artifacts and periodic noise from tomographic images. The method comprises obtaining an A-scan from an imaging data set. The A-scan having a signal and the signal defining an amplitude. Noise specific to the A-scan is estimated. The amplitude of the A-scan is scaled based on its specific estimated noise floor. In another aspect, a plurality of A-scans is obtained from an imaging data set. Each of the plurality of A-scans has a signal and the signal defines an amplitude. Noise specific to each A-scan of the plurality of A-scans is estimated. Each A-scan of the plurality of A-scans is scaled by the A-scan's specific estimated noise floor. | 04-10-2014 |
20140099012 | SYSTEMS FOR CORRECTING DISTORTIONS IN A MEDICAL IMAGE AND METHODS OF USE THEREOF - The invention relates generally systems for correcting distortion in a medical image and methods of use thereof. Methods and systems for displaying a medical image of a lumen of a biological structure, generally comprise obtaining image data of a lumen of a biological structure from an imaging device, correcting the image data for translational distortions, in which correcting is accomplished without reference to another data set, and displaying a corrected image. | 04-10-2014 |
20140100439 | GUIDEWIRE ARTIFACT REMOVAL IN IMAGES - 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. | 04-10-2014 |
20140100440 | SYSTEM AND METHOD FOR INSTANT AND AUTOMATIC BORDER DETECTION - 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. | 04-10-2014 |

20140100449 | AUTOMATIC STENT DETECTION - 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. | 04-10-2014 |
20140193057 | METHODS AND SYSTEMS FOR TRANSFORMING LUMINAL IMAGES - 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. | 07-10-2014 |
