Abstract: A method for assessing blood vessel stenosis using image data of a subject is disclosed. The image data represents a vascular structure of the subject. The method comprises: (a) segmenting, from the image data, a vessel segment representing a segment of a blood vessel, (b) obtaining, using the image data, a plurality of two-dimensional images of the vessel segment; said plurality of two-dimensional images representing respective cross-sections of the vessel segment, (c) identifying, for each of the plurality of two-dimensional images, a lumen area comprising lumen pixels representing a lumen of the corresponding cross-section, (d) obtaining a quantitative measure using the lumen areas of successive cross-sections of the vessel segment, and (e) assessing blood vessel stenosis using the quantitative measure. A computer system for performing the above method is disclosed.

Abstract: The present disclosure generally relates to an automated method and system for generating a panoramic visualization of a coronary arterial tree of a subject. The method comprises: acquiring an image volume of a thoracic cavity of the subject, the image volume providing a three-dimensional (3D) representation of the thoracic cavity; isolating a coronary structure in the 3D representation by abating one or more other anatomical structures in the thoracic cavity; abating one or more portions of the coronary structure in the 3D representation that attenuate visualization of the coronary arterial tree; generating, by maximum intensity projection (MIP), a plurality of MIP images of the coronary structure from the 3D representation; and compositing the MIP images to generate the panoramic visualization of the coronary arterial tree.

Abstract: There is provided a method for multi-modal imaging of tissue. The method includes: providing a fiber probe over a target area of the tissue, the fiber probe including a plurality of source fiber channels, a plurality of detector fiber channels and a plurality of fiducial marker channels, the plurality of source fiber channels, the plurality of detector fiber channels and the plurality of fiducial marker channels having a predetermined spatial arrangement in the fiber probe; directing light through each of the plurality of source fiber channels of the fiber probe to the target area in succession for performing optical imaging of the target area; obtaining optical imaging data of the target area based on attenuated light from the target area detected through the plurality of detector fiber channels due to said light directed to the target area; obtaining MRI data of the target area based on a MRI of the target area; and coregistering the optical imaging data and the MRI data based on a plurality of fiducial features captured in the MRI data corresponding to the plurality of fiducial marker channels of the fiber probe. There is also provide a corresponding system for multi-modal imaging of tissue.
