Patent number: 10092188Abstract: The invention provides methods and compositions for determining whether a subject containing a stent immobilized in a blood vessel has asymptomatic stent thrombosis or is at risk of developing clinically symptomatic stent thrombosis. In one approach, the method involves imaging a region of the blood vessel that contains the stent using a probe that contains a fluorochrome, for example, a near-infrared fluorochrome, and a targeting moiety that binds a molecular marker indicative of the presence of asymptomatic stent thrombosis or the development of symptomatic stent thrombosis. To the extent that the subject displays one or more such markers, the probe binds to the markers and increases the local concentration of the probe in the vicinity of the stent. The imaging method identifies those patients that display a higher density of such markers in the vicinity of the stent. As a result, those patients can be monitored for, and/or treated to prevent, symptomatic stent thrombosis.Type: GrantFiled: September 30, 2014Date of Patent: October 9, 2018Assignee: VisEn Medical, Inc.Inventors: Farouc Jaffer, Milind Rajopadhye

Patent number: 10064584Abstract: The invention relates to a combined x-ray and optical (light-based) tomographic imaging system that provides functional information at greater resolution than can be achieved by optical tomography alone. The system is configured with one or more x-ray sources, x-ray detectors, light sources, and light detectors arranged on a gantry which rotates about an imaging chamber containing the object to be imaged. The system thereby allows both x-ray radiation and light to be directed into the object at multiple locations. Processing methods of the invention go beyond simple co-registration of images obtained from two or more imaging techniques. Both x-ray data and light data are used together in optical tomographic reconstruction to create the tomographic image, thereby allowing a more accurate and/or higher resolution final image.Type: GrantFiled: December 21, 2006Date of Patent: September 4, 2018Assignee: VisEn Medical, Inc.Inventor: Wael I. Yared

Patent number: 9901254Abstract: The invention relates to systems and methods for tomographic imaging of a subject comprising diffuse media by converting measurements of electromagnetic radiation, e.g., fluorescent light, obtained in free space exterior to the subject into data that would be measured if the subject were surrounded by an infinite and homogeneous diffusive medium, e.g., a medium with optical properties equal to the average optical properties of the subject. After applying a transformation to convert measurements to virtually-matched values, propagation of light is simulated from the index-matched surface to a set of virtual detectors exterior to the subject and arranged in a geometrically advantageous fashion, for example, in a planar array, thereby facilitating the use of fast reconstruction techniques.Type: GrantFiled: March 13, 2013Date of Patent: February 27, 2018Assignee: VisEn Medical, Inc.Inventors: Jorge Ripoll Lorenzo, Wael I.
