Publication number: 20160278678Abstract: An imaging system, such as a surgical microscope, laparoscope, or endoscope or integrated with these devices, includes an illuminator providing patterned white light and/or fluorescent stimulus light. The system receives and images light hyperspectrally, in embodiments using a hyperspectral imaging array, and/or using narrowband tunable filters for passing filtered received light to an imager. Embodiments may construct a 3-D surface model from stereo images, and will estimate optical properties of the target using images taken in patterned light or using other approximations obtained from white light exposures. Hyperspectral images taken under stimulus light are displayed as fluorescent images, and corrected for optical properties of tissue to provide quantitative maps of fluorophore concentration. Spectral information from hyperspectral images is processed to provide depth of fluorophore below the tissue surface. Quantitative images of fluorescence at depth are also prepared.Type: ApplicationFiled: February 15, 2016Publication date: September 29, 2016Inventors: Pablo Valdes, Frederic Leblone, Keith D.

Patent number: 9336592Abstract: A system and method for determining intraoperative locations of a lesion in tissue from lesion locations determined in preoperative imaging includes determining three dimensional locations of surface features of the organ in the preoperative images. A preoperative surface map is extracted from stereo images annotated with surface features from preoperative images. An intraoperative surface map of the organ is extracted from stereo images, and surface features are identified in the stereo images corresponding to surface features annotated into the preoperative surface map. Three dimensional displacements of the surface features are determined and used to constrain a computer model of deformation of the organ. In embodiments, the model of deformation is adapted or constrained to model locations and dimensions of surgical cavities using an optical flow method and/or locations of surgical instruments in the organ. The model of deformation is used to determine intraoperative locations for the lesion.Type: GrantFiled: February 1, 2013Date of Patent: May 10, 2016Assignee: THE TRUSTEES OF DARTMOUTH COLLEGEInventors: Xiaoyao Fan, David W.

Publication number: 20150374308Abstract: A method of generating corrected fluorescence data of concentrations of a targeted fluorophore in tissue of a subject includes administering first and second fluorescent contrast agents to the subject, the first contrast agent targeted to tissue of interest, the second agent untargeted. The tissue is illuminated with light of a first stimulus wavelength and first data is acquired at an appropriate emissions wavelength; the tissue is illuminated at a second stimulus wavelength and second data is acquired at a second emissions wavelength associated with the second agent, the first and second emissions wavelength differ. Difference data is generated by subtracting the second data from the first data. A system provides for stimulus and capture at multiple wavelengths, with image storage memory and subtraction code, to perform the method. Corrected data may form an fluorescence image, or is used to generate fluorescence tomographic images.Type: ApplicationFiled: February 13, 2014Publication date: December 31, 2015Applicant: The Trustees of Dartmouth CollegeInventors: Kenneth Tichauer, Robert W.
