Patent number: 8503747Abstract: The present invention is an automated image analysis framework for cervical cancerous lesion detection. The present invention uses domain-specific diagnostic features in a probabilistic manner using conditional random fields. In addition, the present invention discloses a novel window-based performance assessment scheme for two-dimensional image analysis, which addresses the intrinsic problem of image misalignment. As a domain-specific anatomical feature, image regions corresponding to different tissue types are extracted from cervical images taken before and after the application of acetic acid during a clinical exam. The unique optical properties of each tissue type and the diagnostic relationships between neighboring regions are incorporated in the conditional random field model. The output provides information about both the tissue severity and the location of cancerous tissue in an image.Type: GrantFiled: May 3, 2011Date of Patent: August 6, 2013Assignee: STI Medical Systems, LLCInventors: Sun Young Park, Dustin Sargent, Ulf Peter Gustafsson

Publication number: 20120283574Abstract: The present invention is a diagnosis support system providing automated guidance to a user by automated retrieval of similar disease images and user feedback. High resolution standardized labeled and unlabeled, annotated and non-annotated images of diseased tissue in a database are clustered, preferably with expert feedback. An image retrieval application automatically computes image signatures for a query image and a representative image from each cluster, by segmenting the images into regions and extracting image features in the regions to produce feature vectors, and then comparing the feature vectors using a similarity measure. Preferably the features of the image signatures are extended beyond shape, color and texture of regions, by features specific to the disease. Optionally, the most discriminative features are used in creating the image signatures. A list of the most similar images is returned in response to a query. Keyword query is also supported.Type: ApplicationFiled: May 4, 2012Publication date: November 8, 2012Inventors: Sun Young Park, Dustin Michael Sargent, Rolf Holger Wolters, Ulf Peter Gustafsson

Patent number: 8289378Abstract: This invention uses LEDs and cross-polarization to produce bright, high-resolution digital images, both with and without glint (which adversely affects the clarity of standard colposcopic images), as well as streaming video at lower resolution. The invention allows for deeper layers of the tissue to be more efficiently visualized at multiple magnifications, thereby enhancing the invention's diagnostic capabilities, and it includes a focusing subsystem and a computerized data management system to archive and annotate still image data.Type: GrantFiled: November 14, 2008Date of Patent: October 16, 2012Assignee: STI Medical Systems, LLCInventors: Marcelo Esteban Soto-Thompson, Andrew Beaumont Whitesell, Ulf Peter Gustafsson

Patent number: 8090177Abstract: The present invention discloses a method for the detection of atypical vessels in digital cervical imagery. A pre-processing stage is applied to enhance the contrast of blood vessel features compared to the surrounding tissue. Next, a segmentation stage is applied to identify regions of interest for atypical vessels using texture and gradient information. Finally, a post-processing stage (1) identifies other clinically relevant features in the cervical imager, and removes these features from the region of interest; and (2) uses color, size, and shape information to further refine the region of interest to eliminate false positives and determine a final region of interest. This automated method of atypical vessel detection is especially useful for diagnostic purposes such as cervical cancer detection.Type: GrantFiled: August 1, 2008Date of Patent: January 3, 2012Assignee: STI Medical Systems, LLCInventors: Sankar Venkataraman, Wenjing Li, Ulf Peter Gustafsson

Publication number: 20110301447Abstract: A process and device for detecting colon cancer by classifying and annotating clinical features in video data containing colonoscopic features by applying a probabilistic analysis to intra-frame and inter-frame relationships between colonoscopic features in spatially and temporally neighboring portions of video frames, and classifying and annotating as clinical features any of the colonoscopic features that satisfy the probabilistic analysis as clinical features. Preferably the probabilistic analysis is Hidden Markove Model analysis, and the process is carried out by a computer trained using semi supervised learning from labeled and unlabeled examples of clinical features in video containing colonoscopic features.Type: ApplicationFiled: June 7, 2011Publication date: December 8, 2011Inventors: Sun Young Park, Dustin Sargent, Ulf Peter Gustafsson, Wenjing Li, Rolf Wolters, Stephen D.

Patent number: 7791008Abstract: The present invention discloses methods and systems for improved focusing of imaging systems for the acquisition of high-quality focused tissue image data. A light emitter (L) aims a focusing light beam (FLB) towards an object of interest (O) so that the focusing light beam (FLB) is at an angle relative to the optical axis (OA) of the imager (I). If the object of interest (O) is out of focus, the focusing light spot (FLS) will appear above or below the focal point in the image (I). The pixel difference between the center of the focusing light spot (FLS) and the focal point indicates the range adjustment value. The range between the imager (I) and the object of interest (O) can then be adjusted according to the range adjustment value using a lookup table or calculations.Type: GrantFiled: July 31, 2008Date of Patent: September 7, 2010Inventors: John Taylor Hargrove, Ulf Peter Gustafsson
