  • Communicating computer-aided detection results in a standards-based medical imaging environment
    Patent number: 6909795
    Abstract: A method, system, and method of doing business in a standards-based medical imaging environment is described in relation to the communication of computer-aided detection (CAD) results among devices, with one embodiment relating to the DICOM standard. CAD results are fixably integrated into the pixels of a secondary image derived from a source image, and the secondary image is transferred using a DICOM Secondary Capture Image Information Object Instance (SCI-IOI). The DICOM SCI-IOI is transferred to a viewing workstation, whereby a clinician can open, manipulate, and view the secondary image in a side-by-side comparison with the source image or derivative images thereof. Advantageously, CAD results are communicated to the clinician in a DICOM-conforming manner independent of whether the viewing workstation supports standard DICOM accommodations, such as CAD Structured Report Information Object Instances (CAD SR-IOIs), for the type of CAD results that need to be presented.

  • RADAR APPARATUS FOR IMAGING AND/OR SPECTROMETRIC ANALYSIS AND METHODS OF PERFORMING IMAGING AND/OR SPECTROMETRIC ANALYSIS OF A SUBSTANCE FOR DIMENSIONAL MEASUREMENT, IDENTIFICATION AND PRECISION RADAR MAPPING
    Patent number: 6864826
    Abstract: Radar apparatus and methods of use thereof for imaging and/or spectrometric analysis. The invention employs pulsed radar signals for magnifying, imaging, scale measuring, identifying and/or typecasting the composition of substances by radargrammetric imaging and/or statistical analysis of energy/frequency spectrums. The invention may be used to locate and/or distinguish a substance from other substances, to image a substance/feature and to monitor the movement of an imaged substance/feature. The systems and methods can be adapted for a variety of applications at a wide range of scales and distances, from large scale, long range applications such as geophysical imaging/analysis, to the small scale such as material typecasting applications and small scale (including microscopic) imaging/analysis, including biological and medical imaging and diagnostic applications. The invention includes novel antenna assemblies and novel data processing techniques.

  • Registration of 3-D imaging of 3-D objects
    Publication number: 20060072810
    Abstract: A three-dimensional-based modeling method and system designed for dentistry and related medical (and appropriate non-medical) applications. Data capture means produces a point cloud representing the three-dimensional surface of an object (e.g., dental arch). Three-dimensional recognition objects are provided, particularly within those areas in the image field that have low image definition, and particularly in such of these areas that appear in overlapping portions of at least two images, to provide the three-dimensional image processing software with position, angulation, and orientation information sufficient to enable highly accurate combining (or “stitching”) of adjoining and overlapping images. Alignment, and creation of aligned related objects or models thereof, such as maxillar and mandibular arches, is facilitated.
