Publication number: 20240142516Abstract: A multispectral inspection (MSI) device for analyzing an electronic item having a printed circuit board (PCB). An electronic power supply powers the electronic item in accordance with one or more test vectors. An optical imaging scanner, terahertz (THz) imaging scanner, and a functional imaging scanner are each operative to scan the electronic item. An electronic processor is programmed to scan the various scanners and control the power supply to acquire optical, THz, and functional images of the electronic item. The images are combined to form a standard three-dimensional (3D) signature and artificial intelligence (AI) classifiers are applied to the 3D signature to perform non-destructive analyses of the electronic item.Type: ApplicationFiled: January 9, 2024Publication date: May 2, 2024Inventors: Thomas F. Kent, Jeremiah P. Schley, Anthony F. George, Richard J. Higgins, Katie T. Liszewski, David Maung

Patent number: 9072490Abstract: In one embodiment, an image processing apparatus includes a difference image generating unit and a display controlling unit. The difference image generating unit generates a difference image by calculating a difference in a second X-ray transmission image from a first X-ray transmission image, the second X-ray transmission image being an image in which a myocardial tissue of an examined subject is not opacified and the first X-ray transmission image being an image in which the myocardial tissue of the examined subject is opacified with a contrast agent that has been injected into a coronary artery. The display controlling unit exercises control so that a predetermined display unit displays the difference image that has been generated by the difference image generating unit.Type: GrantFiled: December 20, 2010Date of Patent: July 7, 2015Assignees: Toshiba Medical Systems Corporation, The Johns Hopkins UniversityInventors: Takuya Sakaguchi, Hisato Takemoto, Joao A.

Patent number: 8965085Abstract: An image processing apparatus according to the present embodiment includes a correcting unit. The correcting unit identifies, based on an observation value of a residual contrast material component that is injected to a subject before a predetermined timing and remains in the subject, the residual contrast material component and a new contrast material component that is newly injected to the subject after the predetermined timing regarding a contrast material component that is included in an image, and corrects an observation value of the contrast material component included in the image.Type: GrantFiled: May 3, 2013Date of Patent: February 24, 2015Assignees: Toshiba Medical Systems Corporation, Fujita Health University, The Johns Hopkins UniversityInventors: Takuya Sakaguchi, Takashi Ichihara, Jingwu Yao, Richard T.

Publication number: 20140086461Abstract: A predetermined time-based index ratio such as time-based fractional flow reserve (FFR) is determined for evaluating a level of blood circulation between at least two locations such as a proximal location and a distal location in a selected blood vessel in the region of interest. One time-based FFR is obtained by normalizing a risk artery ratio by a reference artery ratio.Type: ApplicationFiled: September 25, 2012Publication date: March 27, 2014Applicants: THE JOHNS HOPKINS UNIVERSITY, TOSHIBA MEDICAL SYSTEMS CORPORATIONInventors: Jingwu YAO, Takuya SAKAGUCHI, Jeff TROST, Richard T.

Patent number: 8615116Abstract: A computed tomography system has a support stage constructed and arranged to support a subject while under observation, an x-ray illumination system arranged proximate the support stage to illuminate the subject with x-rays, an x-ray detection system arranged proximate the support stage to detect x-rays after they pass through the subject and to provide signals based on the detected x-rays, and a data processing system in communication with the x-ray detection system to receive the signals from the x-ray detection system. The computed tomography system has a dynamic mode of operation and a scanning mode of operation. The data processing system extracts information concerning a dynamic process of the subject based on signals from both the dynamic mode and the scanning mode of operation.Type: GrantFiled: September 29, 2008Date of Patent: December 24, 2013Assignees: The Johns Hopkins University, Toshiba Medical Systems CorporationInventors: Albert Clark Lardo, Richard T.

Patent number: 8160338Abstract: An apparatus includes a transformation table acquiring unit, a blood-flow information acquisition unit and a blood-flow image generating unit. The transformation table acquiring unit obtains a transformation table for transforming unspecified information representing a concentration of a contrast medium in a myocardium into an unspecified blood flow value image based on a CT image acquired in a concentration transition period. The blood-flow information acquisition unit obtains information representing the concentration of the contrast medium based on a CT image acquired during a constant concentration period. The blood-flow image generating unit generates a blood flow value image based on the information representing the concentration of the contrast medium according to the transformation table.Type: GrantFiled: May 20, 2008Date of Patent: April 17, 2012Assignees: Toshiba Medical Systems Corporation, The Johns Hopkins UniversityInventors: Takashi Ichihara, Richard T.

Patent number: 7853309Abstract: An X-ray CT apparatus comprises a blood-flow information acquisition unit, a correction value calculating unit and a blood-flow image generating unit. The blood-flow information acquisition unit obtains information of a relative blood flow rate in the myocardium of the subject based on the CT image. The correction value calculating unit obtains a correction value based on the CT image in a concentration transition period defined to be a period from immediately after start of a continuous injection of a contrast medium into the subject until the contrast medium reaching the myocardium increases and is be in a state where it can be considered that the contrast medium is saturated at a constant value. The blood-flow image generating unit generates a blood flow value image in the myocardium by correcting the information of the relative blood flow rate with the correction value.Type: GrantFiled: March 10, 2005Date of Patent: December 14, 2010Assignees: Toshiba Medical Systems Corporation, The Johns Hopkins UniversityInventors: Takashi Ichihara, Toshihiro Rifu, Joao A.
