Publication number: 20220375574Abstract: Described are techniques for determining an accurate ground-truth Bayesian Inter-Reviewer Agreement Rate (BIRAR) from unreliable sources. For instance, a process can include obtaining an initial set of diagnostic imaging exams, wherein each diagnostic imaging exam includes a severity grade associated with an initial radiologist. For each diagnostic imaging exam, two or more secondary quality assurance (QA) reviews can be obtained for each diagnostic imaging exam, wherein the secondary QA reviews are associated with QA'ing radiologists different than the initial radiologist. One or more inter-reviewer agreement rates can be determined for the QA'ing radiologists, based on the secondary QA reviews associated with the QA'ing radiologists.Type: ApplicationFiled: May 4, 2022Publication date: November 24, 2022Inventors: Tarmo Aijo, Daniel Elgort, Xiaojin Dong, Denis Whelan, Richard Herzog, Murray Becker, Robert Epstein, Irwin Keller, Ron Vianu

Publication number: 20120150019Abstract: A magnetic resonance system includes a main magnet (12,12?, 12?) which generates a static magnetic field B0 in an examination region (14,14?,14?). A hyperpolarization device (26,26?,26?) directly hyperpolarizes nuclear spins via electromagnetic radiation endowed with orbital angular momentum transverse to the static magnetic field B0 for inducing magnetic resonance. The hyperpolarization device includes an orientation tracking unit (100) which determines an orientation of the endowed photon beam relative to a predefined external coordinate system. An orientation modifier (104) adjusts the orientation of the endowed photon beam to an optimal orientation according to the determined relative orientation.Type: ApplicationFiled: July 9, 2010Publication date: June 14, 2012Applicant: KONINKLIJKE PHILIPS ELECTRONICS N.V.Inventors: Daniel Elgort, Remus Albu

Publication number: 20120126810Abstract: In a pH measurement system, a magnet defines a BO magnetic field with which selected dipoles preferentially align in an examination region. A orbital angular momentum system endows electromagnetic (EM) radiation with orbital angular momentum (OAM) and transmits the OAM endowed EM radiation to the examination region to at least one of (1) enhance the preferential alignment of the selected dipoles with the BO magnetic field and (2) excite the aligned dipoles to resonate. A receive coil receives resonance signals from the resonating dipoles. An analysis or measurement unit determines a pH in the examination region by analyzing the resonance signals.Type: ApplicationFiled: July 9, 2010Publication date: May 24, 2012Applicant: KONINKLIJKE PHILIPS ELECTRONICS N.V.Inventors: Daniel Elgort, Remus Albu

Patent number: 7894877Abstract: A system for automatically adapting image acquisition parameters based on imaging and/or device tracking feedback is provided. An example system includes a subsystem for acquiring images (e.g., MR) of an object and tracking data for a device (e.g. catheter) inserted into the object and controllably moveable within the object. The system also includes an image processor for processing the images and a device tracking logic for computing device parameters (e.g., speed, direction of travel, rate of speed change, position, position relative to a landmark, device orientation). Based on the images and device parameter computations, a parameter control and adjustment logic can automatically update one or more image acquisition parameters that control the image acquisition subsystem.Type: GrantFiled: May 14, 2003Date of Patent: February 22, 2011Assignee: Case Western Reserve UniversityInventors: Jonathan S.

Patent number: 7620440Abstract: An improved imaging technique and apparatus for direct temporal encoding of spatial information of an object is presented. The signal collected from the object after application of excitation energy in a magnetic field is directly representative of the spatial position of the object without the need for the signal to undergo mathematical transformation. This is a result of the excitation scheme that generates transverse magnetization across the field of view that is a function of X (read-out) and Z (slice select) positions, resulting in a two-dimensional phase profile that, upon application of a constant gradient along the Z axis, elicits a signal that is directly attributable to the spatial position along the read-out dimension without application of mathematical transformation.Type: GrantFiled: May 16, 2003Date of Patent: November 17, 2009Assignee: Case Western Reserve UniversityInventors: Daniel Elgort, Brian M.

Patent number: 7596402Abstract: A probe suitable for attachment to, or incorporation in, a medical interventional device, such as a catheter, and which may be employed for tracking, imaging, or both, includes a first material having an MR resonance frequency distinct from a resonance frequency of a second material adjacent to the first material. The probe may include one or more coils, or it may be wireless, that is, it may have no coils.

Publication number: 20050054913Abstract: A method of automatically adjusting at least one MR image parameter for an interventional procedure includes adaptively tracking an MR micro-coil catheter and automatically updating an imaging scan plane's position and orientation, as well as other features including, but not limited to, field-of-view, resolution, temporal resolution, slice thickness, tip angle, and TE. The disclosed system provides a more natural interface for a physician operating the MR scanner during an interventional procedure. The scanner can react to changes in the clinical environment and automatically adjust a number of image parameters. For example, during catheter insertion, images are acquired at lower resolutions, and possibly larger fields of view, to help facilitate faster updates and tracking. Once the catheter reaches a target area in the tissue and its motion slows, an MR image of higher resolution, and possibly lower field of view, is acquired.Type: ApplicationFiled: May 5, 2004Publication date: March 10, 2005Inventors: Jeffrey Duerk, Daniel Elgort, Chris Flask, Claudia Hillenbrand, Jonathan Lewin, Frank Wacker, Eddy Wong
