Publication number: 20140039299Abstract: Embodiments of a method, a tracking system, an MRI system, and a non-transitory computer readable medium that stores instructions for simultaneous imaging and tracking are presented. A designated signal and one or more characteristics corresponding to a plurality of imaging gradient waveforms are received. Further, a tracking pulse sequence is synchronized with an imaging pulse sequence at a determined point based on the designated signal. The tracking pulse sequence is then applied simultaneously with the imaging pulse sequence for acquiring corresponding response signals from an interventional device that includes at least one tracking coil and a tracking source configured to generate response signals at a tracking resonant frequency different from an imaging resonant frequency. A location of the tracking coil within or outside body of a subject is determined based on the response signals received from the tracking source and the characteristics corresponding to the imaging gradient waveforms.Type: ApplicationFiled: July 31, 2012Publication date: February 6, 2014Applicant: GENERAL ELECTRIC COMPANYInventors: Thomas Kwok-Fah Foo, Robert David Darrow, Florian Wiesinger

Publication number: 20140031668Abstract: A motion-sensing mechanism is provided that facilitates numerous aspects of the medical industry. In one aspect, the motion-sensing mechanism is used to track instruments and personnel in a field of view relative to a patient such that the instrument or personnel may be displayed on a heads-up display showing a model of the patient's anatomy. In another aspect, the motion-sensing mechanism makes a reference image of a patient, visitor, or staff such that when the subject of the reference images passes another (or the same) motion-sensing mechanism, the identity of the subject is determined or recognized. In still other aspects, the motion-sensing mechanism monitors motion of a portion of a patient's anatomy and compares the same to an expected motion for diagnostic evaluation of pain generators, physical therapy effectiveness, and the like.Type: ApplicationFiled: September 6, 2011Publication date: January 30, 2014Applicant: DISRUPTIVE NAVIGATIONAL TECHNOLOGIES, LLCInventors: Jean-Pierre Mobasser, Eric Potts, Dean Karahalios

Publication number: 20140005524Abstract: A fiducial marker system (210a-c) comprises a first unit and a second unit. The first unit is patient affixable and comprises a partly spherical inner surface having a first center point that is adapted to receive a touch probe measurement head for measuring the spatial position of the center point. The second unit is releasably attachable to an outer surface of the first unit, and has a second center point, wherein the first center point and the second center point are substantially identical when the second unit is attached to the first unit. For stereotactic therapy, a patient is imaged with the first and second unit assembled. Then the second unit is detached. A stereotactic frame (300) is attached to the first units via arms. Thus frameless imaging is provided in a frame based stereotactic surgery system with high precision. Repeated assembly of the frame (300) to the first units, remaining in the patient, provides advantageous fractionized stereotactic radiotherapy.Type: ApplicationFiled: July 3, 2013Publication date: January 2, 2014Applicant: Karolinska Institutet Innovations ABInventors: Elfar Ulfarsson, Anders Nordell, Bo Nordell

Publication number: 20130317347Abstract: A traceable surgical tool is positioned, monitored and displayed in real-time directly with pre-scanned three dimensional CT/MRI slices of a patient. The tool positioning and inclination is obtained by real time combined ultrasound (US)/RF transmissions between at least four transmitting units (TUs) and a mobile unit (MU) attached to or included in the tool. No more than three of the TUs may be coplanar. In some embodiments, at least one TU includes two US transmitters transmitting at different frequencies. Image space coordinates of the CT/MRI scanned patient are mapped by a one-to- one transformation onto real space coordinates of the patient undergoing a surgical procedure. The mapping is aided by, in the real space environment, touching once each of at least three markers fixedly attached to the patient and pre-scanned with the patient in the image space.Type: ApplicationFiled: March 5, 2013Publication date: November 28, 2013Inventor: Doron Kwiat
