Patent number: 11660064Abstract: A controller (310) for identifying positioning of an intravascular ultrasound probe (952) includes a memory (362) that stores instructions (884) and a processor (361) that executes the instructions (884). When executed by the processor (361), the instructions (884) cause the controller (310) to execute a process that includes receiving first signals from at least one element of the intravascular ultrasound probe (952). The process also includes receiving second signals from an external ultrasound probe. Based on the first signals and the second signals, the controller (310) determines a position of the intravascular ultrasound probe (952) in a tracking space that includes the intravascular ultrasound probe (952) and the external ultrasound probe.Type: GrantFiled: June 17, 2019Date of Patent: May 30, 2023Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Ramon Quido Erkamp, Francois Guy Gerard Marie Vignon, Shyam Bharat, Kunal Vaidya, Ameet Kumar Jain

Patent number: 11653893Abstract: An interventional instrument (30) having ultrasound sensors (S1, S2, S3, S4, . . . ) is tracked using an ultrasound imaging device (10) that acquires and displays a 2D ultrasound image of a visualization plane (18), and performs 2D ultrasound sweeps for a range of plane angles (?) obtained by rotating the ultrasound probe (12) and encompassing the visualization plane angle. For each ultrasound sensor, an optimal plane is found based on its emitted signal strength over the range of plane angles, and the ultrasound sensor is located in its optimal plane by analyzing the sensor signal as a function of the timing of the beams fired by the ultrasound probe. These locations in their respective optimal planes are transformed to a 3D reference space using a transform (42) parameterized by plane angle, and a visual indicator is displayed of spatial information (T, L) for the interventional instrument generated from the locations of the one or more ultrasound sensors in the 3D reference space.Type: GrantFiled: April 27, 2017Date of Patent: May 23, 2023Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Shyam Bharat, Ameet Kumar Jain, Antonio Bonillas Vaca

Publication number: 20230066948Abstract: A method and system is for assisting a user in positioning an ultrasound probe relative to a subject's body. In use, the user moves the probe through a series of positions, and ultrasound image data is captured for each position, the data at each position corresponding to a particular imaging view of the anatomical region being imaged. An assessment procedure (16) is operable to process ultrasound data for different imaging views, and to determine for the data for each view a rating, representative of the suitability of the data for that view for observing one or more anatomical features or deriving one or more clinical parameters from the data. Guidance feedback is generated (18) for the user for assisting the user in positioning the probe, wherein the guidance feedback is based on a history (26) of image view quality over time over the course of the imaging procedure.Type: ApplicationFiled: January 25, 2021Publication date: March 2, 2023Inventors: Shyam Bharat, Alvin Chen, Grzegorz Andrzej Toporek, Balasundar Iyyavu Raju, Jonathan Thomas Sutton
