Patent number: 11903761Abstract: The present disclosure describes ultrasound imaging systems and methods that may be used to image, for example, breast tissue. An ultrasound imaging system according to one embodiment may include a probe, a sensor attached to the probe and operatively associated with a position tracking system, a processor configured to receive probe position data from the position tracking system. The user interface may be configured to provide instructions for placement of the probe at a plurality of anatomical landmarks of a selected breast of the subject and receive user input to record the spatial location of the probe at each of the plurality of anatomical landmarks. The processor may be configured to determine a scan area based on the spatial location of the probe at each of the plurality of anatomical landmarks and generate a scan pattern for the selected breast. The processor may be further configured to monitor movement of the probe.Type: GrantFiled: July 13, 2022Date of Patent: February 20, 2024Assignee: KONINKLIJKE PHILIPS N.V.Inventors: James Robertson Jago, Julia Dmitrieva, Gary Cheng-How Ng, Thomas Shu Yin Tang

Patent number: 11903770Abstract: The present invention relates to a medical imaging apparatus. The apparatus comprises an ultrasound acquisition unit including an ultrasound probe for acquiring ultrasound image data of a patient. An image data interface is provided for receiving 3D medical image data of the patient and a position determining unit for determining a position of the ultrasound probe. A calibration unit determines a transfer function between the ultrasound image data and the 3D medical image data at a plurality of positions (C) of the ultrasound probe and provides a corresponding plurality of calibrated transfer functions and calibration positions. A computation unit synchronizes the ultrasound image data and the 3D medical image data on the basis of a position of the ultrasound probe and the plurality of calibrated transfer functions, said computation unit is further adapted to weight the calibrated transfer functions on the basis of a position of the ultrasound probe.Type: GrantFiled: October 2, 2020Date of Patent: February 20, 2024Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Cecile Dufour, Benoit Jean-Dominique Bertrand Maurice Mory, Thomas Shu Yin Tang

Patent number: 11672505Abstract: A fusion imaging system co-registers and fuses real time ultrasound images with reference images such as those produced by MRI or CT imaging. In an illustrated implementation, previously acquired CT or MRI or ultrasound images are loaded into the system. An ultrasound system is operated in conjunction with a tracking system so that the ultrasound probe and images can be spatially tracked. A computerized image processor registers the probe position with a reference image of the anatomy being scanned by the probe and determines whether the probe appears to be inside the skin line of the subject. If that is the case it is due to probe compression of the subject, and the reference image is modified to locate the skin line in the reference image in front of the ultrasound probe. The modified reference images can then be readily co-registered and fused with the ultrasound images produced by the probe.Type: GrantFiled: April 21, 2022Date of Patent: June 13, 2023Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Cecile Dufour, Roberto Jose Ardon, Gary Cheng-How Ng, Thomas Shu Yin Tang

Patent number: 11540811Abstract: The present disclosure describes ultrasound imaging systems and methods, which may enable the automatic identification of an image plane in a pre-operative volume corresponding to a real-time image of a moving region of interest. An example method includes receiving real-time ultrasound image data from a probe associated with a position-tracking sensor, generating real-time images based on the real-time ultrasound data and deriving a motion model from the real-time ultrasound image data. The method may further include automatically identifying an image plane in a pre-operative data set to correspond to the real-time ultrasound image by correcting for motion-induced misalignment between the real-time data and the pre-operative data.Type: GrantFiled: January 4, 2019Date of Patent: January 3, 2023Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Cecile Dufour, Thomas Shu Yin Tang, Gary Cheng-How Ng

Patent number: 5991838Abstract: A docking station structure is used to operatively connect a notebook computer to desktop computer peripheral devices. The docking station has an internal receiving chamber into which the portable computer may be manually inserted, an electrical connector positioned within the receiving chamber, a travel plate movably carried within the receiving chamber, a motorized drive system operative to drive the travel plate toward and away from the electrical connector, and a latch structure carried by the travel plate for movement therewith. With the travel plate in a wait position thereof, the portable computer is rearwardly inserted into the receiving chamber. In response to such insertion, the latch structure automatically locks the computer to the travel plate, and the drive system rearwardly moves the travel plate to mate the electrical connector with a corresponding connector on the computer, thereby operatively linking the computer to the peripheral devices.Type: GrantFiled: February 17, 1994Date of Patent: November 23, 1999Assignee: Dell USA, L.P.Inventors: Dan E.
