A transoral ultrasound probe for imaging a temporomandibular joint and a method of imaging a temporomandibular joint using a transoral probe.

A smart screw according to an embodiment may comprise: a screw main body which penetrates an artificial joint including a shell disposed on a hip joint of an object and a liner disposed on the inner surface of the shell and is then inserted into the hip joint; a transducer including a coupling layer that senses a sound wave signal reflected from the liner, a piezo-electric layer formed to determine a frequency of the sound wave signal, and a sound absorbing layer for absorbing the sound wave signal; and a processing module for generating a sound wave signal toward the liner and receiving the sound wave signal sensed by the coupling layer, measuring the thickness of the liner on the basis of the received sound wave signal, and transferring data about the measured thickness of the liner to the outside.

A method for intraoperative planning and facilitating a revision arthroplasty procedure includes displaying a virtual model of a bone, capturing positions of a tracked probe as the tracked probe contacts points at a perimeter of a primary implant component coupled to the bone, generating a virtual representation of an interface between the primary implant component and the virtual model of the bone using the positions of the tracked probe, planning a bone resection using the virtual representation of the interface, and guiding execution of the bone resection.

During acquisition of an ultrasound image feed, ultrasound control data frames are acquired that may be interspersed amongst the ultrasound data frames. The control data frames may use consistent reference scan parameters, irrespective of the scanner settings, and may not need to be converted to image frames. The control data frames can be passed to an artificial intelligence model, which predicts the suitable settings for scanning the anatomy that is being scanned. The artificial intelligence model can be trained with a dataset containing different classes of ultrasound control data frames for different settings, where substantially all the ultrasound control data frames in the dataset are consistently acquired using the reference scan parameters.

A method for measuring dynamic movement of a joint, the method comprising the steps of: measuring relative rotation of the joint using pair of Inertia measurement units, each attached to the skin on either side of said joint; capturing a plurality ultrasound images of a bone proximate to a first of said IMU's; identifying markers on said bone; tracking displacement of the markers; correlating said displacement with the relative rotation of the joint, and so; measuring the dynamic movement of the joint.

A computer-implemented method and system for selecting one or more regions of interest (ROIs) in an image. The method comprises: identifying one or more objects of interest that have been segmented from the image; identifying predefined landmarks of the objects; determining reference morphometrics pertaining to the objects by performing morphometrics on the objects by reference to the landmarks; selecting one or more ROIs from the objects according to the reference morphometrics, comprises identifying the location of the ROIs relative to the reference morphometrics; and outputting the selected one or more ROIs.

Devices, systems and/or methods for monitoring and/or stimulating osteogenesis use sensor data from a target site of a bone to produce a quantitative output that can be used to determine the healing rate of the patient, when the bone at the target has fully consolidated and/or to direct further treatment of the patient.

Described herein is an implantable device comprising a radiation-sensitive element (such as a transistor) configured to modulate a current as a function of radiation exposure to the transistor; and an ultrasonic device comprising an ultrasonic transducer configured to emit an ultrasonic backscatter that encodes the radiation exposure to the transistor. Further described herein is an implantable device comprising a radiation-sensitive element (such as a diode) configured to generate an electrical signal upon encountering radiation; an integrated circuit configured to receive the electrical signal and modulate a current based on the received electrical signal; and an ultrasonic transducer configured to emit an ultrasonic backscatter based on the modulated current encoding information relating to the encountered radiation.
