A transducer transmits into the bone a first plurality of excitation pulses at a plurality of frequencies and measures a plurality of echoes corresponding to the plurality of excitation pulses. An ultrasound machine calculates a plurality of energies each corresponding to a respective one of the plurality of echoes and identifies a lowest echo corresponding to a lowest of the plurality of energies. The ultrasound machine matches the lowest echo to a corresponding one of the first plurality of excitation pulses, the corresponding one of the first plurality of excitation pulses having a chosen frequency. The ultrasound machine generates an acoustic impulse response by deconvolving the corresponding one of the first plurality of excitation pulses with the lowest echo, and generates an updated sensing matrix by convolving the initial sensing matrix with the acoustic impulse response. Subsequent ultrasounds use the updated sensing matrix.

A system and related methods for performing nerve detection during surgical access using ultrasound testing during surgery.

An ultrasonic diagnosis apparatus includes a position detector, and control circuitry. The position detector detects a position in a three-dimensional space of one of an ultrasonic image and an ultrasonic probe. The control circuitry uses a vivisection view defined in a three-dimensional space. The control circuitry associates a structure related to a subject included in the ultrasonic image with a structure included in the vivisection view using a position and orientation in a first three-dimensional coordinate system of the structure related to the subject included in the ultrasonic image and a position and orientation in a second three-dimensional coordinate system of the structure included in the vivisection view.

An ultrasonic treatment instrument for use in arthroscopic surgery, includes a probe having a main body that is configured to transmit ultrasonic vibration, and a treatment portion that is provided on a distal side of the main body and is configured to cut a hard tissue and/or a soft tis e by transmission of the ultrasonic vibration; and a sheath unit that includes an inner sheath covering an outer peripheral surface of the main body in the probe, and an outer sheath covering an outer peripheral surface of the inner sheath and forming a suction path between the outer peripheral surface of the inner sheath and the outer sheath, wherein a distal end of the inner sheath extends to a position closer to the treatment portion of the probe than a distal end of the outer sheath.

The present disclosure is directed to a method of surgery, such as knee replacement surgery and hip replacement surgery that achieves optimal implant sizing and placement within a surgically repaired joint.

An implantable position detecting system is configured to detect a position of an implantable device with respect to a body structure. The system includes at least one proximity measuring transducer configured to be implanted on the body structure a distance from the implantable device, the at least one proximity measuring transducer being configured to receive energy from an external electromagnetic field generated by an external sensing interface, wherein the at least one proximity sensor is configured to emit an emitted signal responsive to the electromagnetic energy and to receive distance information comprising a sensing signal that is responsive to the distance from the implantable device.

A system and method for the use of the results from a structural analysis of a patient's bone from a clinical scan, to be used clinically to manage patients in a widespread and consistent fashion.

An extra-oral dental imaging apparatus can obtain a radiographic image of a portion of a head of a patient. Exemplary dental apparatus and/or method embodiments can position a subject for dental radiographic imaging by providing a bitable dental arch mounting apparatus to offset the antero-posterior plane of the dental imaging apparatus and the plane of symmetry of the dental arch mounting apparatus. In one embodiment, the offset can be provided by a tilted dental arch mounting apparatus (e.g., relative to the horizontal).

Disclosed herein are acoustic transmission systems comprising an acoustic wave generator configured to generate an acoustic wave and propagate the acoustic wave through a tissue of a specimen, and a non-Hermitian complementary metamaterial (NHCMM) configured to add a first amount of energy amplification coherently to the acoustic wave to account for energy loss in the acoustic wave as a result of the wave propagating through the tissue of the specimen. The acoustic wave generator can be an ultrasound generator, and the tissue can be a cranium.
