Method for identifying human joint characteristics
A method for identifying human joint characteristics, the method including the steps of: using a mobile imaging device, taking at least one image of the joint, and then identifying a joint pain location by identifying three different locations in the image near the joint, so that a center point between the locations can be triangulated.
METHOD FOR MEASURING RELAXATION TIME OF ULTRASHORT ECHO TIME MAGNETIC RESONANCE FINGERPRINTING
The present disclosure discloses a method for measuring relaxation time of ultrashort echo time magnetic resonance fingerprinting. In the method, semi-pulse excitation and semi-projection readout are adopted to shorten echo time (TE) to achieve acquisition of an ultrashort T2 time signal; and image acquisition and reconstruction are based on magnetic resonance fingerprint imaging technology. A TE change mode of sinusoidal fluctuation is introduced, so that distinguishing capability of a magnetic resonance fingerprint signal to short T2 and ultrashort T2 tissues is improved, and multi-parameter quantitative imaging of the short T2 and ultrashort T2 tissues and long T2 tissues is realized. Non-uniformity of a magnetic field is modulated into phase information of the fingerprint signal through the TE of the sinusoidal fluctuation; a B0 graph is directly reconstructed according to an amplitude-modulated signal demodulation principle; and the phase change caused by a BO field is compensated in the fingerprint signal.
Method and system for performing multi-bone segmentation in imaging data
A computer implemented method for performing bone segmentation in imaging data of a section of a body structure is provided. The method includes: Obtaining the imaging data including a plurality of 2D images of the section of the body structure; and performing a multiphase local-based hybrid level set segmentation on at least a subset of the plurality of 2D images by minimizing an energy functional including a local-based edge term and a local-based region term computed locally inside a local neighborhood centered at each pixel of each one of the 2D images on which the multiphase local-based hybrid level set segmentation is performed, the local neighborhood being defined by a Gaussian kernel whose size is determined by a scale parameter (σ).
Method and system for correlating anatomy using an electronic mobile device transparent display screen
Method and system form a correlated view of human or other animal anatomy using at least one transparent display screen associated with an electronic mobile device. The view relates an optical view with other electromagnetic spectrum images with a non-optical electromagnetic image of selected portions of human or other animal anatomy. At least three visible position markers associate with selected positions of a predetermined portion of human or other animal anatomy. The disclosure forms a correlated view of the predetermined portion of human or other animal anatomy by relating said at least one non-optical electromagnetic image of the at least three visible position markers with a visual image of said at least three visible position markers. The view correlates the size and dimensions of the optical view and non-optical electromagnetic image of the predetermined portion of human or other animal anatomy.
3D UTE IMAGING USING VARIABLE-TE STACK-OF-SPIRALS ACQUISITION
Some aspects of the present disclosure relate to ultrashort-echo-time (UTE) imaging. In one embodiment, a method includes acquiring UTE imaging data associated with an area of interest of a subject. The acquiring comprises applying an imaging pulse sequence with a three-dimensional (3D) spiral acquisition and a nonselective excitation pulse. The method also includes reconstructing at least one image of the area of interest from the acquired UTE imaging data.
Orthopaedic implant with sensors
A monitoring system includes: (1) an implant having at least one sensor and configured for at least partial insertion into a patient, a first one of sensors being in contact with a perimeter of a hole in a body portion of the implant for accepting a fastener; (2) a microchip associated with the implant and the sensor, the microchip configured to receive at least a first signal from the sensor; (3) a transmitter associated with the microchip for transmitting a second signal, representative of the first signal; (4) a receiver located outside of the patient, the receiver configured receive the transmitted second signal; and (5) a display device associated with the receiver, the display device configured to provide an audible or visual representation of the second signal to a user.
Device and method for normalizing implant strain readings to assess bone healing
A device and method for treating a bone includes a bone plate including first and second portions joined to one another via a connecting portion, a rigidity of the connecting portion being less than rigidities of each of the first and second portions in combination with a first sensor mounted on the first portion measuring strain on the first portion and a second sensor mounted on the second portion measuring strain on the second portion.
SURGICAL ORIENTATION SYSTEM AND METHOD
A system and method for detecting and measuring changes in angular position with respect to a reference plane is useful in surgical procedures for orienting various instruments, prosthesis, and implants with respect to anatomical landmarks. One embodiment of the device uses dual orientation devices of a type capable of measuring angular position changes from a reference position. One such device provides information as to changes in position of an anatomical landmark relative to a reference position. The second device provides information as to changes in position of a surgical instrument and/or prosthesis relative to the reference position.
Device and method for measuring vibration transmittance of sternum
A method for measuring vibration transmittance of a sternum noninvasively includes producing vibration, transmitting the vibration to a first side the sternum through skin and soft tissues, obtaining response data of the sternum from a second side of the sternum through skin and soft tissues, which first and second sides of the sternum are on different sides of the midline of the sternum, and processing said response data for determining transmittance of vibration of the sternum. The response data may be used for defining state of a patient such as sternal instability of the breastbone or abnormal healing in the sternum after open chest surgery by surgeons.
SYSTEMS AND METHODS FOR MEASURING AND ASSESSING SPINE INSTABILITY
Diagnostic systems and methods for measuring and assessing spine instability are described which involve reconstruction of a dynamic three-dimensional model of a patient's spine moving through a range of motions, and optimization of the three-dimensional model to provide relative three-dimensional position and orientation data for each vertebra in the spine throughout the motion. Vertebral movement is thereby accurately measured and instability determined for presentation in a user-friendly form.
