Methods for developing a machine learning model of a neural network for classifying medical images.

The present invention proposes an apparatus and method for characterizing a tissue in a first region of a subject. The apparatus comprises a receiving unit (210) for receiving ultrasound data of the tissue in the first region and ultrasound data of a predetermined target reference tissue of said subject; a deriving unit (220) for deriving a subject-specific model of the target reference tissue on the basis of the ultrasound data of the target reference tissue; and a characterizing unit (230) for determining a match between tissue in the first region and the target reference tissue on the basis of the subject-specific model and ultrasound data of the tissue in the first region. Unlike conventional tissue characterization based on a large cohort of patient data, the proposed subject-specific model is personalized for the specific subject without any generalization, resulting in higher sensitivity and/or accuracy. Preferably, the subject-specific model of the target reference tissue is derived on the basis of both the ultrasound data of the target reference tissue and the ultrasound data of a background reference tissue of a different type than the target reference tissue.

An ultrasound imaging apparatus (200, 600) may include at least one controller (210, 610) which may be configured to: acquire ultrasound data of an anatomical region-of-interest (ROI), the ultrasound data including at least two frames acquired at different times over an interval of time as a push force is applied to induce movement in the anatomical ROI; determine a correlation between at least two of the acquired frames and form corresponding correlation coefficients; generate a correlation coefficient (CC) map based upon the determined correlation information between the at least two frames; and distinguish fluid from tissue within the CC map based upon a comparison of the correlation coefficients with at least one threshold value.

A method of generating a 3D ultrasound image includes acquiring a 3D volumetric data set corresponding to a 3D imaging volume of an ultrasound probe in a 3D detection volume; acquiring a position of the ultrasound probe with respect to the 3D detection volume; acquiring a position of an interventional medical device with respect to the 3D detection volume; determining a position of the interventional medical device relative to the 3D imaging volume of the ultrasound probe; determining an interventional medical device-aligned plane that intersects with a longitudinal axis of the interventional medical device; extracting a texture slice from the 3D imaging volume for a corresponding interventional medical device-aligned plane positional and rotational orientation; mapping the texture slice onto the interventional medical device-aligned plane; and rendering the interventional medical device-aligned plane as a 3D ultrasound image and displaying the rendered 3D ultrasound image on a display screen.

An ultrasound image diagnostic apparatus includes, a transmitter to repeat alternating supply of first pulse signals and second pulse signals to the ultrasound probe, the second pulse signals being generated by polarity inversion of the first pulse signals; a receiver; a memory to store first sound ray data corresponding to the first pulse signals; an adder to add the stored first sound ray data and second sound ray data corresponding to the second pulse signals; a line-signal processor to generate fundamental line data and harmonic line data; a needle emphasizing signal processor to generate needle image data from the generated fundamental image data; a harmonic signal processor to generate harmonic image data; a synthesizer to combine the needle image data and the harmonic image data; and a display controller to display the synthesized image data.

Aspects described herein disclose devices, systems, and methods for use in contexts such as minimally invasive surgery (MIS). A device is provided herein having a proximal portion and a distal portion, and an ultrasound transducer may be disposed within the distal portion and configured to scan tissue and identify certain portions of a patent's anatomy during the scanning process. The results of the detection may be presented to an operator of the device aurally and/or visually, such as in a 3-D volumetric image. By scanning the tissue, identifying the anatomy, and presenting the results to an operator, unnecessary damage to elements of the patients anatomy may be avoided or lessened. In some aspects, multiple transducers may be positioned on the device to increase the scanning range and/or scanning accuracy of the device. The device may provide an inner channel for the passage of surgical tools while scanning tissue.

The present invention is directed to a system and method for performing tissue, preferably bone tissue manipulation. The system and method may include implanting markers on opposite sides of a bone, fractured bone or tissue to facilitate bone or tissue manipulation, preferably in-situ closed fracture reduction. The markers are preferably configured to be detected by one or more devices, such as, for example, a detection device so that the detection device can determine the relative relationship of the markers. The markers may also be capable of transmitting and receiving signals. An image may be captured of the bone or tissue and the attached markers. From the captured image, the orientation of each marker relative to the bone fragment may be determined. Next, the captured image may be manipulated in a virtual or simulated environment until a desired restored orientation has been achieved. The orientation of the markers in the desired restored orientation may then be determined. The desired relationship between markers may then be programmed into, for example, the detection device. Next, actual physical reduction and/or manipulation of the bone may begin. During the manipulation procedure, the orientation of the markers may be continuously monitored and when the markers substantially align with the virtual or simulated orientation of the markers in the desired restored orientation, an indicator signal is transmitted.
