  • Patent number: 10357224
    Abstract: A medical ultrasound acquisition-data analysis device acquires channel data (144) via ultrasound received on the channels, uses the acquired channel data to estimate data coherence and derive dominance of an eigen-value of a channel covariance matrix and, based on the estimate and dominance, distinguishes microcalcifications (142) from background. Microcalcifications may then be made distinguishable visually on screen via highlighting, coloring, annotation, etc. The channel data operable upon by the estimating may have been subject to beamforming delays and may be summed in a beamforming procedure executed in the estimating. In the estimating and deriving, both field point-by-field point, multiple serial transmits (116, 118) may be used for each field point. In one embodiment results of the estimating and deriving are multiplied point-by-point and submitted to thresholding.

  • Patent number: 10279194
    Abstract: The invention relates to a HDR brachytherapy system comprising an ultrasound sensor for being arranged at the location of a brachytherapy catheter (12), wherein the ultrasound sensor is adapted to generate an ultrasound signal based on ultrasound radiation, which has been sent by an ultrasound imaging device preferentially comprising a TRUS probe (40) and which has been received by the ultrasound sensor. The position of the ultrasound sensor is determined based on the generated ultrasound signal, and based on this position of the ultrasound sensor the pose and shape of the brachytherapy catheter and/or the position of a HDR radiation source are determined. This allows for a very accurate determination of the pose and shape of the brachytherapy catheter and/or of the position of the HDR radiation source, which in turn can lead to an improved HDR brachytherapy.

  • Publication number: 20190029651
    Abstract: An ultrasonic diagnostic imaging system and method filter the data of successive ultrasonic images of moving tissue. At least two successive images are clutter filtered to remove clutter in the image data from stationary objects. The successive images and the filtered successive images are both used to produce displacement images of frame to frame tissue motion, and a quality metric is produced of the quality of the estimated displacement. The displacement image with the best quality metric is selected for further processing such as the production of strain images. The selected displacement image may further be spatially filtered to reduce boundary artifacts.

  • Patent number: 10034658
    Abstract: A medical imaging probe (102) for contact with an imaging subject includes an indicium placement apparatus for, while the probe is in contact, selectively performing an instance of marking the subject so as to record a position of the probe. The device may further include a feedback module for determining whether an orientation, with respect to a the mark, that currently exists for a medical imaging probe of the device meets a criterion of proximity to a predetermined orientation. Responsive to the determination that the criterion is met, a quantitative evaluation may be made automatically and without need for user intervention, via live imaging via the probe, of a lesion that was, prior to the determination, specifically identified for the evaluation. Change, such as growth (116), in the lesion, like a brain lesion, may thereby be tracked over consistent sequential imaging acquisitions, such as through ultrasound.

  • Publication number: 20180000446
    Abstract: A target biopsy system employing an ultrasound probe (20), a target biopsy needle (30) and a ultrasound guide controller (44). In operation, the ultrasound probe (20) projects an ultrasound plane intersecting an anatomical region (e.g. a liver). The target biopsy needle (30) include two or more ultrasound receivers (31) for sensing the ultrasound plane as the target biopsy needle (30) is inserted into the anatomical region. In response to the ultrasound receiver(s) (31) sensing the ultrasound plane, the ultrasound guide controller (44) predicts a biopsy trajectory of the target biopsy needle (30) within the anatomical region relative to the ultrasound plane. The prediction indicates the biopsy trajectory is either within the ultrasound plane (i.e., an in-plane biopsy trajectory) or outside of the ultrasound plane (i.e., an out-of-plane biopsy trajectory).
