    Abstract: Systems and methods for image registration includes an image feature detection module (116) configured to identify internal landmarks of a first image (110). An image registration and transformation module (118) is configured to compute a registration transformation, using a processor, to register a second image (112) with the first image based on surface landmarks to result in a registered image. A landmark identification module (120) is configured to overlay the internal landmarks onto the second image using the registration transformation, encompass each of the overlaid landmarks within a virtual object to identify corresponding landmark pairs in the registered image, and register the second image with the first image using the registered image with the identified landmarks.

    Abstract: The invention relates to a calibration apparatus for calibrating a system for introducing an influencing element like a radiation source into an object, particularly for calibrating a brachytherapy system. First and second images show a longish introduction device (12) like a catheter and a tracking device (16) like an electromagnetically trackable guidewire inserted into the introduction device as far as possible, and the introduction device and a calibration element (46) having the same dimensions as the influencing element and being inserted into the introduction device as far as possible. A spatial relation between the tracking device and the calibration element is determined based on the images for calibrating the system. Knowing this spatial relation allows accurately determining an influencing plan like a brachytherapy treatment plan and accurately positioning the influencing element in accordance with the influencing plan, which in turn allows for a more accurate influencing of the object.

    Abstract: A system (200) and method (900): access (910) a 3D reference image of a region of interest (ROI) (10) in a subject which was obtained using a first 3D imaging modality; segment (920) the ROI in the 3D reference image to define (930) a reference 3D coordinate system; acquire (940) 2D acoustic images of the ROI without absolute spatial tracking; generate (950) a standardized predicted pose for the 2D acoustic images with respect to a standardized 3D coordinate system (400) which was defined for a plurality of previously-obtained 3D images of corresponding ROIs in a plurality of other subjects which were obtained using the first 3D imaging modality; convert (960) the standardized predicted poses for the 2D acoustic images from the standardized 3D coordinate system to reference predicted poses in the reference 3D coordinate system; and use (970) the reference predicted poses for the 2D acoustic images to register the 2D acoustic images to the 3D reference image.

    Abstract: Ultrasound image devices, systems, and methods are provided. An ultrasound imaging system comprising a processor circuit in communication with an ultrasound probe comprising a transducer array, wherein the processor circuit is configured to receive, from the ultrasound probe, a first image of a patients anatomy; detect, from the first image, a first anatomical landmark at a first location along a scanning trajectory of the patients anatomy; determine, based on the first anatomical landmark, a steering configuration for steering the ultrasound probe towards a second anatomical landmark at a second location along the scanning trajectory; and output, to a display in communication with the processor circuit, an instruction based on the steering configuration to steer the ultrasound probe towards the second anatomical landmark at the second location.

    Abstract: Systems and methods for ultrasound image acquisition, tracking and review are disclosed. The systems can include an ultrasound probe coupled with at least one tracking device configured to determine a position of the probe based on a combination of ultrasound image data and probe orientation data. The image data can be used to determine a physical reference point and superior-inferior probe coordinates within a patient being imaged, which can be supplemented with the probe orientation data to determine lateral coordinates of the probe. A graphical user interface can display imaging zones corresponding to a scan protocol, along with an imaging status of each zone based at least in part on the probe position. Ultrasound images acquired by the systems can be tagged with spatial indicators and severity indicators, after which the images can be stored for later retrieval and expert review.

    Abstract: The present disclosure describes ultrasound systems and methods configured to determine the elasticity of a target tissue. Systems can include an ultrasound transducer configured to acquire echoes responsive to ultrasound pulses transmitted toward the tissue, which may include a region of increased stiffness. Systems can also include a beamformer configured to control the transducer to transmit a push pulse into the tissue, thereby generating a shear wave in the region of increased stiffness. The beamformer can be configured to control the transducer to emit tracking pulses adjacent to the push pulse. Systems can further include a processor configured to determine a displacement amplitude of the shear wave and based on the amplitude, generate a qualitative tissue elasticity map of the tissue. The processor can combine the qualitative map with a quantitative map of the same tissue, and based on the combination, determine a boundary of the region of increased stiffness.
