    Abstract: A computer-implemented method for active control of ultrasound image acquisition includes accessing image data representing a series of ultrasound images acquired over a period of time from an ultrasound probe and identifying an object of interest in at least one of the images. The method further includes detecting changes in a position of the ultrasound probe and/or an orientation of the ultrasound probe over the period of time with respect to the object of interest, or changes in a position of the object of interest and/or an orientation of the object of interest over the period of time with respect to the ultrasound probe. The method further includes adjusting at least one ultrasound image acquisition parameter based on the detected changes in the position and/or the orientation of the ultrasound probe and/or based on the detected changes in the position and/or the orientation of the object of interest.

    Abstract: Methods and systems using magnetic resonance and ultrasound for tracking anatomical targets for radiation therapy guidance are provided. One system includes a patient transport configured to move a patient between and into a magnetic resonance (MR) system and a radiation therapy (RT) system. An ultrasound transducer is also provided that is hands-free and electronically steerable, securely attached to the patient, such that the ultrasound transducer is configured to acquire four-dimensional (4D) ultrasound images concurrently with one of an MR acquisition or an RT radiation therapy session. The system also includes a controller having a processor configured to use the 4D ultrasound images and MR images from the MR system to control at least one of a photon beam spatial distribution or intensity modulation generated by the RT system. The system determines the previously-acquired correct MR images that represent a specific motion state at some time, t, by a plurality of transformations that allow the representation of the position of fiducial markers in the corresponding ultrasound images to match that of a prior ultrasound acquisition.

    Abstract: In one embodiment, a method of detecting centerline of a vessel is provided. The method comprises steps of acquiring a 3D image volume, initializing a centerline, initializing a Kalman filter, predicting a next center point using the Kalman filter, checking validity of the prediction made using the Kalman filter, performing template matching, updating the Kalman filter based on the template matching and repeating the steps of predicting, checking, performing, and updating for a predetermined number of times. Methods of automatic vessel segmentation and temporal tracking of the segmented vessel is further described with reference to the method of detecting centerline.
