Abstract: The present disclosure describes systems and methods for determining if a feature of interest is present in a volume or plane scanned by an imaging system. In examples, one or more imaging planes are analyzed for anatomical landmarks to determine whether a feature of interest is present. If the feature of interest is present, scan parameters may be determined to scan an adjusted volume that includes the feature of interest. In some applications, the adjusted volume may allow the imaging system to increase a volume rate.

Abstract: An ultrasound system has user selectable tissue specific presets by which a user can condition the ultrasound system to be optimized for specific types of diagnostic exams. After an exam type has been selected and the exam commenced, a user manipulates imaging and workflow controls to better visualize the target anatomy. The user has the choice of setting up the system so that imaging and workflow settings are maintained when the tissue specific presets are changed, or to reset the imaging and workflow settings to default values upon a change of the tissue specific presets.

Abstract: In some aspects, techniques and systems for improving a well survey are described. An error analysis is performed to identify errors associated with operating a well survey instrument in a magnetic environment at a wellbore location. Based on the error analysis, an instrument performance model (IPM) is selected for a well survey by the well survey instrument. In some cases, the IPM is selected such that the errors satisfy specifications of the IPM.

Abstract: This invention relates to surveying wellbores. In particular this invention provides methods of correcting magnetic surveys for the effects introduced by magnetic mud. The method of the present invention comprises, in broad terms, measuring gravitational and magnetic fields at least one position in the wellbore; comparing the measured fields with theoretical values, and introducing scale factors to adapt the measured values to equal the theoretical values thus making it possible to cope with the effects of magnetic mud.

Abstract: A method is disclosed for correcting for the distorting effect of cross-axial magnetic interference on the readings of a well survey tool using a reduced number of measurements and measuring locations. A well survey tool connected to a drill string assembly measures the gravitational and distorted terrestrial magnetic fields at two or more axially displaced locations in an axially extending well bore. The measurements are made from two or more different orientations (tool faces) of the tool about the well axis. Initial values for the tool inclination, azimuth and tool face angle are first determined without correction for the cross-axial magnetic interference introduced by the drill string assembly and the survey tool. Measurements made at each location and tool face are referred to the toots coordinate system and variations introduced by the different tool face angles are used to estimate the cross-axial interference. The estimated interference is used to improve the estimate of the azimuth.
