Abstract: In many medical applications, it is crucial to match or register two different image data with each other, for example live image data with previously obtained 3D image data. The present disclosure relates to registration of a 3D image dataset with (live) ultrasound data. Rather than reconstructing an image from the ultrasound data and registering the reconstructed image with the 3D image dataset, the approach of the present disclosure matches the ultrasound A mode signals output by an ultrasound transducer with simulated ultrasound A mode signals generated from the 3D image dataset.

Abstract: A system and a computer-implemented method for identifying a region of interest for image registration is provided. The method includes analyzing three-dimensional CT or MRI image data of a tissue to identify one or more structural elements therein and determining a spatial arrangement of the structural elements, accessing first ultrasound image data of the tissue and performing a first image registration of the first ultrasound image data with the CT or MRI image data at a first accuracy, and identifying, based on the spatial arrangement of the structural elements, a region of interest for a subsequent second image registration of second ultrasound image data of the tissue with the CT or MRI image data at a second accuracy that is higher than the first accuracy.

Abstract: A bicycle mounted bulletproof armor shield system comprising a bicycle and two triangularly shaped body structures, the first structure is dimensioned to be contained within the area of the bicycle defined by the top tube, the down tube and the seat tube. The second structure is dimensioned to be contained within the area of the bicycle defined by the seat tube, the seat stay and the chain stay. Both structures are made of a bulletproof material. Handles are provided on the first body structure to facilitate positioning.

Abstract: A tractor-trailer landing gear mechanism for helping support a trailer end, includes a pair of elongated extendable and retractable telescoping legs. A reversible electrical motor interconnects the legs, for causing them to be retracted or extended to a desired predetermined latching position. The upright tubular member includes a plurality of outwardly extending bores, for receiving a plurality of corresponding latching pins. A plurality of similar normally deactivated solenoids are disposed on the outer sleeve to drive a safety pin into latching engagement with a corresponding bore, when the leg is extended to a desired length. A plurality of normally deactivated detectors are mounted on corresponding solenoids, for sensing the presence of a predetermined latching position. A control board includes a plurality of manually activated switches, for causing the motor to rotate in predetermined directions, and for causing the landing gear mechanism to either retract or extend.
