Abstract: Described herein are example methods, devices and systems for motion compensation in ultrasonic respiration monitoring. A respiration detection system includes a first probe placed on a front side of a patient's body and a second probe placed on a dorsal side of the body. The first probe includes an ultrasound transducer, a first accelerometer unit and a magnetic field sensor unit, and the second probe includes a second accelerometer unit and magnetic field sensor unit. Due to respiration of the patient, the abdominal region of the body moves, creating measurement errors when an ultrasound beam is directed towards an internal structure (internal tissue region) inside the patient's body. Correction for such measurement errors uses input data from the first and second accelerometer units and the magnetic field sensor unit.

Abstract: A method of visualizing spinal nerves includes receiving a 3D image volume depicting a spinal cord and a plurality of spinal nerves. For each spinal nerve, a 2D spinal nerve image is generated by defining a surface within the 3D volume comprising the spinal nerve. The surface is curved such that it passes through the spinal cord while encompassing the spinal nerve. Then, the 2D spinal nerve images are generated based on voxels on the surface included in the 3D volume. A visualization of the 2D spinal images is presented in a graphical user interface that allows each 2D spinal image to be viewed simultaneously.

Abstract: An overlay of anatomy is created for a fluoroscopy image. Anatomy detected in angiographic images is used to locate anatomy in the fluoroscopy image. For each cardiac phase, the anatomy is detected multiple times from different cardiac cycles using angiographic images. The fluoroscopic overlay for each cardiac phase is formed from a combination of angiographic candidates fit from the different cardiac cycles to the fluoroscopic image. To further enhance the combination, prediction of the anatomy position from one phase to the next phase is used.

The method involves tracking a feature of interest within the sequence of the second volumetric data sets, determining time varying spatial orientation of a plane containing the feature of interest in the sequence of the first volumetric image data sets by transferring the plane from the second volumetric image data sets to the first volumetric image data sets, reformatting the three-directional velocity information into one-directional velocity information on the plane, and performing bi-dimensional quantitative flow analysis using the one-directional velocity information. A corresponding apparatus and computer program are also disclosed and claimed.

Abstract: Two detector units and two holding arms are provided. The detector units are each disposed on a part of an arc of a circle surrounding a subject. The holding arms each disposed on the arc hold the detector units individually. The holding arms move independently along the circle surrounding the subject, thereby causing the detector units to move. Consequently, a first detector unit is held with a first holding arm entirely, and a second detector unit is held with a second holding arm entirely. This causes less swing of the detector units achieving a simple configuration.

Abstract: Ultrasound radiation using a single tone burst pulse is applied to a selected location in a tissue region. The induced shear wave is detected in the region and its spectral distribution is calculated and analyzed. This detection may be repeated with other excitation pulses having different widths or different shapes at the same location. The spectral analysis of the detected shear wave is performed according to a nonlinear shear model for solving nonlinearity and viscoelasticity of the tissue at a single location. The detection location can be at one point at a time for imaging two-dimensional or three-dimensional tissue nonlinearities and shear wave properties including nonlinear magnitude variations, nonlinear phase variations, nonlinear coefficients, and viscoelasticity.
