  • Combined B-mode / tissue doppler approach for improved cardiac motion estimation in echocardiographic images
    Patent number: 9629615
    Abstract: A method for cardiac motion estimation includes: receiving a set of echocardiographic images of a heart, the echocardiographic images including B-mode ultrasonic images and Tissue Doppler Imaging (TDI) images; and calculating, by the image processing machine, a motion field representing the motion of the heart using the B-mode ultrasonic images and applying a velocity constraint from the TDI images. A system for cardiac motion estimation, includes: an imaging device configured to acquire a set of echocardiographic images of a heart, the echocardiographic images including B-mode ultrasonic images and TDI images; a data storage device in communication with the imaging device and configured to store the set of echocardiographic images; an image processing machine in communication with the data storage device and configured to calculate a motion field representing the motion of the heart using the B-mode ultrasonic images and applying a velocity constraint from the TDI images.

  • Multimodal cardiac phantom for imaging
    Patent number: 9386960
    Abstract: A multimodal cardiac phantom has a body structure with a shape and properties that mimic the elasticity, ultrasound, and magnetic properties of cardiac tissue. The multimodal cardiac phantom is advantageously produced from a polymer such as polyvinyl alcohol. The polyvinyl alcohol may include magnetic resonance imaging (MRI) markers and ultrasound markers. The multimodal cardiac phantom can be used to evaluate and to configure apparatuses for imagining cardiac tissue.
