Simultaneous MR and Ultrasound Imaging

Magnetic Resonance Imaging (MRI) has excellent soft-tissue contrast, multi-planar imaging capability, and sensitivity to subtle changes in tissue morphology and function Ultrasound imaging, on the other hand, has high temporal resolution volumetric imaging capabilities, the ability to quantify of blood flow, and detect boundaries with small acoustic impedance differences. In addition ultrasound...

Incremental 3D Ultrasound Imaging from a 2D scanner

W e have been developing an interactive system that wil! display 3D structures from a series o f two-dimensional 2D images acquired incrementally by a conventional 2D ultrasound echographic (2DE) scanner. T h e user-guided scanner head is mounted on a mechanical arm that tracks the position and orientation of an image frame. W e expect in the coming year t o complete a version of the system in ...

Research interface on a programmable ultrasound scanner.

MOTIVATION Commercial ultrasound machines in the past did not provide the ultrasound researchers access to raw ultrasound data. Lack of this ability has impeded evaluation and clinical testing of novel ultrasound algorithms and applications. OBJECTIVES Recently, we developed a flexible ultrasound back-end where all the processing for the conventional ultrasound modes, such as B, M, color flow...

Ultrasound Spatial Compound Scanner for Improved Visualization in Vascular Imaging

A new off-line multi-angle ultrasound compound scanner has been built with the aim of improving visualization of vascular tissue. Images are recorded from 3 to 11 insonification angles over a range of 40 to 50 degrees and the individual images are combined (averaged) into a single image (spatial compounding). Compared to conventional B-mode imaging, this multi-angle compound imaging (MACI) meth...

Acquire real-time RF digital ultrasound data from a commercial scanner

Although new ultrasound signal processing can be designed from simulation data or recorded data, the development and prototyping of new medical ultrasound imaging tools is essentially based on processing the radio frequency (RF) data, which is the signal generated by the ultrasound probe. Unfortunately, the diversity and technological level of knowledge required for implementing a whole ultraso...
