New imaging technique captures human heart with 'unprecedented detail'

Researchers with University College London and the European Synchrotron Radiation Facility (ESRF) have used a new X-ray technique, hierarchical phase-contrast tomography (HiP-CT), to capture images of the human heart in unprecedented detail. The group shared its images, as well as a full analysis, in Radiology.[1]

Images of the heart create using a new X-ray technique, hierarchical phase-contrast tomography (HiP-CT). The technology enables CT imaging of the heart and the ability to zoom in to the cellular level with unprecedented detail. Images courtesy of RSNA.

The new images were captured at the European Synchrotron Radiation Facility using hierarchical phase-contrast tomography. One specialist called them "Google Earth for the human heart." 

Self-cleaning TAVR valve offers potential of fewer clots, better outcomes

StreamlineValve self-cleaning TAVR valve inspired by nature. In a regular valve, abnormal flow and stagnation zones are prone to thrombosis (left). In the flow-controlled valve, taking an idea from bird's wings, a small volume of the blood flow is redirected to reduce stagnation zones as well as modulate the flow profile to be less turbulent and overall reducing flow-related thrombosis (right) Image/captions courtesy of European Heart Journal.

Inspired by nature and funded by the European Research Council, a group of scientists and engineers thinks its new research could represent a significant breakthrough in TAVR care.
