Videotomografiya: How to Shoot The Heartbeat

"Please lie still!" – These words constantly hear people using one of the most modern diagnostic techniques – magnetic resonance imaging (MRI). The fact is that with the help of MRI to obtain clear images of moving bodies is almost impossible.

“Please lie still!” – These words constantly hear people using one of the most modern diagnostic techniques – magnetic resonance imaging (MRI). The fact is that with the help of MRI to obtain clear images of moving bodies is almost impossible.

Rather, it was impossible to develop the German scientists from the Max Planck Institute of new technology that allows literally to “filming” of moving bodies, including the beating heart.

In 1980 the process of MRI takes a few minutes, is currently recording the image section of the body only takes a few seconds, thanks to technologies developed by German researchers FLASH (quick shot at a small angle) – 20 milliseconds. Actually it allows authorities to explore in real time with inaccessible until now temporal resolution and without artifacts. With the new MRI can be studied, for example, opening the jaw, to capture images of the speech organs or heartbeats.

According to scientists, the new method can improve the control of conditions such as coronary heart disease and heart failure.

Currently, the new technology “fast” MRI can be easily implemented in modern operating devices, but there is some problem connecting sufficiently powerful computers to reconstruct the image. For example, a minute of the heart, taken in a real-time, a total of 2-3 thousand Image 2 GB. Scientists have partially solved this problem by using the mathematical algorithm, which divides the process in parallel threads. All the complex calculations associated with the construction of the video, conducted with the use of fast graphics processors, which were originally developed for computer games and three-dimensional visualization.
