JERUSALEM, Oct. 7 (Xinhua) -- Israeli and U.S. researchers have developed an innovative technology that safely and efficiently steers curved surgical needles inside the body while avoiding damage to tissues, the northern Israel Institute of Technology (Technion) said on Thursday.

Technion researchers and their colleagues from the University of North Carolina (UNC) have developed an algorithm that steers surgical needles along 3D curvilinear trajectories.

The new development is intended for numerous medical procedures, such as biopsies and localized therapy delivery for cancer, where the target tissue is hidden behind a bone or vulnerable tissue.

In such cases, surgeons have the difficult task to avoid anatomical vulnerable obstacles, especially when using straight needles.

Based on relevant medical images, such as a computed tomography (CT) or magnetic resonance imaging (MRI) scan, the new algorithm computes the optimal trajectory that will lead the needle to the target while avoiding damage.

The new algorithm also informs the user when there is no possible motion plan to reach the specific target.

According to the researchers, the new technology is expected to lead to additional applications based on automated steerable needles. Enditem
