Imagine you have a blurry vacation photo, but you want to see every detail of that beautiful sunset. Well, researchers have come up with an amazing solution! In this study, scientists propose a new technique for improving the resolution of 3D medical images. They use a method called nonconvex nonlocal Tucker decomposition, which sounds fancy but simply means they break down the image into smaller parts and use patterns within these parts to enhance the resolution. It’s like assembling puzzle pieces to create a clearer picture! Unlike previous methods that use a different approach, these scientists apply a tensor folded-concave penalty to achieve the desired outcome. They also ensure the image maintains smoothness in different dimensions by using weighted 3D total variation. The experiments conducted prove that their method surpasses other state-of-the-art techniques when it comes to enhancing different types of medical images, including brain MRI and abdominal CT scans. If you’re intrigued by this breakthrough, I encourage you to dive into the full article and learn more!
Limited by hardware conditions, imaging devices, transmission efficiency, and other factors, high-resolution (HR) images cannot be obtained directly in clinical settings. It is expected to obtain HR images from low-resolution (LR) images for more detailed information. In this article, we propose a novel super-resolution model for single 3D medical images. In our model, nonlocal low-rank tensor Tucker decomposition is applied to exploit the nonlocal self-similarity prior knowledge of data. Different from the existing methods that use a convex optimization for tensor Tucker decomposition, we use a tensor folded-concave penalty to approximate a nonlocal low-rank tensor. Weighted 3D total variation (TV) is used to maintain the local smoothness across different dimensions. Extensive experiments show that our method outperforms some state-of-the-art (SOTA) methods on different kinds of medical images, including MRI data of the brain and prostate and CT data of the abdominal and dental.
