Improving resolution of medical images with deep dense convolutional neural network

Abstract: Doctors always desire high-resolution medical images to have accurate diagnosis. Super-resolution (SR) is a technology that can improve the resolution of medical images. Convolutional neural network (CNN)-based SR methods have achieved desired performance in natural images. In this paper, we apply a deep dense SR (DDSR) convolutional neural networks model to two types of medical images, including Computerized Tomography (CT) images and Magnetic Resonance imaging (MRI) images. This network densely connects ever… Show more

“…Recently, deep learning (DL) has reached promising achievements in medical imaging tasks, 5 such as segmentation, 6 registration, 7 image synthesizing, 8 and super resolution (SR). 9,10 There have many researchers explored the feasibility of DL-based MR image SR. 9,11,12 These investigations have suggested superior performances of the DL-based SR method over the conventional interpolation-and optimization-based methods 3,13 in terms of image quality and computation efficiency.…”

“…There are two significant reasons for this. The first is that the structure of medical images is different from natural images 8 . Unlike natural images, medical images can be in many other image modalities, 9 as in MRI, a slice by slice analysis may be required to diagnose a tumor 10 .…”

“…For example, there may be hundreds of slices belonging to a patient 11 . In addition, diseased tissues and anomalies have different characteristics from objects in natural images 8 . Another reason is that it is difficult to obtain medical images due to the low number of pictures taken compared to natural pictures.…”
