Special Issue Information

Dear Colleagues,

With the booming growth of advanced technologies (ATs), especially the recent advancements in artificial intelligence, pattern recognition, and machine vision, utilizing AT-based methods for medical image analysis has become an active research area, both in the medical industry and academia.

This Special Issue (SI) will show the recent progress of AT research in medical image analysis and clinical applications. It will also discuss the existing problems in the field and provide possible solutions and future directions. More specifically, it will highlight state-of-the-art clinical applications that include four major human body systems: the nervous system, the cardiovascular system, the digestive system, and the skeletal system. Overall, according to the best available evidence, deep learning models perform well in medical image analysis; however, algorithms derived from small-scale medical datasets that impede clinical applicability cannot be ignored. Future directions could include federated learning, benchmark dataset collection, and utilizing domain subject knowledge as priors. In conclusion, recent advanced deep learning technologies have achieved great success in medical image analysis due to their high accuracy, efficiency, stability, and scalability. Technological advancements that can alleviate the high demands on high-quality, large-scale datasets could be a future development in this area.

In order to better preserve the anatomical structure information of Computed Tomography (CT) source images and highlight the metabolic information of lesion regions in Positron Emission Tomography (PET) source images, a hybrid multimodal medical image fusion method (LatLRR-GAN) based on Latent low-rank representation (LatLRR) and the dual discriminators Generative Adversarial Network (ED-D2GAN) is proposed. Firstly, considering the denoising capability of LatLRR, source images were decomposed by LatLRR. Secondly, the ED-D2GAN model was put forward as the low-rank region fusion method, which can fully extract the information contained by the low-rank region images. Among them, encoder and decoder networks were used in the generator; convolutional neural networks were also used in dual discriminators. Thirdly, a threshold adaptive weighting algorithm based on the region energy ratio is proposed as the salient region fusion rule, which can improve the overall sharpness of the fused image. The experimental results show that compared with the best methods of the other six methods, this paper is effective in multiple objective evaluation metrics, including the average gradient, edge intensity, information entropy, spatial frequency and standard deviation. The results of the two experiments are improved by 35.03%, 42.42%, 4.66%, 8.59% and 11.49% on average. Full article
