These images can assist in identifying changes under the retina's surface, such as edema. This study proposes a novel deep learning model AR U-Net++ for segmenting retinal layers and fluids. The four retinal layers ILM (Internal Limiting Membrane), IPL (Inner Plexiform

TACT: Text attention based CNN-Transformer network for polyp segmentation Int. J. Imaging Syst. Technol. (IF 3.3) Pub Date : 2023-11-17 Yiyang Zhao, Jinjiang Li, Zhen Hua
Colorectal cancer (CRC) has been one of the top three disease in the world in terms of incidence for many years. Therefore, how to prevent and treat CRC has become a topic of concern for an increasing number of people, and colonoscopy is the most effective detection method in polyp examination. According to studies, 90% of CRC is caused by adenomatous polyps of the large intestine. In clinical practice

Improved GAN for image resolution enhancement using ViT for breast cancer detection Int. J. Imaging Syst. Technol. (IF 3.3) Pub Date : 2023-11-17 Kamakshi Rautela, Dinesh Kumar, Vijay Kumar
Breast cancer has a significant mortality rate and is widespread among women. Detecting it early is crucial for effective treatment. While mammograms provide detailed anatomical visuals, their accuracy is hindered by low sensitivity and high background noise, especially in dense breast tissue. This study introduces a new network architecture integrating generative adversarial networks (GANs) and vision

Width measurement of retinal vessels using cubic spline fitting and extended edge-searching mode Int. J. Imaging Syst. Technol. (IF 3.3) Pub Date : 2023-11-17 Linyuan Huang, Feng Liu
Abnormal changes in the retinal vessel width usually indicate the presence of certain diseases. This paper presents a novel model to measure the width of retinal vessels. This method firstly employs cubic spline fitting to determine the vessel cross-sectional direction at the center point of a vessel profile, then uses the extended edge-searching mode to detect vessel edge points along the vessel cross-sectional
