Low‐Dose Computed Tomography Image Denoising Vision Transformer Model Optimization Using Space State Method

International Journal of Imaging Systems and Technology, Volume 35, Issue 6, November 2025.
ABSTRACT Low‐dose computed tomography (LDCT) is widely used to promote reduction of patient radiation exposure, but the associated increase in image noise poses challenges for diagnostic accuracy. In this study, we propose a Vision Transformer (ViT)‐based denoising framework enhanced with a State Space Optimizing Block (SSOB) to improve both image ...

Optimizing Skin Cancer Classification With ResNet‐18: A Scalable Approach With 3D Total Body Photography (3D‐TBP)

International Journal of Imaging Systems and Technology, Volume 35, Issue 6, November 2025.
ABSTRACT Skin cancer, particularly melanoma, remains a major public health challenge because of its rising incidence and mortality rates. Traditional methods of diagnosis, like dermoscopy and biopsies, are invasive, time‐consuming, and highly dependent on clinical experience.
