Core Concepts
Circular Medical Image Super-Resolution (CMISR) proposes a closed-loop framework with explicit under-resolution and super-resolution units, achieving superior reconstruction performance in medical imaging.
Abstract
Introduction to Medical Imaging:
Medical imaging techniques are essential for disease diagnosis.
Advantages include low radiation and cost, while disadvantages include low quality and resolution.
Medical Image Super-Resolution (MISR):
Focuses on enhancing resolution of medical images.
General ISR algorithms can be adapted for MISR.
Traditional MISR Approaches:
Utilize open-loop architecture with under-resolution and super-resolution units.
Feedback mechanisms are crucial for performance enhancement.
Proposed CMISR Framework:
Circular MISR introduces a global feedback-based closed-cycle framework.
Combines model-based and learning-based approaches for improved performance.
Experimental Results:
CMISR outperforms traditional MISR in reconstruction performance.
Particularly effective for medical images with strong edges or intense contrast.
