Movement Tracking and False Positive Reduction Method for Microwave Colonoscopy Systems
Artikel i vetenskaplig tidskrift, 2024

This paper presents a novel computational method for addressing the challenge of uncontrolled antenna movement in microwave imaging systems for colonoscopy. The proposed method tracks the movement of the antenna array by analyzing phase shifts in S-parameters across multiple channels. By exploiting the symmetry of the probe and correlating phase changes with displacement, this technique reduces false positives due to probe movements artifacts in real-time. Simulated and experimental results in a colon phantom model show that this method can correct displacements of up to 6 mm, reducing the artifacts in reconstructed images notably.
