MedSAM enables zero-shot prostate segmentation in micro-ultrasound

Researchers have developed a novel zero-shot pipeline using the MedSAM foundation model to segment prostate boundaries in high-frequency micro-ultrasound images. This method aims to improve early detection of prostate cancer by overcoming the limitations of conventional ultrasound and the challenges posed by acoustic speckle in micro-ultrasound. The pipeline integrates MedSAM with image enhancement techniques like CLAHE and Fourier smoothing, demonstrating a significant reduction in boundary-distance error and achieving segmentation overlap comparable to non-expert human raters.
