Figure 2.

Flowchart depicting the process of medical image analysis. Multiple acquired images undergo resampling and denoising, followed by contouring and binarization. Skeletonization is then applied, resulting in a skeletonized image, which is green-colored and overlain on the original image.

Preprocessing pipeline for magnetic resonance image analysis. Initially, the acquired images were resampled and denoised. Next, contouring and binarization were performed, followed by skeletonization to reduce contours to a single-pixel width. The processed contours were colorized in green and overlaid onto the denoised images to enhance thoracic contours. This automated preprocessing pipeline facilitated the analysis of thoracic expansion through dynamic imaging.
