Demonstrating the virtual planning of the tumor segmentation, tumor wrapping with a safety margin, and guide designing. The image illustrates the importance of using advanced imaging techniques such as PET/CT to visualize the tumor and surrounding structures accurately. The red outline indicates the tumor segmentation, and a safety margin is added to ensure complete removal of the tumor (R0). The guide is designed based on these measurements to provide a precise outline for the surgeon during the resection procedure. This virtual planning can help improve the accuracy and effectiveness of the surgical procedure, resulting in better patient outcomes
