            <h1 class="section-title">Abstract</h1>
            <ul class="news-list">
                Radiotherapy is a critical cancer treatment that uses external beam radiation to kill cancer cells.
                Effective treatment planning, which determines radiation dose distribution for tumor volumes, is
                essential to maximize
                the likelihood of a cure while minimizing toxicity. Gross Tumor Volume (GTV) and Clinical Target
                Volume (CTV) are two
                key targets in radiotherapy planning. GTV is the visible tumor extent on Computed Tomography (CT)
                scans, while CTV
                encompasses GTV and describes the extent of microscopic, unimageable tumor spread. Accurate
                delineation of GTV and CTV
                is essential in radiotherapy planning, however, manual slice-by-slice annotation on CT scans is
                time-consuming and
                labor-intensive for radiation oncologists. Automating this process can significantly reduce planning
                time and enhance
                radiotherapy efficiency. <br>
                Based on the success of SegRap2023, SegRap2025 aims to address ongoing challenges in GTV
                segmentation and firstly focus
                on the Lymph Node (LN) CTV segmentation. It provides two datasets collected from diverse cohorts:
                one with data from 260
                NPC patients annotated for GTV, and another with 402 patients annotated for LN CTV. It also provides
                an unlabeled
                dataset of CT scans from 500 patients to support model training. Based on the extensive and
                comprehensive datasets, two
                sub-tasks will be held in SegRap2025:

                <li><strong>Task01</strong>: GTV Segmentation</li>
                <li><strong>Task02</strong>: LN CTV Segmentation</li>

                We believe that these algorithms will have the potential to support clinical manual delineation, enhance
                research on
                radiation dose calculation, and improve efficiency of radiotherapy treatment planning.
