This dataset contains segmentations for the RESECT dataset [1]. The tumor, resection cavity, cerebral falx, and sulci annotations can be freely used by research laboratories as well as clinical institutes. However, gaining any financial benefits from the distribution of the proposed annotation dataset is prohibited. If you use this data in your research, please cite the annotation dataset publication [2]. The dataset is published under the CC BY-NC-SA 4.0 License. - 2023-08-24 v0: initial upload - 2024-02-15 v1: update label storage format as 8 bits instead of 16 bits NOTE: this dataset is an extension of the labels used for the CuRIOUS 2022 MICCAI Challenge https://curious2022.grand-challenge.org, adding Cerebral falx and sulci labels to the tumor and resection cavity labels. For further research, please used this more comprehensive dataset. The corresponding RESECT ultrasound images are available at doi.org/10.11582/2017.00004 **For using the dataset, please cite the following publications:** Details for the RESECT database: [1] Y.
