    Maximal-safe resection of brain tumors improves patient outcomes, making accurate delineation of lesions from normal tissue critical.

  • 2

    Intraoperative ultrasound (iUS) offers real-time tumor detection and is more affordable than intraoperative MRI, but faces adoption challenges.

  • 3

    Factors like limited fields of view, learning curves, and imaging accuracy hinder the effective use of iUS in neurosurgery.

  • 4

    Current evidence shows iUS has a 72.2% sensitivity and 93.5% specificity for assessing glioma resection, indicating a need for improved accuracy.

  • 5

    The study aims to evaluate interobserver variation in iUS tumor boundary detection and explore bounding boxes as a simplified annotation method.
