Actual (reported)In Vivo Measurement of the Delivered Radiation Dose During Intraoperative Radiotherapy (IORT).
Assesses the absorbed radiation dose delivered to the tumor bed cavity during surgery. In vivo dosimetry measurements are recorded at two distinct anatomical locations relative to the spherical applicator surface: the south pole and the equator. Data will be reported as the mean value and standard deviation (SD) in Gray (Gy) for each measurement site.

Number of Participants With a Compliant Delivered Radiation Dose by Measurement Location.
Assesses treatment conformity relative to the prescribed dose of 20 Gray (Gy). A delivered dose is defined as compliant if it reaches at least 80% of the prescription (i.e., $\\ge$ 16 Gy). In vivo measurements are evaluated independently at two locations (south pole and equator). Data will be reported as the number (and percentage) of participants achieving this 16 Gy compliance threshold at each site.
