Visualization of the tumor cavity after lumpectomy of breast cancer for postoperative radiotherapy Ilja F. Ciernik, Anja M. Greiss Clinical and Translational Radiation Oncology Volume 14, Pages 47-50 (January 2019) DOI: 10.1016/j.ctro.2018.11.003 Copyright © 2018 Terms and Conditions

Fig. 1 Assessment of visibility of SAIB/X-SAIB for radiotherapy planning on a phantom. Different amounts of SIAB/x-SIAB were applied (a) over a length of 5 cm on a paper carrier with the fingertip loaded with (from left to right) with 50 mikroL, 40 mikrolL, 30 mikroL, 20 mikroL or 10 mikroL. (a) shows a plain X-ray of the marker, (b) the axial imaging on a planning CT at a slice thickness of 3 mm, (c) a digitally reconstructed radiograph, and (d) segmentation of the liquid tissue marker.

Fig. 2 Contrast-enhanced visualization of the tumor cavity following lumpectomy with SIAB/x-SIAB. Scans shown are gated from (−132)–(−124) to (201)–(225) Hounsfield units. Patients underwent tumor excision and adjuvant EBRT (a to g), or tumor excision followed by oncoplastic surgery (h to k). Patients in c, g, and kwere treated in prone position. Figures a1…k1 indicate the unprocessed imaging data. Manual segmentation target structure definition is shown in a2…k2 (white line). Figures a3…k3 show the digital reconstructed radiograph with the horizontalline passing trough the target structure (white) and the corresponding axial sections.
