Synopsis

Keywords: Multimodal, Radiotherapy, Synthetic CT, T2-w, softwareConventional coils for dose planning purposes cannot be placed on the patient as the outer body contour then will be deformed. Coils are therefore placed on a special holder which creates a distance between coil and patient, but this leads to less SNR. The blanket-coils are significantly lighter and can be placed directly on the patient. Three similarity comparison methods were used here, Hausdorff distance, Dice similarity coefficient (DSC) and Surface DSC. Eight of eleven comparisons were within 4 mm difference for Hausdorff distance; Surface DSC was >99%, at a 3 mm tolerance, and DSC >98.5%.
