Complete metabolic response (CMR) for a patient with cholangiocarcinoma liver malignancy. Deformable PET images and corresponding calculated voxel survival fraction (VSF) and tumour control probability (TCP). a The deformably registered pre‐and post-treatment [18F] FDG PET images. The registration provided a one‐to‐one correlation between voxels on pre‐and post-treatment [18F] FDG PET images. b, c The estimated voxel SF and TCP. The survival fraction and TCP were calculated based on the 90Y absorbed dose and SUV volume histograms. The radiobiological parameters were derived from the generalised linear–quadratic (GLQ) fit (see Table 1)
