Description of Virtual Phantom Dataset
The virtual phantom dataset may be downloaded as a single .zip file approximately 250 MB in size. The dataset includes all 10 virtual phantoms that may be used for the validation of deformable image registration in the head and neck region. Each virtual phantom is made up of two distinct DICOM image sets: a start-of-treatment (SOT) CT image set and an end-of-treatment (EOT) CT image set. When performing the deformable image registration with the intention of uploading the results to this website, the SOT image set should be designated as the primary (reference/fixed) image and the EOT image set should be designated as the secondary (target/moving) image. We will not be able to compute results for registrations performed in the opposite direction.
The initial publication describing the creation and use of the virtual phantoms may be found here.
The table below shows the characteristics of the patient cohort on which the virtual phantoms were based.
