" ... RTsafe’s product, Personalized PseudoPatient, is a 3D-printed exact anatomical replica of the patient’s head. It is derived from the patient’s anonymous CT scan. It has the same bone structure and external surface as the real patient. The soft tissue is water based. Because it is derived from the patient’s CT scan, it is the closest to the real geometry of the patient. In fact, it is the only product in the market today that is based on real patient geometry. Moreover, the 3D-printed material and water are bone and brain tissue equivalent materials, respectively, in terms of radiological properties and physical density. There are ion chamber inserts that are placed by RTsafe into the phantom within the planning target volume (i.e., tumor or benign lesion) and the organs-at-risk of the patient. Ion chambers are placed within them by the medical physicist of the radiotherapy department and the deposited dose can be measured. All the steps of the radiotherapy chain such as set-up, image guidance, treatment delivery are done using the personalized phantom which reacts to radiation exactly like the real patient would. CBCT (Cone Beam Computed Tomography) images of the Personalized PseudoPatient are then spatially co-registered (fused) to the CT images of the real patient in order to verify the accuracy of the image guidance system and algorithms, as well as the positioning procedure. Last, a dosimetry report is created including qualitative and quantitative information that can be added to the medical record of the patient as patient-specific quality assurance verification. This procedure is a truly End-to-End quality assurance test that can verify the accuracy of the whole radiotherapy chain, from imaging to dose delivery. ... "
