Scientists from Tomsk Polytechnic University are working on a technology for 3D-printing dosimetry phantoms, which present physical models of the human body or its single parts used by medical physicists for verification of radiotherapy plans. TPU scientists have developed a material which enables printing not conventional models but individual ones, taking into account the characteristics of a patient. It makes it possible to plan radiotherapy more clearly. The project is carried out in the close cooperation with the Tomsk Cancer Research Institute of Tomsk National Research Medical Center.

Dosimetry phantoms are applied prior each course of radiotherapy for verification of treatment plans. As a rule, they are conventional models of the human body or have a simple geometric shape. Modern phantoms are manufactured out of plastic approximate in density to the average index of different tissues of the body.

Senior lecturer Yuri Cherepennikov from the Division of Nuclear Fuel Cycle says: ‘There is no need to explain that radiotherapy is a serious medical manipulation associated with certain risks. The more carefully treatment plan is elaborated and verified, the more efficient it will be, the less
