  • Santrauka [angl.]: The interest to application of 3D printing issues is growing up, since this technique might be used for the fabrication of differently shaped and very complicated objects, including medical phantoms and applicators. However, to produce any shape one needs to have 3D printer, object related printing algorithm and printing material, which is not tissue equivalent. Nearly tissue equivalent dose gels are known and used for a long time in high energy external radiotherapy for in situ dose assessment and as the phantoms - tumour imitators, for securing quality of the treatment procedure. When irradiated to high energy beams, free radicals created in the gel induce polymerization within restricted region thus forming volumetric shapes of the polymerized gels. The properties of polymerized gels depend on chemical components and their concentrations as well as on gel production technology and irradiation conditions. It is needed to notice that polymerized gel shapes are created inside the tightly closed vessel and are surrounded by gelatine matrix. Assessment of the created polymerized gel shape and dose distribution in it is usually performed taking the whole gelatine volume into consideration, thus contributing to the enhancement of measurement uncertainties and limiting their application in clinical field. The aim of this work was to develop ionizing radiation based 3D printing method for fabrication of nearly tissue equivalent free standing 3D dose gel medical phantoms (tumour imitators) having the size and shape of a real tumour. (Concept of this method was firstly proposed in our previous publication in 2015 [1]. Special dose gels (patent is pending) were used as printing material" for the processing of free standing dose gel shapes. There was no any request for a special 3D printing equipment or development of the additional object formation algorithm. Varying dose gel content and selecting radiation processing parameters of radiation treatment facility in accordance with a pre-planned cancer patient irradiation procedure, 3D shapes of the polymerized gel volume, corresponding to the real size of the irradiated (treated) volume were fabricated (3D printing) in gelatine. Polymerized gel volume (tumour imitator) representing free standing object was easily separated from the gelatine, thus making direct measurements of dose gel physical and chemical characteristics possible. Investigation results on these issues will be provided and discussed.
