Abstract

In radiotherapy, X-ray imaging and dose quality assurance is often carried out using physical phantoms, which simulate the X-ray attenuation of biological tissue. Additive manufacturing (AM) allows to produce cost-effective phantoms that can easily be adapted to different purposes. The aim of this work was to compare mechanical and X-ray attenuation properties of different materials, used in different AM technologies, machines, and materials. The average Hounsfield Units (HU) were measured by means of computed tomography (CT). The materials displayed tissue-equivalent CT numbers ranging from -104 HU to 1627 HU, showing a broad field of application for phantoms in radiotherapy.
