Abstract. Beam’s Eye View (BEV) is an essential tool that is used by radiation therapists for planning radiotherapy treatment for cancer. It utilizes an algorithm that reconstructs a high resolution three-dimensional (3D) image by synergistically fusing serial composite images of the body, using both computed tomography (CT) and magnetic resonance imaging (MRI). Treatment planning using BEV allows better tumour localization and dose optimization while minimizing collateral damage to normal tissues. The current technology displays 3D images in a two-dimensional flat screen. In this paper, we introduced a 360 degree holographic display system to display the 3D BEV images that can potentially be used to facilitate radiotherapy treatment planning. Holography is a technique which enables 3D images to be displayed as holograms, and this can be generated using a number of methods. As shown in the paper, our holographic display system consists of a set of mirror plates, a rotating mirror plate, and a monitor controlled using our computer software via a computer. The hardware of the system is similar to the one presented in one of the references.
