Production approaches of a human brain tissue phantom for robot-assisted stereotactic biopsy

Abstract

Abstract The article presents the production approaches of a human brain tissue phantom for robot-assisted stereotactic biopsy. The different types of materials used for the production of brain phantoms are shown. The experiments on the possibility of obtaining a sample of tissue simulating the brain, using a conventional biopsy needle with a side cutting window, are conducted. It is proved that silicone can not be used for production of a phantom of a brain tumor. The approach to the production of a phantom of two materials is proposed for use in the development of new robotic systems of stereotactic brain biopsy, as well as training surgeons.
