Educational stereotactic interactive phantom

The concept of a new generation of educational anthropomorphic interactive phantoms providing virtual, physical and clinical simulation in functional neurosurgery, supporting various types of stereotactic equipment.

THE PROBLEMS

The design of anthropomorphic phantoms is tried to be close to human head anatomy and the work with them is the closest to the real conditions of stereotactic intervention for a surgeon. However, at the stage of performing stereotactic tomography of known anthropomorphic phantoms the surgeon receives a tomography of the phantom, which does not correspond to the real neuroimaging data of the human brain. Thus, the surgeon is not practicing the surgical planning principles that used in brain surgery - the selection of the required stereotactic target depending on the diagnosis and manifestation of the disease, planning instrument's dive path bypassing functionally significant areas of the brain and vessels. Functional stereotactic operation is not only a high-precision instrument penetration of the instrument into the required anatomical target, but also the surgeon's ability to select correctly brain structures (stereotactic targets) for exposure depending on the set clinical task as well as assessment of the efficacy of the intervention during the surgery.

OBJECTIVES

Development of a device for training young neurosurgeons to perform stereotactic surgery.

IMPLEMENTATION

We have developed a methodology for creating a new type of stereotactic feedback phantom, which is compatible with stereotactic equipment, allows interactive assessment of the effectiveness of the intervention during the training operation depending on the clinical task and allows the surgeon to work with the training data of human brain neuroimaging when planning the operation.

The phantom is based on the use of real human neuroimaging data, a prototype for phantom design, in the learning process, with the implementation of spatial linking of human neuroimaging data to the phantom's internal space.

Depending on the position of the stereotactic instrument in the intracranial space of the phantom, the decision unit provides information about possible clinical effects and side effects by evaluating the involvement of anatomical structures of the prepared neuroimaging training data in the simulated field of stereotactic treatment.

The technical result of using the phantom will be the training of the neurosurgeon to perform functional stereotactic interventions using various types of stereotactic devices in a variety of clinical tasks.
