Breast prone-to-supine deformation and registration using a Time-of-Flight camera

The surgical interventions of the breast are a delicate process where the surgeon must be very accurate. The patient is in supine position during the intervention, however the only resource that can be used is a Magnetic Resonance Image (MRI) taken in a different time and in prone position. The work presented in this paper develops a tool that transforms the prone MRI into a new virtual MRI corresponding to the position of the patient in the operating table. The position of the patient in the operating table is captured with a Time-of-Flight camera and the mechanical behavior of the breast is simulated using a biomechanical model that takes into account the different tissues that form the breast. The surgeon will have the pre-operative information adjusted to the position of the patient in the operating table making the intervention more accurate.
