1. A method for a surgical procedure simulation based on virtual reality (VR), the method being performed by a surgical procedure simulation apparatus and comprising:
receiving a computed tomography (CT) image of a body part of a subject of a surgical procedure;
placing the CT image of the body part in a 2D form into a virtual surgical space:
generating a stereoscopic image from the CT image of the body part;
generating a virtual three-dimensional (3D) body model corresponding to the body part from the stereoscopic image based on portions of the CT image having a Hounsfield unit (HU) value within a predetermined range; and
providing a surgical procedure simulation for spinal cord stimulation based on the virtual 3D body model,
wherein the providing of the surgical procedure simulation for spinal cord stimulation comprises:
outputting a virtual screen comprising the virtual 3D body model and a virtual C-arm apparatus;
virtually radiating virtual x-rays generated with a virtual x-ray generator at the virtual 3D body model configured as a set of data slices of the CT image virtually disposed between the virtual x-ray generator and a virtual x-ray sensor;
detecting at least one point in the 3D body model at which the virtual x-rays from the virtual x-ray generator meets a portion of the 3D body model based on sensing of the virtual x-rays by the virtual x-ray sensor;
generating a virtual X-ray image of the body part based on the detecting the at least one point:
outputting the virtual X-ray image to a virtual monitor included in the virtual C-arm apparatus;
providing a surgical procedure simulation of loss of resistance (LOR) using a syringe according to a selection of a user wearing the surgical procedure simulation apparatus within the virtual screen; and
providing, when the surgical procedure simulation of LOR is completed, a surgical procedure simulation for lead insertion into a virtual spinal cord part included in the virtual 3D body model.
