A method, system and apparatus for surface rendering using medical imaging data is provided. A display device is controlled to render a first model of imaging data showing depth positions corresponding to a given surface threshold value, and further controlled to replace the first model with a second model of the imaging data showing respective depth positions corresponding to the given surface threshold value, the second model being faster to compute than the first model. The given surface threshold value is changed to an updated surface threshold value, for example using a slider input. The display device updates rendering of the second model to show updated respective depth positions corresponding to the updated surface threshold value. When an acceptance is received, the display device is controlled to replace the second model with the first model showing updated depth positions corresponding to the updated surface threshold value.

Methods and devices for identifying and defining a safety zone for restricting movement of a robotic arm in an operating room during a medical procedure are disclosed. The disclosed method utilizes medical navigation system, which receives an initiation input indicating initiation of defining of the safety zone. In response to receiving the initiation input, the system tracks an instrument and determines the location of the tracked instrument relative to a reference point. The system detects changes in the location of the tracked instrument until a termination input is received at the medical navigation system. The termination input indicates the termination of the defining of the safety zone. The system stores, in memory, change data indicative of the changes in the location of the tracked instrument. The data identifies the safety zone relative to the reference point.
