Abstract: A haptic system for enhancing the operator interface of winches and other automated stage systems, in particular in a theater, using an input control device which is provided with resistance based on the load on the winch and on other factors. The system detects the condition or state of the load and generates a response that is imparted to the input control device to provide the user with a tactile feedback of that condition.

Abstract: A method of generating intraoperative 3-dimensional image data includes the processes of acquiring baseline 3-dimensional image data of a region of interest. Non-contrast 3-dimensional image data of said region, and intraoperative 2-dimensional image data of said region are also acquired. The intraoperative 2-dimensional image data and the baseline 3-dimensional image data are each aligned to the non-contrast 3-dimensionsal image data, whereby an accurate rendering of intraoperative 3-dimensional image data results from the alignment of both the baseline 3D and intraoperative 2D image data to the non-contrast 3D image data.
