Abstract: A method for performing auto-focus in a camera is disclosed. The method includes: receiving, from a tracking system for tracking a position of a medical instrument, a signal; determining, based on the received signal, that the medical instrument is removed from a field of view of the camera; in response to determining that a continuous auto-focus mode for the camera is enabled: retrieving, from a database, a first focus distance value representing a focus distance that was most recently set with intent for the camera; and automatically updating a focus distance of the camera to the first focus distance value.

Abstract: 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.

Abstract: Mechanisms for image processing are provided. A computing device comprises a memory, an input device, a display, and a processor. The processor is configured to: acquire a three-dimensional image of an anatomical structure and store it in the memory. The processor renders on the display (i) an initial volume of the three-dimensional image corresponding to an initial portion of the anatomical structure, and (ii) a moveable control element. The initial volume has an outer surface defined by a position of the control element. The processor receives input data updating the position of the control element relative to the initial volume; and renders on the display, in place of the initial volume, a further volume of the three-dimensional image, corresponding to a further portion of the anatomical structure and having a further outer surface defined by the updated position of the control element.

Abstract: A method of rendering medical image data includes: obtaining an image, having a plurality of voxels, of a volume of patient tissue having a plurality of tissue types; for each of the plurality of voxels: determining a first type indicator value indicating a likelihood that the voxel depicts a first one of the tissue types; storing the first type indicator value in association with the voxel; setting a first type indicator threshold for the first tissue type; rendering the image on a display and applying a first visual filter to a first subset of the voxels having type indicator values that satisfy the first type indicator threshold; and updating the rendering, responsive to receiving input data specifying a modified first type indicator threshold, to apply the first visual filter to an updated first subset of the voxels having first type indicator values that satisfy the modified first type indicator threshold.
