摘要： Deformation of mobile soft tissue is detected and represented in a three-dimensional medical image based on radiographically-detectable markers that are implanted in the tissue. Locations of the markers are co-registered with locations within the tissue. Sensed changes in relative locations of the markers are used to calculate relative changes in locations within the tissue due to deformation. The changes are used to calculate coordinated multi-voxel manipulations, such that a real-time volumetric medical imaging dataset is developed. By co-registering the operating room coordinate system and the volumetric medical imaging coordinate system, depth-3-dimensional augmented reality viewing of this real-time volumetric medical imaging dataset can be achieved, thereby improving the surgeon's understanding of underlying surgical anatomy and ultimately improving surgical outcomes.

摘要： A virtual object that represents a tangible object is displayed in a three-dimensional image. Responsive to a first input which may be movement of the tangible object, the virtual object moves within the three-dimensional image. Alteration of how the three-dimensional image is displayed occurs responsive to a second input. For example, virtual medical tools can be controlled by manipulating tangible tools to perform procedures and tasks virtually. Eye tracking can be used to generate variable angular resolution in the field of view in a head display unit with which the three-dimensional image is displayed. Digital objects may be used to cause the viewer's eyes move from feature to feature in a saccades fashion or a smooth tracking fashion.

摘要： Pointers are added to a 3D volumetric dataset to help the user visualize the direction of blood flow. A 3D volume containing at least one blood vessel is created. Next, the direction of the blood flow is determined. Next, at least pointer is placed into the 3D volume in an aligned fashion with the direction of blood flow such that the 3D volume is modified. Next, the modified 3D volume is displayed on a head display unit, such as an augmented reality or virtual reality display. Next, at least one pointer is advanced to a new position for additional modification of the 3D imaging volume.

摘要： A method for controlling operation of a CPAP apparatus. The apparatus has a blower, a patient interface, an air delivery conduit for delivering air from the blower to the patient interface, a sensor for determining the pressure in the patient interface, and a control mechanism that causes air to be delivered at a desired pressure to the patient interface and that detects transitions between inhalation and exhalation of a respiratory cycle of a patient in order to synchronise the blower output with the patient's efforts. In one form the CPAP apparatus provides pressure in accordance with a bi-level waveform with at least one characterizing parameter of the waveform being automatically adjusted in accordance with indications of sleep disordered breathing. The indications of sleep disordered breathing can be one or more of snoring, apnea, hypopnea, and flow limitation.

摘要： A self-tuning filter is disclosed. The self-tuning filter includes a digital clocking signal and an input coupled to the digital clocking signal, whereby the input reads a value incident on the input when the digital clocking signal changes to a predetermined state. A clock-tunable filter is, furthermore, coupled to the digital clocking signal so that the frequency of the clock-tunable filter is adjusted in relation to a sampling frequency at which the digital clocking signal operates. The self-tuning filter may be applied to an input of a data acquisition unit and applied to an input having a variable sampling frequency. A method of controlling the frequency of a clock-tunable filter is also disclosed.
