摘要： A method, system and apparatus for image capture and registration are described. The method includes: obtaining a position of an imaging device in a tracking system frame of reference; obtaining a position of a patient in the tracking system frame of reference; determining, based on the position of the imaging device and the position of the patient, a transformation for registering an imaging device frame of reference with a patient frame of reference; receiving an instruction to capture an image, the instruction including coordinates identifying a target area in the patient frame of reference; applying the transformation to convert the coordinates to the imaging device frame of reference; and controlling the imaging device to capture an image based on the converted coordinates.

摘要： Methods and devices to track patient anatomy during a surgical operation. A patient reference device is attached to an anatomical feature of a patient and it includes an attachment base and an optically-trackable array detectable by an optical navigation system and having a longitudinally-extending arm to space apart the fixed geometric pattern from the anatomical feature. The arm includes a connector to be detachably secured to the attachment base. An inertial measurement unit within the attachment base enables determining, based on comparing a threshold level to a motion signal, that the attachment base has changed position, wherein the motion signal represents the change in position and its magnitude. Based on determining that the attachment base has changed position an alarm signal is generated an and an output device in the attachment base outputs an alarm in response to the alarm signal.

摘要： Systems and methods are provided for transforming a displayed three-dimensional image corresponding to a position and orientation of a field of view of an imaging probe. A three dimensional image of a tissue in a first co-ordinate space can be displayed. A field of view of an imaging probe in a second co-ordinate space can be configured, where the imaging probe has a plurality of transmitters removably connected to it, the transmitters operable to determine the position and orientation of the field of view relative to the positions of the transmitters in the second co-ordinate space. The first and second co-ordinate spaces can be co-registered, and the position and orientation of the field of view in the second co-ordinate space can be transformed to the first co-ordinate space. The three-dimensional image can be displayed to correspond to the transformed position and orientation of the field of view.

摘要： A system for adjusting an operating state of a medical electronic device is described. In an aspect, the system includes an optical tracking system configured to detect three or more tracking markers. The system also includes a processor coupled with the optical tracking system. The processor is programmed with instructions which, when executed, configure the processor to: configure an input command by assigning at least one operating state of the medical electronic device to a particular state of at least one of the tracking markers; after receiving a priming command, identify a present state of the tracking markers based on data from the optical tracking system; compare the present state with the particular state assigned to the operating state; and based on the comparison, determine that an input command has been received and adjust the operating state of the medical electronic device to the assigned operating state.

摘要： An image enhancement system and method for enhancing medical images from a surgical imaging system. Each image pixel has a value in a first three-dimensional color space. A mapping of values in a subset of the first color space is calculated to map each color point in the subset to an enhanced value. The mapping is calculated by selecting a reference point in the subset and, for each color point in the subset, mapping the color point to a modified color value offset from the reference point by the modified color point vector that has the same direction as the color point vector extending from the reference point to the color point, but a greater magnitude. The mapping is applied to the pixel values in the medical image falling in the subset to produce an enhanced image.

摘要： Systems and methods are provided in which devices that are employed during a medical procedure are adaptively configured during the medical procedure, based on input or feedback that is associated with the current state, phase or context of the medical procedure. In some example embodiments, the input is obtained via the identification of one or more medical instruments present within a region of interest, and this input may be employed to determine configuration parameters for configuring the device. In other example embodiments, the input may be based on the image-based detection of a measure associated with the phase or context of the medical procedure, and this input may be employed to adaptively control the device based on the inferred context or phase of the medical procedure. In other embodiments, images from one imaging modality may be employed to adaptively switch to another imaging modality.
