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： 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： The application as disclosed herein describes systems and methods for performing patient registration using a surgical navigation system. This application attempts to provide for improvements upon existing systems through the addition of refinement steps used to increase the accuracy of registration and streamline said process. In some cases the improvements generally involve the manipulation of spatial data in an iterative manner.

摘要： A training system for training a trainee to perform a surgical procedure on an anatomical region. The system includes a physical model of the anatomical region, a physical training instrument, a tracking system configured to track the location and orientation of the physical training instrument relative to the physical model, a display device, and a computer system. The computer system receives from the tracking system information indicating the location and orientation of the physical training instrument and generates and displays an augmented physical model and the physical training instrument. The display is updated based as the trainee manipulates the physical training instrument. After the trainee has completed the surgical procedure, the computer calculates a score based on the performance of the trainee. The score is a measure of the accuracy of the surgical procedure performed by the trainee or the duration of the surgical procedure.

摘要： A fiducial marker to be tracked by a surgical navigation system. The fiducial marker is to be affixed to an object during a surgical procedure. The fiducial marker including a casing for attachment to the object; a light emitting component attached to the casing; a power source within the casing; a signal receiver to receive a signal from the surgical navigation system; and control logic to control the light emitting component in response to the signal from the surgical navigation system. The object to-be-tracked may include a plurality of the fiducial markers arranged in geometric pattern, and the markers may include a first active fiducial marker having a first light emitting component that emits light having a first spectral bandwidth, and a second active fiducial marker having a second light emitting component that emits light having a second spectral bandwidth different from the first spectral bandwidth.

摘要： 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.

摘要： Navigation and simulation systems and methods for minimally invasive therapy in which the navigation system imports a planning method using patient specific pre-operative images. The navigation system uses intraoperative imaging during the medical procedure to update the preoperative images and provides images of tracked surgical tools along the surgical path prepared from the preoperative images.

摘要： Systems, methods and devices are provided for illuminating tissue with monochromatic or broadband light and imaging light that has been reflected back from the tissue. Imaging may be white-light imaging or hyperspectral imaging. The system can be a stand-alone hyperspectral imaging system, integrated as part of an external video scope, or as an auxiliary imaging module on an external videoscope. Various elements of a video scope that is particularly suited for minimally invasive surgery is first presented and then its configurations suitable for hyperspectral imaging are explained.
