摘要： A system for assisting a surgeon to perform an operation on a patient where surgeon employs a first surgical instrument that has a shaft and a tip. The system include a video capture device configured to capture real-time video data showing the first surgical instrument while the first surgical instrument is being used by the surgeon to perform the operation. The system also includes a display device and a computer processor. The computer processor is configured to receive real-time video data from the video capture device as a sequence of digital image frames and, for each image frame, analyze the image frame to determine the location in the image frame of the shaft of the first surgical instrument, process the image frame to overlay received overlay information on the shaft of the first surgical instrument as it appears in the image frame, and display the processed image frame on the display device.

摘要： A magnetic resonance (MR) imaging system includes a transmit radio frequency (RF) coil assembly comprising multiple capacitor banks each coupled to at least one diode that is characterized by a high breakdown voltage such that when the transmit RF coil assembly applies at least one slice-selecting RF pulse to a portion of a subject placed in the magnet to select a particular slice for MR imaging, the capacitor banks are selectively adjusted to improve an RF transmission characteristics of the RF coil assembly in transmitting the at least one slice-selecting RF pulse. The MR imaging system may further include a receive radio frequency (RF) coil assembly configured to, in response to at least the slice-selecting RF pulse, receive at least one response radio frequency (RF) pulse emitted from the selected slice of the portion of the subject; a housing; a main magnet; gradient coils; and a control unit.

摘要： Methods and apparatuses for performing patient registration. 3D scan data from a 3D scanner, preoperative image data, first tracking data from a first tracking system, and second tracking data from a second tracking system are mapped to a common coordinate space. The 3D scan data and the first tracking data are mapped to each other using a transformation that is determined based on a calibration relating the 3D scan coordinate space and the tracking coordinate space. The 3D scan data and the preoperative image data are mapped to each other using a surface matching algorithm. The first tracking data and the second tracking data are mapped to each other based on tracking of the patient reference device.

摘要： The present disclosure reports on a method to first determine the required electromagnetic stream function, and then iterate on the contouring of the stream function to optimize the force, torque, shielding, and/or mutual inductance of the design after-the-fact without compromising the electromagnetic performance and an electromagnetic coil manufacture according to the method. These parameters are sensitive to the precise positioning of the discrete wires.

摘要： Methods and systems for providing feedback during a medical procedure are provided. A saved optical image of a field of view (FOV) of a site of the medical procedure is obtained along with a live optical image of the FOV of the site during the medical procedure. Navigational information relative to the site of the medical procedure is determined. The navigational information is then mapped to a common coordinate space, to determine the navigational information relative to the FOV of the saved and live optical images of the surgical site. Virtual representations of the navigational information is overlaid on the saved and/or live optical images and displayed on at least one display.
