摘要： There is provided a method of accurately registering the position and orientation of inertial measurement units (IMUs) with respect to patient anatomy, whether in an operating room or other facility. A first IMU is mounted to a patient. A patient-specific registration tool is positioned against a portion of the patient anatomy in order to correctly engage the patient anatomy in only a single position and orientation that is known, and where the patient-specific registration tool includes a second IMU mounted thereto in a known position and orientation. Data is gathered from the first and second inertial measurement units while the patient-specific registration tool is stationary with respect to the patient to establish a known location of the second inertial measurement unit with respect to the patient anatomy. Subsequent changes in acceleration in three dimensions are tracked to calculate later positions and orientations in 3D. The present disclosure is directed to various aspects of orthopedics including bone and tissue reconstruction, patient-specific and mass customized orthopedic implants, gender and ethnic specific orthopedic implants, cutting guides, trauma plates, bone graft cutting and placement guides, patient-specific instruments, utilization of inertial measurement units for anatomical tracking for kinematics and pathology, and utilization of inertial measurement units for navigation during orthopedic surgical procedures. INTRODUCTION TO THE INVENTION It is a first aspect of the present invention to provide a surgical navigation system comprising a signal receiver communicatively coupled to a primary processor, the primary processor programmed to utilize a sequential Monte Carlo algorithm to calculate changes in three dimensional position of an inertial measurement unit mounted to a surgical tool, the processor communicatively coupled to a first memory storing tool data unique to each of a plurality of surgical tools, and a second memory

摘要： A calibration system is provided including an aperture layer, a lens layer, an optical filter, a pixel layer and a regulator. The aperture layer defines a calibration aperture. The lens layer includes a calibration lens substantially axially aligned with the calibration aperture. The optical filter is adjacent the lens layer opposite the aperture layer. The pixel layer is adjacent the optical filter opposite the lens layer and includes a calibration pixel substantially axially aligned with the calibration lens. The calibration pixel detects light power of an illumination source that outputs a band of wavelengths of light as a function of a parameter. The regulator modifies the parameter of the illumination source based on a light power detected by the calibration pixel.
