A hand-size structured-light three-dimensional metrology imaging system and method. The first conductive region is formed on a first plane spaced apart from a substrate by a first distance. The electron-emitting member is provided on the cathode electrode, and at least a portion of the electron-emitting member is exposed in the opening. The patient-specific cutting block includes a structure having a patient specific geometry corresponding to the model file of the patient, the structure configured to be connected to a portion of the fixing rod projecting from the bone in a unique coupling orientation. If the value of the type field indicates the data frame is a time-stamped frame, a timestamp field is inserted in the data frame.
