Abstract
The application discloses a well plate calibrator, a data measurement method and a computer tomography instrument calibration method. The well plate calibrator comprises a base and at least three calibration plates; the at least three calibration plates are vertically arranged on one side of the base, and the calibration plates are radially arranged with the center of the base as a reference; the calibration plate is provided with n through cylindrical holes, and each cylindrical hole is located at different positions of the calibration plate; the connecting line between every three cylindrical holes constitutes m positioning lines, the extension directions of the positioning lines are different, and n and m are greater than 1. The application can realize the traceability and calibration of the detection accuracy of CT equipment, and meet the calibration requirements of the current CT equipment.
