Method for calibrating working plane of medical detection apparatus

A method for calibrating a working plane of a medical detection apparatus, which is used for calibrating said working plane of said medical detection apparatus to be parallel with a first reference plane, wherein said working plane has a first point to be calibrated and a second point to be calibrated thereon, said first point to be calibrated serving as a first reference point and located on said first reference plane, and said first point to be calibrated and said second point to be calibrated are respectively supporting points of a first foot and a second foot on said working plane on said medical detection apparatus, the first foot and the second foot for supporting said working plane, said method for calibrating a working plane of a medical detection apparatus comprising:

• receiving at least one first inclination angle value from an angle measuring tool, wherein each first inclination angle value is an angle between a line connecting said first point to be calibrated and said second point to be calibrated and said first reference plane;
• computing a vertical distance between said second point to be calibrated and said first reference plane as a first magnitude of adjustment according to a pre-stored distance between said first point to be calibrated and said second point to be calibrated and the received first inclination angle value;
• and
• adjusting a height of said second foot according to said first magnitude of adjustment to allow said second point to be calibrated to be located on said first reference plane.
