In the time of will photographing to a certain position of patient body, the radiation doctor adjusts the height of the DR detector on the column according to patient's height and position.Open the indicator cock of light concentrator on the bulb again.Adjust the height of bulb, make the display lamp cross centre line point to the center (centering) that to photograph, press the exposure button of high tension generator then, allow bulb produce X ray.X ray passes patient and need photograph and by the DR detector X ray of record patient information is changed into the signal of telecommunication behind the position.By image workstation the signal of telecommunication is reconstructed into the image at a width of cloth patient body position,, and can becomes image print or imprinting CD to preserve for diagnosis.Existing centering mode is estimated display lamp cross hairs position that centrally aligned is photographed by pressing the lifting button of bulb, and moving both vertically up and down of bulb and DR detector is uncorrelated mutually, produces following problem thus:

A) because there is error in range estimation display lamp cross hairs so operate at every turn, the central point of image not necessarily need be taken the central point at position;

B) owing to the doctor earlier sets patient location before the DR detector after, adjust the position height of bulb again, need for a long time like this, both influence diagnosis and take quantity, the while also increases doctor's workload;

C) because the very difficult bulb that guarantees is aimed at the DR detector, cause the image lack of homogeneity.
