a first direction drive motor, which drives a pair of first-direction arranged shielding plates of the collimator to move in a first direction; and

a second direction drive motor, which drives a pair of second-direction arranged shielding plates of the collimator to move in a second direction.

3. The automatic collimator adjustment device as claimed in claim 1 , wherein the collimator control device comprises:

a rotation drive motor, which drives the collimator to rotate about a rotation axial direction.

4. The automatic collimator adjustment device as claimed in claim 1 , further comprising an image capture device connected to the processor unit.

5. The automatic collimator adjustment device as claimed in claim 1 , further comprising a display connected to the processor unit.

6. The automatic collimator adjustment device as claimed in claim 1 , further comprising an image data storage device, which is connected to the processor unit and stores therein the predetermined image pixel depth signal of the predetermined human body portion.

7. The automatic collimator adjustment device as claimed in claim 1 , comprising a touch display device connected via a touch panel connection interface to the processor unit, the touch display device comprising a touch panel and a display panel;

the touch panel being operated to pick up a selected human body area to generate the predetermined image pixel depth signal of the predetermined human body portion to the processor unit through the touch panel connection interface.

8. The automatic collimator adjustment device as claimed in claim 1 , further comprising a coordinate position marking device connected via a coordinate input interface to the processor unit;

the coordinate position marking device being operated to pick up a selected human body area to generate the predetermined image pixel depth signal of the predetermined human body portion to the processor unit through the coordinate input interface.

9. An automatic collimator adjustment method for a medical treatment equipment, in which the medical treatment equipment includes an X-ray source generator, a collimator, an X-ray detector, and an automatic collimator adjustment device, wherein the X-ray source generator projects an X-ray beam to a target human body and the X-ray detector detects the X-ray beam, wherein the automatic collimator adjustment device controls the collimator to adjust the X-ray beam projecting to a predetermined human body portion of the target human body, the method comprising the following steps:

(a) acquiring at least one instant image pixel depth signal of the target human body by a depth camera;

(b) receiving the at least one instant image pixel depth signal and comparing the at least one instant image pixel depth signal with a predetermined image pixel depth signal of the predetermined human body portion;

(c) if the at least one instant image pixel depth signal and the predetermined image pixel depth signal are different, generating, according to a difference between the at least one instant image pixel depth signal and the predetermined image pixel depth signal, at least one collimator adjustment signal to a collimator control device; and

(d) receiving the at least one collimator adjustment signal and then adjusting the collimator by the collimator control device to align the X-ray beam with the predetermined human body portion of the target human body.

10. The automatic collimator adjustment method as claimed in claim 9 , wherein in step (d), wherein adjusting the collimator by the collimator control device comprises the following steps:

(d1) driving a pair of first-direction arranged shielding plates of the collimator to move in a first direction; and

(d2) driving a pair of second-direction arranged shielding plates of the collimator to move in a second direction.

11. The automatic collimator adjustment method as claimed in claim 9 , wherein in step (d), wherein adjusting the collimator by the collimator control device comprises the following step:

(d3) driving the collimator to rotate about a rotation axial direction.

12. The automatic collimator adjustment method as claimed in claim 9 , further comprising pre-storing the predetermined image pixel depth signal in an image data storage device.

13. The automatic collimator adjustment method as claimed in claim 9 , further comprising picking up a selected human body area in a touch display device.

14. The automatic collimator adjustment method as claimed in claim 9 , further comprising picking up a selected human body area in a coordinate position marking device.
