Description

TECHNICAL FIELD [0001] The present invention relates to a radiation receiving module including a medical measurement device.

The present invention relates to a radiation receiver module in a digital radiography system, and more particularly, to a radiation receiver module, which has a long length and a large size such as a spine or a leg, Stitching function when photographing a hard-to-see part, and more particularly, to provide a simple photographing method for using an auto-stitching function for photographing a hard-to-see part, and more particularly, The present invention relates to a configuration of a device and a method of using the same which enable easy functioning based on an absolute position even when an auto-stitching function is implemented from an acquired image .

In general, clinical diagnosis is very important in medical practice, and non-invasive medical imaging methods using radiography are used as the most representative clinical diagnostic methods.

Especially, full spine x-ray is a typical test method to confirm scoliosis. Scoliosis can be judged by using Cobb method which measures the angle of scoliosis through an entire vertebral x-ray image.

In analogue radiology equipment using traditional film, imaging can be done at once with large 14 "x 36" cassettes and films for the entire vertebral X-ray, and multiple detectors Detector) is connected to the system to acquire X-ray images of all vertebrae in one shot.

However, this is not a generalized phenomenon due to the problem of physically overcoming the connection between the detector and detector, and the price problem. Therefore, in the acquisition of the entire vertebral x-ray image using the digital radiography equipment, A technique of completing a plurality of x-ray images into one image by using an auto-stitching function is mainly used, and in particular, feature-based registration, Landmark-based registration, and plain image-similarity measures.

Therefore, there is a method of utilizing a simple structure composed of a large acrylic plate, a ruler, a scaffold, etc. as a movable stand called a stitching stand or a stitching trolley for using a reference point-based registration method, It is possible to produce a result similar to the image output through the radiation receiving module with the medical measuring device according to the present invention.

However, in this method, since a separate stand is required to be installed at any time and off-set during movement installation may be changed, additional management is required. Which is difficult to automate.

As described above, there are three types of methods for controlling the motion of the radiation generator in the course of radiography. There are a method of moving the radiation generator vertically according to the movement of the radiation receiver, a method of changing the height of the radiation generator A method in which only the direction of the radiation generator is rotated in accordance with the movement of the radiation receiving unit, and finally, a method of moving the slit or the like is performed. In this case, the radiation generator is emitted toward the entire spine x- A method of sequentially imaging the cervical vertebra, the thoracic vertebra, the lumbar vertebra, and the like.

Also, in the method of moving and imaging the radiation generator as described above, various shooting methods such as a method of manually operating a human hand, a method of automatically moving the robot, and a method of automatically moving the robot when an area is set according to a program are used.

In the domestic prior art 10-1431781 x-ray imaging apparatus and its control method, particularly, in the photographing of the image for auto-stitching as described above, the subject image is photographed by the camera and is provided to the examiner. When the divided shooting area is designated while looking directly, the system is configured to automatically control the radiation generating unit to separately shoot an image and perform auto-stitching.

Particularly, in the above-mentioned prior art, in the conventional imaging method for auto-stitching, the user increases the work fatigue and the shooting time which occur in the process of directly designating the divided shooting region by moving the radiation receiving portion and the radiation generator, Difficulty in fine adjustment, and the like, and proposes a device that can be automatically controlled by inputting a shooting region while viewing a video as a solution to the problem.

However, in addition to the increase in cost due to additional devices such as a camera and an input unit, a calibration operation for eliminating an error between an imaging region specified by an image acquired by a camera and an actual X- And the effort is getting bigger.

SUMMARY OF THE INVENTION Accordingly, the present invention has been made to solve the above-mentioned problems of the prior art and to minimize the cost and effort to be put in. The object of the present invention is to provide a digital radiography system, It is easy to recognize the reference point and provides a convenient method for setting the entire shooting area and the divided shooting area, as well as providing a clear comparative point in auto-stitching from the radiographic image And to provide an effective method.
