Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a method of photographing a body of an examinee using an attitude guiding device and an attitude guiding device,

The present invention relates to an attitude-guiding device, and more particularly, to an apparatus and method for providing a recommended attitude information to a subject by displaying a posture to be taken by a subject using a light-emitting device in taking a medical image including X- .

X-ray imaging technology is one of the technologies that are widely used to acquire internal images of the human body in today's medical field. It is used to photograph the structure of the internal organs or teeth of the human body, In order to diagnose the disease.

In the X-ray radiography, a predetermined amount of X-ray beam is transmitted through the X-ray tube to the subject, the X-ray detector measures the amount of transmitted X-rays, calculates the X-ray absorption rate using the computer for the measured signal, Image reconstruction.

 As the region of the body where the X-ray is to be photographed is changed, the attitude of the subject with respect to the X-ray detector is different. In the case of X-ray photographing, the radiographer verbally describes the recommended posture for the patient (subject).

Korean Patent Publication No. 10-2015-0001178 (2015.01.06.)

It is difficult to accurately describe the recommended posture and the patient is having difficulty in understanding the recommended posture described by the radiologist in the current situation where the radiologist describes the recommended posture orally in the case of the patient (for example, a patient, etc.) There is a problem that it takes quite a long time to shoot. In addition, when the patient is a child or a foreigner, communication difficulties arise.

[

In the protocol storage unit 220 according to an embodiment of the present invention, a recommended posture to be taken by the subject according to a protocol for photographing a medical image (e.g., X-ray image) may be stored.

The recommended posture information for each photographing protocol stored in the protocol storage unit 220 is output through the posture information control unit 230 and the posture information control unit 230 outputs the recommended posture information for each of the LEDs of the light emitting unit 240 241 can be controlled. In other words, since the posture information control unit 230 generates light only for the LED 241 of the light emitting unit 240 corresponding to the position and direction in which the examinee takes a posture on the supporter 210, The position, direction, or size of the foot-shaped guide 242 displayed through the display unit 240 may be different from one another according to the shooting protocol.

Figs. 4A to 4E show the recommended posture information that the examinee should take a posture on the support in accordance with the photographing protocol. Fig. 4A to 4E, the recommended posture to be taken by the examinee depends on the imaging protocol. By guiding the foot shape with the posture guide device 200 according to the embodiment of the present invention, The subject can easily take a photographing posture in front of the X-ray imaging apparatus.

4A is a diagram of a protocol for photographing the subject's undergarment. As shown in FIG. 4A, when the KNEE (WB) photographing is performed, the subject can display the foot guide 242 to take a posture toward the back face, and when the LT KNEE STANDING AP photographing is performed, Shaped guide 242 may be displayed so as to face the front and to be biased to the right.

4B is a diagram of a protocol for photographing the subject's chest. As shown in FIG. 4B, when the LS SPINE LAT (UP) photographing is performed, the subject can display the foot guide 242 to face the right side face, and when the RT.C-SPINE oblique photographing The foot shape guide 242 can be displayed so that the examinee stands in the right oblique direction. On the other hand, when the LT.C-SPINE oblique photographing is being performed, the foot guide may be displayed so that the subject stands in the left diagonal direction as shown in FIG. 4C. In the case of the C-SPINE LAT photographing, A foot-shaped guide can be displayed so as to face the user.

Figs. 4D and 4E are diagrams showing protocols for photographing a shoulder of a subject. Fig. Shaped guide 242 may be displayed so that the subject is leaned to the left when proceeding with the photograph of the patient. When the LT SHOULDER AP photographing is carried out, the subject is guided by the foot-shaped guide 242 ) May be displayed. On the other hand, in the case of the RT.SHOULDER ARCH imaging, the foot-shaped guide 242 may be displayed such that the subject faces the back side in the left diagonal direction and in the case of the LT.SHOULDER ARCH imaging, the subject faces the back side and stands in the right diagonal direction .

The subject can align his / her foot with the foot-shaped guide 242 shown on the support 210 shown in FIGS. 4A to 4B to take a posture for photographing.

Meanwhile, the foot-shaped guide 242 displayed on the support table 210 can be variably adjusted in size according to the body information of the subject, and the body information according to an embodiment of the present invention includes sex, age, , And / or weight.

For example, when the subject is a child, the foot shape guide 242 may have a length of 15 cm to 18 cm and a width of 4 cm to 5 cm. On the other hand, in the case of an adult, the foot shape guide 242 may have a length of 26 cm to 28 cm and a width of 8 cm to 9 cm.
