## Abstract

The purpose of the present invention is to provide a method for obtaining a more effective 3D facial image for medical use. The present invention provides a medical imaging system includes a 2D surface image obtaining device including at least one camera for photographing a plurality of 2D facial images of an examinee, at different photography angles or ranges, a visual guidance configured to fix an examinee's line of vision, an X-ray radiography device for radiographing a 3D X-ray radiograph of the examinee's head, and an image synthesis unit for generating a 3D facial image by matching the plurality of 2D facial images with the 3D X-ray radiograph.

## Claims

### Claim 1

A medical imaging system, the system comprising:
a 2D surface image obtaining device including at least one camera for photographing a plurality of 2D facial images of an examinee;
an X-ray radiography device for radiographing a 3D X-ray radiograph of the examinee's head;
a visual guidance configured to fix an examinee's line of vision in front of the examinee; and
an image synthesis unit directly coupled to the 2D surface image obtaining unit and the X-ray radiography device to respectively receive the plurality of 2D facial images and the 3D X-ray radiograph and to generate a 3D facial image by matching the plurality of 2D facial images with the 3D X-ray radiograph.

### Claim 2 (depends on 1)

The system of claim 1, wherein said at least one camera photographs examinee at different angles or ranges.

### Claim 3 (depends on 1)

The system of claim 1, wherein the at least one camera includes a single camera moving and obtaining the plurality of 2D facial images.

### Claim 4 (depends on 1)

The system of claim 1, wherein the at least one camera includes a plurality of cameras located at different positions.

### Claim 5 (depends on 1)

The system of claim 1, further comprise:
a vision sensing means for sensing an examinee's line of vision.

### Claim 6 (depends on 5)

The system of claim 5, wherein the vision sensing means is configured to sense the examinee's line of vision until the photographing of the plurality of 2D facial images is completed.

### Claim 7 (depends on 1)

The system of claim 1, further comprising:
a base; and
a support column attached to the base, wherein the 2D surface image obtaining device and the visual guidance are located on the support column.

### Claim 8 (depends on 1)

The system of claim 1, wherein the X-ray radiography device, the 2D surface image obtaining device, and the visual guidance are housed in a self contained system.
