Description

X-ray imaging device {X-RAY IMAGING APPARATUS}

The present invention relates to an X-ray imaging device in which an X-ray source and an X-ray detector are disposed at both ends of a C-shaped arm.

An X-ray imaging device is a device that radiates X-rays to an object to be inspected, obtains an X-ray image from the X-rays passing through the object to be inspected, and displays the internal structure of the object to be inspected.

An example of such an X-ray imaging device is an X-ray fluoroscopy apparatus commonly referred to as a C-arm, which is used in an operating room, an emergency room, or during other clinical procedures. For example, a C-arm X-ray imaging device includes a movable mobile base, an articulated arm support connected to the mobile base, and a C-shaped arm connected to the arm support, and an X-ray source and an X-ray detector are mounted on both ends of the C-shaped arm, respectively, to take a perspective image of an object disposed therebetween.

Although this C-arm X-ray imaging device is intended to obtain a 2D fluoroscopic image, a tomography function is required to know the exact location of a lesion.

However, since the X-ray source is fixed to one end of the C-type arm in a general C-type X-ray imaging device, the entire C-type arm must be rotated to obtain a plurality of transmission images within a certain angular range. Therefore, a complex driving mechanism is required, shooting time is prolonged, precise control is difficult, and load burden and footprint increase due to the complex driving mechanism may be caused.

The present invention has been made to solve the above problems, and an object of the present invention is to provide an X-ray imaging device capable of linearly moving and rotating only an X-ray source invisible from the outside left and right with respect to a C-type arm.

In order to achieve the above object, an X-ray imaging apparatus of the present invention includes a C-type arm; a moving plate connected to one end of the C-shaped arm; a first driving unit for moving the moving plate left and right with respect to one end of the C-shaped arm; an X-ray source connected to the moving plate; a second driving unit for rotating the X-ray source left and right with respect to the moving plate; An X-ray detector is disposed at the other end of the C-shaped arm, and the X-ray source moves and rotates left and right by the first and second driving units to face the X-ray detector at all times.

In addition, in the X-ray imaging apparatus of the present invention, a support plate connected to one end of the C-shaped arm may be further included, and the first drive unit may move the moving plate left and right with respect to the support plate.

In addition, in the X-ray imaging apparatus of the present invention, the first drive unit may include: a lead screw connected to the support plate and disposed along a left-right direction; a nut connected to the moving plate and fastened to the lead screw; A first motor configured to rotate the lead screw in both directions may be included.

In addition, in the X-ray imaging apparatus of the present invention, the second driving unit may include a worm connected to the moving plate; A worm wheel connected to the X-ray source and engaged with the worm; It may include a second motor for rotating the worm in both directions.

In addition, in the X-ray imaging apparatus of the present invention, the second driving unit may include a second motor connected to the moving plate and rotating in both directions; A pulley connected to the X-ray source and connected to the second motor by a belt may be included.

In addition, the X-ray imaging apparatus of the present invention may further include a mounting frame on which the X-ray source is mounted, and the second drive unit may rotate the mounting frame left and right with respect to the moving plate.

In addition, in the X-ray imaging apparatus of the present invention, a movable mobile base; An arm support connecting the mobile base and the C-shaped arm may be further included.

According to the X-ray imaging apparatus of the present invention, the following effects are obtained.

Since only the X-ray source, which is invisible from the outside, can be moved and rotated horizontally and linearly with respect to the C-type arm, the imaging time is short, precise control is possible, and the overall driving mechanism is simplified, which can lead to weight reduction and footprint reduction.

In addition, it can be applied to Mammo (Mammography) for diagnosing breast cancer or EOX (Extra Oral X-ray) device for examining oral conditions by adopting and combining a mechanical structure that moves and rotates only the X-ray source left and right.
