Definitions
- the present invention relates to an X-ray imaging apparatus, and more particularly, to an X-ray imaging apparatus including an X-ray source unit, an X-ray sensor unit including a sensor panel provided with a plurality of X-ray sensors, and a panel moving unit. It's about doing.
- X-ray imaging apparatuses transmit a certain amount of X-ray flux to a body part to be photographed, and an X-ray sensor measures the amount of transmitted X-rays and records the measured data in a memory. The X-ray absorptivity of each point on the body imaging area is obtained, and the image is reconstructed.
- These X-ray imaging apparatuses include an X-ray light source and an X-ray detector, and the X-ray light source includes a generator for generating X-rays, and the X-ray detector detects X-rays and converts them into electrical signals. It is equipped with a sensor.
- a large sensor that is, a large area sensor, has a problem in that a manufacturing cost increases due to a long manufacturing process.
- the manufacturing cost of the X-ray imaging apparatus including the large area sensor is also increased.
- the present invention was devised to solve the above problems, and an object of the present invention is to provide an X-ray source unit, an X-ray sensor unit including a sensor panel including a plurality of X-ray sensors, and an X-ray including a panel moving unit.
- the present invention provides a photographing apparatus.
- An X-ray photographing apparatus detects an X-ray source unit for generating X-rays, an X-ray generated by the X-ray source unit and passed through an object, and comprises a sensor panel having a plurality of sensors. Included is an X-ray sensor unit and the X-ray sensor unit, including a panel moving means for moving the sensor panel.
- the X-ray imaging apparatus is a base for supporting an upper structure, a support pillar installed on the base, the elevating member is installed so that the lifting displacement in the vertical direction on the support pillar, connected to the lower portion of the elevating member
- the panel moving means moves the sensor panel in any one or more directions of up, down, left and right and diagonal.
- the panel moving means detects image data that the X-ray sensor unit cannot acquire due to the butting area by moving the sensor panel.
- the manufacturing cost is high.
- a plurality of small area X-ray sensors instead of using a large area sensor, it is possible not only to photograph a wide area as in the case of using the large area sensor, but also to reduce the manufacturing cost of the X-ray imaging apparatus. have.
- FIG. 1 is a block diagram illustrating an X-ray imaging apparatus according to an embodiment of the present invention.
- FIG. 2 is a view for explaining the X-ray sensor unit according to an embodiment of the present invention.
- FIG 3 is a view for explaining a sensor panel according to an embodiment of the present invention.
- jaw support member 500 rotary arm support member
- X-ray sensor unit 621 sensor
- FIG. 1 is a block diagram illustrating an X-ray imaging apparatus according to an embodiment of the present invention
- Figure 2 is a view illustrating an X-ray sensor unit according to an embodiment of the present invention
- Figure 3 is an embodiment of the present invention It is a figure explaining the sensor panel which concerns on an example.
- the X-ray imaging apparatus 1000 includes a base 100, a support pillar 200, a lifting member 300, a jaw support member 400, a rotation arm support member 500, and a rotation arm 600. ) And rotary arm drive means.
- the base 100 supports the support pillar 200 on which the components are installed, and the support pillar 200 is installed on one side of the base 100.
- the support member 200 is provided with the elevating member 300
- the elevating member 300 is provided with a control motor and the like can be moved in the vertical direction to adjust the height appropriately according to the height of the patient Can be.
- the jaw support member 400 is installed below the elevating member 300, the jaw support member 400 is a place where the jaw of the patient is located, the head of the patient on the X-ray imaging apparatus 1000 Location.
- a rotary arm support member 500 is connected to the upper surface of the elevating member 300 in the vertical direction, and the rotary arm support member 500 supports the rotary arm 600 by the rotary arm driving means. .
- the rotation arm 600 is an X-ray source unit 610 for generating X-rays and an X-ray sensor unit 620 for detecting X-rays generated by the X-ray source unit 610 and passed through the object Are arranged to face each other.
- the X-ray sensor unit 620 includes a sensor panel 622 having a plurality of sensors 621 and a panel moving unit 623.
- the plurality of sensors 621 are small-area sensors that sense X-rays, respectively, and the sensors 621 do not sense X-rays by the sensing region 621a that senses X-rays and the edge of the sensor, respectively. It is divided into a non-sensing area 621b that cannot be used.
- the sensors 621 are butted to form one large area sensor, and are attached to the front surface of the sensor panel 622. As a result, X-rays cannot be sensed on the front of the sensor panel 622 due to the gap and non-sensing area 621b generated by butting the sensing area 621a and the sensor 621 of each of the sensors 621. It is divided into a butting area 624.
- the X-ray sensor unit 620 should detect image data by sensing X-rays over the entire area where the sensing area 621a and the butting area 624 are combined.
- the panel moving means 623 is provided on the rear surface of the sensor panel 622 to detect data that is not obtained from the first image data 700.
- the panel moving unit 623 moves the sensor panel 622 in any one or more directions of up, down, left and right, and diagonal lines so as to photograph the X-ray sensor unit 620 of the first image data 700.
- the second image data 710 not overlapping the butting area 624 is detected.
- the first image data 700 and the second image data 710 are combined by a computer to correspond to the butting area 624 of the first image data 700. Is corrected to become completed image data 720.
- the X-ray imaging apparatus 1000 having the above components may detect complete image data using the plurality of small area sensors 621 without using a large area sensor having a high manufacturing cost, and may be manufactured.
- the manufacturing cost of the X-ray imaging apparatus 1000 may be reduced by using a plurality of sensors having a relatively low cost.
