Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail by referring to the following examples.
Fig. 1 is a schematic diagram of a digital radiography apparatus 100 according to a first embodiment of the present invention. As shown in fig. 1, the digital radiography apparatus 100 includes an image pickup unit 102, a display unit 106, an input unit 110, a control unit 104, and a collimator 114. The digital radiography apparatus 100 may further include an illumination unit (not shown). The illumination unit projects light toward the detector for indicating a projection range of X-rays on the detector (not shown) when the X-ray tube (not shown) is exposed. The object 107 is located between the X-ray tube and the detector, and the imaging unit 102 images a region where the object 107 is located. The display unit 106 displays the video of the area provided by the image pickup unit 102. In fig. 1, reference numeral 107 denotes an image of the subject captured by the imaging unit 102 on the display unit 106, rather than the subject itself, and for the sake of brevity of description, the subject is referred to herein. While viewing the display unit 106, the operator manipulates the input unit 110 and inputs the target range 112 corresponding to a portion of the area on the display unit 106. The input unit 110 is, for example, a mouse. The target range 112 may be rectangular, or other closed planar figure. The control unit 104 receives the target range 112 from the input unit 110, and the collimator 114 receives the target range 112 from the control unit 104 and adjusts the opening range accordingly. After the collimator 114 adjusts the opening range, the illumination range of the illumination unit is changed.
In the present embodiment, in order to facilitate the operation, before the input unit 110 inputs the target range 112 corresponding to a portion of the area on the display unit 106, the control unit 104 may acquire the opening range of the collimator 114 and cause the display unit 106 to display the corresponding initial range 108, and the input unit 110 may input the target range 112 by dragging the initial range 108.
The digital radiography apparatus 100 of the first embodiment can easily adjust the opening range of the collimator 114 to prevent the operator from entering or exiting the scanning room.
Fig. 2 is a flowchart of a method of adjusting an opening range of the collimator 114 of the digital radiography apparatus 100 according to the first embodiment of the present invention. The method 200 of adjusting the opening range of the collimator 114 of the digital radiography apparatus 100 includes step S202, step S204, step S208, and step S210.
In step S202, the imaging unit 102 images an area where the inspection object 107 is located.
In step S204, the display unit 106 displays the video of the area.
In step S208, the input unit 110 inputs the target range 112 corresponding to a part of the area.
In step S210, the collimator 114 adjusts the opening range of the collimator 114 according to the target range 112.
In the present embodiment, the method 200 of adjusting the opening range of the collimator 114 of the digital radiography apparatus 100 further includes step S206 for convenience of operation.
In step S206, before the target range 112 corresponding to a part of the area is input, the opening range of the collimator 114 is acquired and the corresponding initial range 108 is displayed. Step S208 is to input the target range 112 by dragging the initial range 108.
The method 200 for adjusting the opening range of the collimator 114 of the digital radiography apparatus 100 according to the first embodiment can conveniently adjust the opening range of the collimator 114, and avoid the operator from entering or exiting the scanning room.
Fig. 3 is a schematic view of a computed tomography apparatus 300 according to a second embodiment of the present invention. As shown in fig. 3, the computed tomography apparatus 300 includes an imaging unit 302, a display unit 306, an input unit 310, a control unit 304, and an examination couch 316. The computer tomography apparatus 300 further comprises an X-ray tube and a detector, with the object 307 to be examined being placed on the table 316 between the X-ray tube and the detector. The imaging unit 302 images an area where the inspection object 307 is located. The display unit 306 displays video of the area provided by the image capturing unit 302. As in the first embodiment, in fig. 3, reference numeral 307 denotes an image of the subject captured by the imaging unit 302 on the display unit 306 instead of the subject itself, and for the sake of brevity of description, the subject is referred to herein. While viewing the display unit 306, the operator manipulates the input unit 310 and inputs a tomographic range 312 corresponding to a part of the region on the display unit 306. In the present embodiment, the tomographic range 312 is a range determined by two broken lines in fig. 3. The input unit 310 is, for example, a mouse. The control unit 304 receives the tomographic scanning range 312 from the input unit 310. When performing the tomographic scanning, the couch 316 moves within a range corresponding to the tomographic range 312 under the control of the control unit 304.
The computed tomography apparatus 300 of the second embodiment can easily determine the moving range of the bed at the time of tomography and avoid the radiation dose caused by taking the scout image.
Fig. 4 is a flow chart of a method 400 of determining a range of movement of a couch 316 of a computed tomography apparatus 300 according to a second embodiment of the present invention. As shown in fig. 4, the method 400 of determining the movement range of the table 316 of the computer tomography apparatus 300 comprises step S402, step S404, step S406 and step S408.
In step S402, the imaging unit 302 images an area where the inspection object 307 is located.
In step S404, the display unit 306 displays the video of the area.
In step S406, the input unit 310 inputs or recognizes the tomographic range 312 corresponding to a part of the region.
In step S408, the movement range of the table 316 of the computed tomography apparatus 300 is determined from the tomographic range 312.
The computed tomography apparatus 300 of the second embodiment can easily determine the moving range of the bed at the time of tomography and avoid the radiation dose caused by taking the scout image.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
