CROSS-REFERENCE TO RELATED APPLICATION(S) AND CLAIM OF PRIORITY

The present application is related to and claims the benefit of Korean Patent Application No. 10-2016-0092897, filed on Jul. 21, 2016, in the Korean Intellectual Property Office, the disclosure of which is incorporated herein in its entirety by reference.

TECHNICAL FIELD

The present disclosure relates to an X-ray apparatus and a method of operating the same, and more particularly, to an X-ray apparatus for providing a user with information regarding a position of an X-ray detector used for X-ray scanning and a direction in which the X-ray detector is mounted to a frame of the X-ray apparatus, and a method of operating the same.

BACKGROUND

An X-ray is an electromagnetic wave having a wavelength from about 0.01 to about 100 angstrom (Å) and can be used to obtain the internal structure of an object. Therefore, X-ray devices are widely used for photographing the inside of a living body or for common non-destructive industrial inspection.

The basic principle of a photographing device using X-rays is to transmit X-rays emitted by an X-ray tube (or an X-ray source) to a target object and detect a difference in the intensity of the transmitted X-rays via an X-ray detector and thus obtain the internal structure of the target object. When an X-ray apparatus includes a plurality of X-ray detectors, it is necessary for a user to check which of the X-ray detectors is mounted to a frame of the X-ray apparatus or a direction the corresponding X-ray detector is mounted to the frame of the X-ray apparatus.

In the embodiment shown in FIGS. 11A and 11B, the X-ray apparatus may display the status information icon 1130 regarding an X-ray detector on the display 1110 of the workstation 1100. Therefore, since a user may simply rapidly refer to positional information regarding the X-ray detector, color of light emitted by the X-ray detector, and the state information regarding the X-ray detector, the X-ray detector may be managed and controlled more efficiently.

FIGS. 12A through 12D illustrate diagrams for describing a method by which an X-ray detector according to an embodiment determines whether X-ray scanning may be performed according to a scan mode selected based on a user input.

Referring to FIG. 12A, the X-ray apparatus may display a user interface 1210 including a stand-type scan mode icon 1211, a table-type scan mode icon 1212, and a portable-type scan mode icon 1213 and may receive a user input for selecting any one of a stand-up type scan mode, a table-type scan mode, and a portable-type scan mode via the user interface 1210. In the embodiment shown in FIG. 12A, the X-ray apparatus may receive a user input for selecting the stand-type scan mode icon 1211. The X-ray apparatus may determine whether an X-ray detector 1220 is mounted to a stand-type mount 1230 according to the stand-type scan mode selected by a user. Since the method by which the an X-ray apparatus obtains current positional information regarding the X-ray detector 1220 is described with reference to FIGS. 4 through 8, detailed description thereof will be omitted.

An X-ray apparatus may determine whether X-ray scanning may be performed according to a scan mode selected based on a user input, based on the current position of the X-ray detector 1220. In the embodiment shown in FIG. 12A, the X-ray apparatus may determine whether the X-ray detector 1220 is currently mounted to the stand-type mount 1230 and determine that X-ray scanning may be performed according to the stand-type scan mode selected based on the user input.

The X-ray apparatus may display information regarding the determined X-ray scanning possibility in the form of a user interface 1210A. In the embodiment shown in FIG. 12A, the X-ray apparatus may display a scanning possible icon 1240.

Referring to FIG. 12B, an X-ray apparatus displays the user interface 1210 including the stand-type scan mode icon 1211, the table-type scan mode icon 1212, and the portable-type scan mode icon 1213 according to FIG. 12A and may receive a user input for selecting one of a stand-up type scan mode, a table-type scan mode, and a portable-type scan mode via the displayed user interface 1210. In the embodiment shown in FIG. 12B, the X-ray apparatus may receive a user input for selecting the table-type scan mode icon 1212. The X-ray apparatus may determine whether the X-ray detector 1220 is mounted to a table-type mount according to the table-type scan mode selected based on the user input.

The X-ray apparatus may determine that the currently sensed position of the X-ray detector 1220 is the stand-type mount 1230 instead of the table-type mount. Therefore, the X-ray apparatus may determine whether X-ray scanning may be performed according to the scan mode selected based on a user input, that is, the table-type scan mode, based on the current position and the mounting direction of the X-ray detector 1220. In the embodiment shown in FIG. 12B, the X-ray apparatus may determine that the X-ray detector 1220 is currently mounted to the stand-type mount 1230 and determine that X-ray scanning may not be performed according to the table-type scan mode selected based on the user input.

The X-ray apparatus may display a user interface 1210B that includes a scanning impossible icon 1250.

Referring to FIG. 12C, the X-ray apparatus may receive a user input for selecting the table-type scan mode icon 1212 via the user interface 1210 and, according to the table-type scan mode selected based on the received user input, may determine the current position of the X-ray detector 1220. According to an embodiment of the present disclosure, the X-ray apparatus may determine whether the X-ray detector 1220 is mounted to a table-type mount 1232.

In the embodiment shown in FIG. 12C, the X-ray apparatus determines that the currently sensed position of the X-ray detector 1220 is the table-type mount 1232 and X-ray scanning may be performed according to the table-type scan mode selected based on the user input. In this example, the X-ray apparatus may display the scanning possible icon 1240 on a user interface 1210C.

Referring to FIG. 12D, the X-ray apparatus may receive a user input for selecting the portable-type scan mode icon 1213 via the user interface 1210 and, according to the portable-type scan mode selected based on the received user input, may determine the current position of the X-ray detector 1220. According to an embodiment of the present disclosure, the X-ray apparatus may determine whether the X-ray detector 1220 is mounted to neither the stand-type mount 1230 (refer to FIGS. 12A and 12B) nor the table-type mount 1232.

In the embodiment shown in FIG. 12D, the X-ray detector 1220 may be mounted to the table-type mount 1232. Therefore, the X-ray apparatus may determine that the X-ray scanning may not be performed according to the portable scan mode selected based on the user input and display the scanning impossible icon 1250 on a user interface 1210D.

In the embodiment shown in FIGS. 12A through 12D, the X-ray apparatus displays whether the X-ray scanning may be performed according to a scan mode selected based on a user input by using the scanning possible icon 1240 or the scanning impossible icon 1250, thereby reducing effort of a user to determine a current position and a mounting direction of the X-ray detector 1220 and improving user convenience.

According to an embodiment of the present disclosure, when the X-ray apparatus receives a user input for selecting the stand-type scanning icon, the X-ray apparatus may determine whether the X-ray detector is mounted to a stand-type mount. Since the method by which the X-ray detector obtains positional information regarding a plurality of X-ray detectors is described above with reference to FIGS. 4 through 8, detailed description thereof will be omitted.

According to an embodiment of the present disclosure, the X-ray apparatus determines a direction in which an X-ray detector is mounted to a mount and displays information regarding the determined mounted direction with an icon including at least one of letters, numbers, symbols, and images.
