Description

Technical Field

[0001] The present disclosure relates to an information processing apparatus, a control method thereof, and a program.

Background Art

[0002] In recent years, the multifunctionalization of a radiation imaging apparatus that detects radiation such as X-rays as an electrical signal related to radiation image data has been studied. Imaging with a low dose of radiation such as X-rays is an issue in radiation imaging in the medical field, and one of the functions for solving this is automatic exposure control (AEC) of radiation. This automatic exposure control (AEC) is a function for detecting the integrated dose of radiation that has passed through a subject such as a patient, and stopping the irradiation of radiation by a radiation source when the detected integrated dose reaches an appropriate amount.

[0003] When performing automatic exposure control (AEC) using an FPD (Flat Panel Detector) as a radiation imaging apparatus, for example, a plate-shaped AEC detector separate from the FPD may be arranged so as to be sandwiched between the subject and the FPD. In recent years, there is a technology called built-in AEC in which an AEC detector is built into an FPD. The AEC detector measures the integrated dose of radiation that has passed through a subject in one or more preselected radiation detection regions (light collection fields) that detect the dose of radiation, and stops the irradiation of radiation when a predetermined appropriate amount is reached. Patent Document 1 discloses a technique for setting a light collection field to be used from a plurality of light collection fields.

Mode for Carrying Out the Invention

[0010] Hereinafter, embodiments (embodiments) for carrying out the present disclosure will be described with reference to the drawings. Note that the embodiments described below do not limit the scope of the claims, and not all combinations of the features described in the following embodiments are essential for solving the problems of the present disclosure.

[0011] (First Embodiment) First, the first embodiment will be described.

[0012] FIG. 1 is a diagram showing an example of a schematic configuration of an information processing apparatus 100 according to the first embodiment. As shown in FIG. 1, the information processing apparatus 100 includes a control unit 110, an operation input unit 120, and a display unit 130.

[0013] The control unit 110 comprehensively controls the operation of the information processing apparatus 100 and performs various processes based on information input from, for example, the operation input unit 120.

[0014] The operation input unit 120 is operated by, for example, a user and inputs information input from the user to the control unit 110.

[0015] The display unit 130 displays various types of information and various images, for example, based on the control of the control unit 110. In the present embodiment, the display unit 130 includes, for example, displaying a plurality of light-receiving fields for performing automatic exposure control (AEC) of radiation during the above-described radiation imaging.

[0016] Next, the internal configuration of the control unit 110 will be specifically described. As shown in FIG. 1, the control unit 110 includes an information acquisition unit 111 and a display control unit 112.

[0017] The information acquisition unit 111 shown in FIG. 1 acquires various types of information based on the information input from the operation input unit 120, for example. This information acquisition unit 111 has a light-receiving field display area information acquisition unit 1111 and a photographing site information acquisition unit 1112.

[0018] The light-receiving field display area information acquisition unit 1111 acquires information regarding a display area for displaying a plurality of light-receiving fields in the display unit 130. In the present embodiment, the light-receiving field display area information acquisition unit 1111 acquires, for example, information indicating the size of the display area as information regarding a display area for displaying a plurality of light-receiving fields in the display unit 130. This is to cope with the case where when setting the light-receiving fields to be used using an application or the like, it is not always the case that a plurality of candidate light-receiving fields are displayed on the entire screen of the display unit 130, but also when it is desired to display a plurality of candidate light-receiving fields in a part of the screen of the display unit 130. For example, it is assumed that a plurality of candidate light-receiving fields are displayed in a small display area such as a thumbnail, or a plurality of candidate light-receiving fields are displayed in a partial area within the screen arbitrarily designated by the user. In the present embodiment, the light-receiving field display area information acquisition unit 1111 may acquire, in addition to the information indicating the size of the display area, information indicating the resolution of the display area corresponding to the size of the display area as information regarding a display area for displaying a plurality of light-receiving fields.

[0019] The imaging site information acquisition unit 1112 acquires information regarding the site of the object (subject) for which the illumination field is to be set. In the present embodiment, the imaging site information acquisition unit 1112 acquires, for example, information regarding the imaging site which is the site of the object (subject) for which the above-described radiation imaging is to be performed. This is, for example, for the purpose of being able to display an elongated illumination field adapted to a finger when the imaging site desires to set the illumination field of the finger on the screen of the small display unit 130. Further, in order to switch the display forms of the plurality of illumination fields displayed by the display unit 130 according to the imaging site, it is preferable to associate the site of the imaging object (subject) with the illumination field setting display pattern so as to be able to cope with various sites. At this time, as a method of associating the site of the imaging object (subject) with the illumination field setting display pattern, it may be set in the system in advance, or the user may be allowed to select it each time.

[0020] The display control unit 112 shown in FIG. 1 performs display control on the display unit 130 based on the information obtained from the information acquisition unit 111 and the operation input unit 120. This display control unit 112 includes a display area determination unit 1121, an illumination field selection assist unit 1122, and a display size information update unit 1123.

[0021] The display area determination unit 1121 makes a determination regarding the display area based on the information regarding the display area for displaying the plurality of illumination fields acquired by the illumination field display area information acquisition unit 1111. Specifically, in the present embodiment, the display area determination unit 1121 makes a determination as to whether or not the size of the display area is equal to or greater than a predetermined size based on the information indicating the size of the display area for displaying the plurality of illumination fields acquired by the illumination field display area information acquisition unit 1111. Further, the display area determination unit 1121 may make the above-described determination in consideration of the information regarding the imaging site acquired by the imaging site information acquisition unit 1112 in addition to the information regarding the display area for displaying the plurality of illumination fields acquired by the illumination field display area information acquisition unit 1111.

[0022] The light-receiving field selection assist unit 1122 assists in setting, as the selection area of each of the plurality of light-receiving fields, an area wider than the area of each light-receiving field of the plurality of light-receiving fields displayed on the display unit 130 based on the determination result of the display area determination unit 1121. This is because it is assumed that it is difficult for the user to select the light-receiving field to be used when a plurality of light-receiving fields are displayed on the small display unit 130 or when they are displayed on a part of the display unit 130. To solve this problem, the peripheral area of the displayed light-receiving field is also set as the selection area of the light-receiving field. In addition, the light-receiving field selection assist unit 1122 may perform the above-described assistance also when selecting the light-receiving field of a local imaging site in consideration of the information on the imaging site acquired by the imaging site information acquisition unit 1112 in addition to the determination result of the display area determination unit 1121.

[0023] When the display size information update unit 1123, for example, receives an operation by the user to expand or contract the display area for displaying a plurality of light-receiving fields on the display unit 130, the display size information update unit 1123 performs a process of updating and displaying the information displayed on the display unit 130.

[0024] The display control unit 112 performs control to change the display form of the plurality of light-receiving fields displayed on the display unit 130 based on the information acquired by the information acquisition unit 111. Thereby, even when the size of the display area for displaying a plurality of light-receiving fields is different (when displaying on display units 130 with different sizes or when performing displays with different sizes on one display unit 130), the user can appropriately perform the selection operation of the light-receiving field to be used.

[0025] FIG. 2 is a flowchart showing an example of the processing procedure in the control method of the information processing apparatus 100 according to the first embodiment.

[0026] First, in step S201, when the user instructs, via the operation input unit 120, to start setting the light-receiving field used, for example, when performing the above-described automatic exposure control (AEC), the control unit 110 detects this instruction and starts the setting process of the light-receiving field to be used.

[0027] Subsequently, in step S202, for example, when the user designates a display area for displaying a plurality of daylighting fields on the display unit 130 via the operation input unit 120, the daylighting field display area information acquisition unit 1111 acquires information indicating the size of the designated display area. Here, an example in which the user designates a display area for displaying a plurality of daylighting fields has been described, but a form in which the system or the like automatically designates it may also be used. Hereinafter, a processing example of step S202 will be described with reference to FIG. 3.

[0028] FIG. 3 shows the first embodiment and is a diagram showing a processing example in the display unit 130 shown in FIG. 1. FIG. 3(a) shows a case where the user designates a display area for displaying a plurality of daylighting fields on the display unit 130 via the operation input unit 120, and the designated display area designated by the user is shown as a designated display area 310. Specifically, FIG. 3(a) shows an example in which the user performs a drag operation on a partial area of the screen of the display unit 130 to set the designated display area 310. Further, FIG. 3(b) is a diagram showing an example of a display form 320 in which a plurality of daylighting fields are displayed in the designated display area 310 set in FIG. 3(a). In the display form 320 shown in this FIG. 3(b), one rectangle 321 corresponds to one daylighting field.

[0029] Here, returning to the description of FIG. 2 again. Subsequently, in step S203, the display area determination unit 1121 determines whether or not the size of the display area for displaying a plurality of daylighting fields, which was acquired in step S202, is equal to or larger than a certain size based on the information indicating the size of the display area. Here, the certain size in step S203 corresponds to the "first size" in the present embodiment.

[0030] As a result of the determination in step S203, if the size of the display area for displaying a plurality of daylighting fields is equal to or larger than a certain size (equal to or larger than the first size) (S203 / Yes), the process proceeds to step S204.

[0031] When proceeding to step S204, the display area determination unit 1121 determines whether the size of the display area for displaying a plurality of daylighting fields, which is based on the information indicating the size of the display area obtained in step S202, is equal to or larger than a sufficient size. Here, the sufficient size in step S204 corresponds to the "second size" in the present embodiment, and this "second size" is larger than the above-described "first size".

[0032] As a result of the determination in step S204, if the size of the display area for displaying a plurality of daylighting fields is equal to or larger than the sufficient size (equal to or larger than the second size) (S204 / Yes), the process proceeds to step S205. When proceeding to step S205, the display control unit 112 generates data of a display form that shows a plurality of daylighting fields selected by the user as a plurality of continuous squares in a matrix, and that has a finer grid adjustment including more squares than that in S206 to be described later.

[0033] On the other hand, as a result of the determination in step S204, if the size of the display area for displaying a plurality of daylighting fields is not equal to or larger than the sufficient size (less than the second size) (S204 / No), the process proceeds to step S206. When proceeding to step S206, the display control unit 112 generates data of a display form that shows a plurality of daylighting fields selected by the user as a plurality of continuous squares in a matrix, and that has a coarser grid adjustment including fewer squares than that in S205.

[0034] FIG. 4 is a diagram showing a processing example of step S205 and step S206 in FIG. 2. Specifically, FIG. 4(a) is a diagram showing a processing example of step S205 in FIG. 2. That is, FIG. 4(a) shows a case where it is determined that the size of the display area (410) for displaying a plurality of daylighting fields is equal to or larger than a certain size (equal to or larger than the first size) in S203 and is equal to or larger than a sufficient size (equal to or larger than the second size) in S204. In the display form 410 shown in FIG. 4(a), one rectangle 411 corresponds to one daylighting field. Further, FIG. 4(b) is a diagram showing a processing example of step S206 in FIG. 2. That is, FIG. 4(b) shows a case where it is determined that the size of the display area (420) is equal to or larger than a certain size (equal to or larger than the first size) in S203 and is not equal to or larger than a sufficient size (less than the second size) in S204. In the display form 420 shown in FIG. 4(b), one rectangle 421 corresponds to one daylighting field. Specifically, the display form 410 shown in FIG. 4(a) is a display form in which a plurality of daylighting fields are shown by a plurality of rectangles 411 continuous in a matrix, and is a display form in which a fine grid adjustment including more rectangles is performed compared to the display form 420 shown in FIG. 4(b). Further, the display form 420 shown in FIG. 4(b) is a display form in which a plurality of daylighting fields are shown by a plurality of rectangles 421 continuous in a matrix, and is a display form in which a rough grid adjustment with fewer rectangles is performed compared to the display form 410 shown in FIG. 4(a). Note that the number of the matrix rectangles 411 in the display form 410 shown in FIG. 4(a) and the number of the matrix rectangles 421 in the display form 420 shown in FIG. 4(b) are merely examples and are not limited to those shown in FIG. 4.

[0035] Here, return to the description of FIG. 2 again. As a result of the determination in step S203, if the size of the display area for displaying a plurality of daylighting fields is not equal to or larger than a certain size (less than the first size) (S203 / No), the process proceeds to step S207. When the process proceeds to step S207, the display control unit 112 generates data of a display form in which a pattern-by-pattern adjustment is performed to show a plurality of daylighting fields, which are the objects selected by the user, by a plurality of discrete rectangles.

[0036] FIG. 5 is a diagram showing a processing example of step S207 in FIG. 2. Specifically, FIG. 5 shows a case where it is determined in S203 that the size of the display area (500) for displaying a plurality of light-receiving fields is not a size equal to or greater than a certain size (a size less than the first size). In the display form 500 shown in FIG. 5, one rectangle 510 corresponds to one light-receiving field. More specifically, the display form 500 shown in FIG. 5 is a display form in which preset pattern-by-pattern adjustment of a plurality of light-receiving fields is performed using a plurality of discrete rectangles 510-1 to 510-5. Note that the number of discrete rectangles 510 in the display form 500 shown in FIG. 5 is merely an example and is not limited to that shown in FIG. 5. Also, the arrangement of the discrete rectangles 510 in the display form 500 shown in FIG. 5 is merely an example and is not limited to that shown in FIG. 5.

[0037] Here, returning again to the description of FIG. 2. When the processing of step S205, step S206, or step S207 ends, the process proceeds to step S208. When the process proceeds to step S208, the display control unit 112 performs control to display, on the screen of the display unit 130, a plurality of light-receiving fields for performing, for example, the above-described automatic exposure control (AEC) in a display form based on the data of the display form generated in S205, S206, or S207.

[0038] After that, the user selects a light-receiving field to be used from among the plurality of light-receiving fields displayed on the screen of the display unit 130, and completes the setting process of the light-receiving field used, for example, when performing the above-described automatic exposure control (AEC). At this time, when the processes of step S205 and step S208 are performed, the display control unit 112 performs the setting process of the light-receiving field corresponding to the square 411 selected in the display form 410 shown in FIG. 4(a), for example. Similarly, when the processes of step S206 and step S208 are performed, the display control unit 112 performs the setting process of the light-receiving field corresponding to the square 421 selected in the display form 420 shown in FIG. 4(b), for example. Further, when the processes of step S207 and step S208 are performed, the display control unit 112 performs the setting process of the light-receiving field corresponding to the square 510 selected in the display form 500 shown in FIG. 5, for example. In the present embodiment, when the processes of step S207 and step S208 are performed, the function by the light-receiving field selection assist unit 1122 can be applied. Hereinafter, the function by the light-receiving field selection assist unit 1122 will be described with reference to FIG. 6.

[0039] FIG. 6 shows the first embodiment and is a diagram for explaining the function by the light-receiving field selection assist unit 1122 shown in FIG. 1. In this FIG. 6, the same components as those shown in FIG. 5 are denoted by the same reference numerals, and detailed descriptions thereof are omitted.

[0040] As shown in FIG. 6, similar to FIG. 5, a plurality of rectangles 510-1 to 510-5 corresponding to a plurality of lighting fields are illustrated. The lighting field selection assist unit 1122 calculates a region 611 wider than the region of the rectangle 510-1 as the selection region of the lighting field corresponding to the rectangle 510-1. Similarly, the lighting field selection assist unit 1122 calculates a region 612 wider than the region of the rectangle 510-2 as the selection region of the lighting field corresponding to the rectangle 510-2, and further calculates a region 613 wider than the region of the rectangle 510-3 as the selection region of the lighting field corresponding to the rectangle 510-3. Also, the lighting field selection assist unit 1122 calculates a region 614 wider than the region of the rectangle 510-4 as the selection region of the lighting field corresponding to the rectangle 510-4, and further calculates a region 615 wider than the region of the rectangle 510-5 as the selection region of the lighting field corresponding to the rectangle 510-5. The above-described calculation process by the lighting field selection assist unit 1122 is achieved, for example, by performing the following process. Specifically, the lighting field selection assist unit 1122 calculates a line connecting the centers 511 of the other rectangles 510 based on the center 511 of the rectangle 510. Next, the lighting field selection assist unit 1122 calculates the midpoint 621 of the line connecting the centers 511 of the two rectangles 510 and the midpoint 622 of the four sides of the screen 600 of the display unit 130 (or the four sides of a partial region of the screen displaying a plurality of lighting fields). Next, the lighting field selection assist unit 1122 connects the midpoint 621 and the midpoint 622 to divide the region within the screen 600, and calculates the selection regions 611 to 615 of the lighting fields corresponding to the rectangles 510-1 to 510-5, respectively. Then, the display control unit 112 sets the selection regions 611 to 615 calculated by the lighting field selection assist unit 1122 as the selection regions of the lighting fields corresponding to the rectangles 510-1 to 510-5, respectively. The user selects one of the selection regions 611 to 615 divided on the screen 600 of the display unit 130 by touching the screen 600 or clicking with a mouse. Then, the display control unit 112 sets the lighting field corresponding to the rectangle 510 included in the selection region selected by the user as the lighting field to be used.

[0041] In addition, in this embodiment, when a location at a certain distance from the rectangle 510 corresponding to the lighting field is selected by the user, a method of not setting the lighting field to be used is also applicable. Further, in this embodiment, when any boundary of the selection regions 611 to 615 is selected by the user, a method of setting the lighting field corresponding to the nearest rectangle 510 as the lighting field to be used is also applicable.

[0042] Next, after the screen display in step S208 of FIG. 2 is performed, the processing when the size of the display area for displaying a plurality of lighting fields is changed by the user will be described. After the screen display in step S208 of FIG. 2 is performed, if the size of the display area for displaying a plurality of lighting fields is changed by the user, for example, there is a risk that the resolution of the screen changes and the visibility and operability of the lighting fields by the user deteriorate. Therefore, when the lighting field display area information acquisition unit 1111 acquires information indicating the size of the new display area, the display control unit 112 performs control to change the display form of the plurality of lighting fields displayed by the display unit 130 based on the information indicating the size of the new display area. The processing of this display control unit 112 is performed, for example, by the display size information update unit 1123.

[0043] In the information processing apparatus 100 according to the first embodiment described above, a display unit 130 that displays a plurality of lighting fields for performing the above-described automatic exposure control is provided. And in the information processing apparatus 100 according to the first embodiment, information regarding the display area for displaying a plurality of lighting fields is acquired in the display unit 130 (S202 in FIG. 2). And in the information processing apparatus 100 according to the first embodiment, control is performed to change the display form of the plurality of lighting fields displayed by the display unit 130 based on the acquired information regarding the display area (S205 to S208 in FIG. 2). According to such a configuration, when a plurality of lighting fields are displayed and the user performs a selection operation of the lighting field to be used, it is possible to improve the visibility and operability of the lighting field by the user.

[0044] (Second Embodiment) Next, a second embodiment will be described. In the description of the second embodiment below, descriptions of matters common to the above-described first embodiment will be omitted, and matters different from the above-described first embodiment will be described.

[0045] The schematic configuration of the information processing apparatus according to the second embodiment is the same as the schematic configuration of the information processing apparatus 100 according to the first embodiment shown in FIG. 1.

[0046] In the above-described first embodiment, the display control unit 112 performs control to change the display form of a plurality of light collection fields displayed by the display unit 130 based on the information regarding the display area acquired by the information acquisition unit 111. In contrast, in the second embodiment, the display control unit 112 performs control to change the display form of a plurality of light collection fields displayed by the display unit 130 based on the information regarding the display area and the information regarding the imaging site acquired by the information acquisition unit 111.

[0047] FIG. 7 is a flowchart showing an example of a processing procedure in the control method of the information processing apparatus 100 according to the second embodiment.

[0048] In FIG. 7, the processes of steps S701 to S707 are the same as the processes of steps S201 to S207 shown in FIG. 2, respectively. At this time, in step S705 of FIG. 7, the "fine grid adjustment" in step S205 of FIG. 2 is described as "fine first grid adjustment". Also, in step S706 of FIG. 7, the "coarse grid adjustment" in step S206 of FIG. 2 is described as "coarse first grid adjustment". Further, in step S707 of FIG. 7, the "pattern-specific adjustment" in step S207 of FIG. 2 is described as "first pattern-specific adjustment".

[0049] In FIG. 7, when the process of step S705, step S706, or step S707 ends, the process proceeds to step S708. When the process proceeds to step S708, the display control unit 112 determines whether to perform light collection field display adjustment by site based on, for example, information input from the operation input unit 120.

[0050] If, as a result of the determination in step S708, the light-receiving field display adjustment is to be displayed by part (S708 / Yes), the process proceeds to step S709. When the process proceeds to step S709, the display control unit 112 determines whether the photographed part is a wide-area part or a local part of the subject (body) based on the information regarding the photographed part acquired by the photographed part information acquisition unit 1112. Here, examples of the wide-area part include parts of the torso such as the lung field. Examples of the local part include small and elongated parts such as the arm, hand, and finger. Note that the wide-area parts and local parts described here are merely examples and are not limited to the parts described here.

[0051] If, as a result of the determination in step S709, the photographed part is a wide-area part of the subject (body), the process proceeds to step S710. When the process proceeds to this step S710, since the photographed part is a wide-area part of the subject (body), it is assumed that the number of light-receiving fields to be displayed in the display area can be increased. When the process proceeds to step S710, the display control unit 112 generates data of a display form in which a second grid adjustment is performed to show a plurality of light-receiving fields as a plurality of continuous rectangles in a matrix, based on the information regarding the display area and the information regarding the photographed part acquired by the information acquisition unit 111. For example, when the process proceeds to step S710 after the process of step S705, the display control unit 112 generates data of a display form that maintains the fine grid adjustment in step S705. Also, for example, when the process proceeds to step S710 after the process of step S706, the display control unit 112 generates data of a display form that performs a finer grid adjustment than the rough grid adjustment in step S706. Also, for example, when the process proceeds to step S710 after the process of step S707, the display control unit 112 generates data of a display form that performs a rough grid adjustment similar to the rough grid adjustment in step S706.

[0052] Also, if as a result of the determination in step S709, the imaging site is a local site of the subject (body), the process proceeds to step S711. When proceeding to this step S711, since the imaging site is a local site of the subject (body), it is assumed that the number of light-receiving fields to be displayed in the display area has to be reduced. When proceeding to step S710, the display control unit 112 generates data of a display form in which second pattern-by-pattern adjustment is performed to show a plurality of light-receiving fields as a plurality of discrete rectangles based on the information on the display area acquired by the information acquisition unit 111 and the information on the imaging site. For example, when shifting to step S711 after going through the process of step S705, the display control unit 112 generates data of a display form in which pattern-by-pattern adjustment is performed with a larger number of rectangles than when shifting to step S711 after going through the processes of S706 and S707.
