Radiation imaging apparatus and radiation image display method

A radiation image display method comprising:

• displaying, in a first view area, a first radiation image of an object captured from a first angle;
• displaying, in a second view area, a second radiation image of the object captured from a second angle different from the first angle;
• receiving an input in the first view area selecting the first radiation image;
• obtaining, in response to receiving the input selecting the first radiation image and an input to obtain a recaptured image, a third radiation image of the object that is different from and corresponds to the selected first radiation image by controlling a radiation imaging apparatus to move to a position corresponding to the first angle of the first radiation image, based on information included in the selected first radiation image, and recapture the selected first radiation image as the third radiation image, the third radiation image being captured from the first angle after receiving the input selecting the first radiation image;
• displaying the third radiation image in substitution for the first radiation image in the first view area in which the selected first radiation image is displayed, by replacing the first radiation image with the third radiation image;
• displaying an extension area in the first view area between the third radiation image displayed in the first view area and the second view area,
• displaying the selected first radiation image in the extension area;
• and
• displaying the first radiation image and the second radiation image in a different row.

A radiation imaging apparatus, comprising:

• a display unit configured to display a plurality of radiation images;
• a radiography module including a radiation source configured to emit radiation toward an object, and a radiation detector configured to detect radiation that has passed through the object and to output electric signals corresponding to the detected radiation;
• a radiation module driving unit configured to rotate the radiography module;
• and
• a control unit configured:
• to control the radiation module driving unit to control rotation of the radiography module to obtain radiation images of the object at different angles,
• to control the radiation source to emit radiation toward the object,
• to obtain the plurality of radiation images based on the electric signals output by the radiation detector, and
• to control the display unit to display the plurality of radiation images,
• wherein
• the display unit is configured to display a plurality of view areas including a first view area which includes a first radiation image of the object obtained at a first angle, and a second view area which includes a second radiation image of the object obtained at a second angle, and
• the control unit is further configured:
• to receive an input selecting the first radiation image,
• in response to the input in the first view area selecting the first radiation image and an input to obtain a recaptured image, to obtain a different radiation image that corresponds to the selected first radiation image by controlling, after the input selecting the first radiation is received, the radiography module to move to a position corresponding to the first angle of the first radiation image, based on information included in the selected first radiation image and to emit radiation toward the object to obtain the different radiation image at the first angle,
• to control the display unit to display the different radiation image in substitution for the first radiation image in the first view area in which the selected first radiation image is displayed, by replacing the first radiation image with the second radiation image,
• to control the display unit to display an extension area in the first view area between the different radiation image displayed in the first view area and the second view area,
• to control the display unit to display the first radiation image in the displayed extension area in the first view area, and
• to control the display unit to display the first radiation image and the second radiation image in a different row.
