Fluoroscopy apparatus and image display method therefor

摘要

Provided is a fluoroscopy apparatus including illuminating portions that radiate excitation light and illumination light onto an imaging subject; a fluorescence imaging portion that acquires a fluorescence image from fluorescence emitted at the imaging subject due to the irradiation with the excitation light; a return-light imaging portion that acquires a return-light image from return light returning from the imaging subject due to the irradiation with the illumination light; a display portion that displays the acquired fluorescence image and/or the return-light image; an identifying portion that identifies a region-of-interest in the fluorescence image; an image switching portion that switches the display on the display portion so that only the return-light image is displayed thereon when the region-of-interest R is not identified, and so that the return-light image and the fluorescence image are juxtaposed and displayed on the display portion when the region-of-interest has been identified.

主权项

1. A fluoroscopy apparatus comprising:
a light source configured to radiate excitation light and illumination light onto an imaging subject; a fluorescence image sensor configured to acquire a fluorescence image by capturing fluorescence emitted at the imaging subject due to the irradiation with the excitation light from the light source; a return-light image sensor configured to acquire a return-light image by capturing return light returning from the imaging subject due to the irradiation with the illumination light from the light source; a display configured to display the fluorescence image acquired by the fluorescence image sensor and/or the return-light image acquired by the return-light image sensor; and a processor comprising hardware, wherein the processor is configured to:
identify, in the fluorescence image, a region that includes a gradation value that exceeds a predetermined gradation-value threshold as a region-of-interest; andswitch the display on the display so that only the return-light image is displayed thereon in response to the region-of-interest being not identified, and so that the return-light image and the fluorescence image are juxtaposed and displayed on the display in response to the region-of-interest being identified, andwherein the processor is configured to switch the display on the display so that, in response to the region-of-interest being identified, information about the identified region-of-interest is displayed superimposed on the return-light image, and to control the display to display a prompt to an observer to make an input via an input device regarding whether or not observation is necessary for the region-of-interest corresponding to the displayed information, andwherein the processor is further configured to switch the display on the display so that the return-light image and the fluorescence image are displayed on the display in response to an input indicating that observation is necessary made via the input device.
