FLUOROSCOPY APPARATUS AND FLUOROSCOPY APPARATUS OPERATING METHOD

摘要

The invention provides a fluoroscopy apparatus including an image-capturing device that acquires a fluorescence image of a subject; a sensitivity adjusting portion that sets a sensitivity of the image-capturing device to fluorescence on the basis of a gradation value of the fluorescence image; a notifying portion that extracts a lesion part from the fluorescence image acquired by the image-capturing device with the sensitivity set by the sensitivity adjusting portion and presents it to an operator; and a display switching portion that displays the fluorescence image on a display unit when the sensitivity in the image-capturing device is equal to or less than a predetermined threshold and that presents information showing the existence of the lesion part on the notifying portion when the sensitivity is greater than the predetermined threshold.

主权项

1. A fluoroscopy apparatus comprising:
an excitation light source that radiates excitation light onto a subject; a fluorescence-image acquisition portion including an image-capturing device that acquires a fluorescence image by capturing fluorescence generated in the subject by irradiating the subject with the excitation light from the excitation light source; a sensitivity adjusting portion that sets a sensitivity of the image-capturing device to the fluorescence on the basis of a gradation value of the fluorescence image acquired by the image-capturing device; a notifying portion that extracts a region having a gradation value higher than a predetermined gradation threshold value from the fluorescence image acquired by the image-capturing device with the sensitivity set by the sensitivity adjusting portion and that presents information showing the existence of the extracted region to an operator; a display unit that displays the fluorescence image acquired by the image-capturing device; and a display switching portion that displays on the display unit the fluorescence image acquired by the image-capturing device when the sensitivity set in the image-capturing device by the sensitivity adjusting portion is equal to or less than a predetermined sensitivity threshold and that presents the information using the notifying portion when the sensitivity is greater than the predetermined sensitivity threshold.
