Patent number: 10485507Abstract: A medical X-ray photographing apparatus includes a support, a support holder, a motor, a turning controller, an image processor, a light emitter, and a processor. The support is configured to turn an X-ray generator and an X-ray detector about a predetermined turning axis while holding the X-ray generator and the X-ray detector such that they face each other. In the apparatus, the light emitter is disposed on a virtual loop line surrounding the turning axis and includes a plurality of color LEDs. The processor is configured to control the light emitter in association with the turning of the support.
