摘要：
[Problem ] To proviae a compact medical X-ray imaging apparatus which i s portable, with which it is possible to capture clear X-ray images while maintaining low radiation exposure, and with which it is possible to increase the life of X-ray sources. [Solution] An X- ray imaging apparatus which is portable, and with which it is possible to capture clear X-ray images while maintaming low radiation exposure. This compact medical X-ray imaging apparatus comprises: a carbon nanostructure triode cold cathode X-ray tube that radiates X-rays an X-ray image sensor that captures an image of X-rays that have passed through a patient a first detector that detects the X-ray radiation dosage and that is positioned between the carbon nanostructure triode cold cathode X -ray tube and the X-ray image sensor, and within the range in which X-rays are irradiated rather than the X-ray effective imaging area irradiated by the X-ray image sensor a second detector that detects the X-ray dose and is positioned in the center part of one side of the :frame of the X-ray image sensor a third detector that detects the X-ray dose and is positioned on one side of the :frame of the X - ray image sensor sandwiching the detection surfaces of the X-ray image sensor and facing the second detector a power supply which supplies a negative and a positive high-voltage pulse to the cathode and anode of the carbon nanostructure triode cold cathode X-ray tube respectively and an X-ray imaging control device which acquires detection data from the first, second and third detectors
