There is provided a radiation tomographic imaging apparatus and a radiation tomographic imaging method which allows the ECG information and the X-ray tube current value to be monitored while obtaining required projection data for the image reconstruction. The radiation tomographic imaging method for forming a tomographic image of a subject by means of the radiation from the radiation source comprises the ECG wave output step for measuring the heartbeat of the heart of the subject to output as the ECG wave signal; a variable output step for varying the radiation output based on the ECG wave signal; a determining step for determining the tomographic image reconstructed based on the projection data obtained by the radiation output having been varied is good or no good; and a displaying step for displaying the ECG wave signal, the radiation output, and the reconstruction data area for forming a tomographic image if the image is no good.
