METHOD AND DEVICE FOR ACQUIRING RADIATION EXPOSURE LEVEL, AND RADIOGRAPHIC IMAGING SYSTEM |
摘要 |
<p>In the case where radiological imaging of a subject to be injected with a contrast agent is preformed continuously, obtaining a more accurate radiation exposure dose of the subject. [Means for Solving the Problems] When obtaining, based on a radiation image signal of each frame detected by a radiation image detector through continuous radiological imaging of a subject to be injected with a contrast agent, a radiation exposure dose of the subject due to the continuous radiological imaging, identifying a frame which includes an image signal representing an image of the contrast agent as a contrast agent frame from the radiation image signal of each frame, and correcting the radiation exposure dose based on information of the contrast agent frame and obtaining a radiation exposure dose of the subject for the radiological imaging of the contrast agent frame.</p> |
