Abstract:
We discussed the usefulness of fluorogram obtained using digital X-ray cineradiography (digital-cine-fluorograpy) in the diagnosis of dysphagia, comparied with that of video-fluorograpy. Digital-cine-fluorograpy produces five frames per second. A qualitative evaluation comfirmed that five frames per second was sufficient to grasp movement during swallowing in clinical setting. Digital-cine-fluorograpy imaging was also convenient for clinical practice in that the medical records can be accessed from any workstation. Although the maximum photography time (around 10 seconds) is limited and a higher exposure dose is required, we concluded that digital-cine-fluorograpy is a useful tool for the diagnosis of dysphagia.

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...

X-ray Diffraction of Biological Samples
According to Bragg's law, when X-rays strike the sample positioned on a stage, the rays are scattered by the electron clouds around the sample atoms. The X-ray diffraction or scattering is caused by constructive interference of the X-ray waves that reflect off the internal crystal...
Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
