Objective:
The purpose of this study was to introduce the use of a portable X-ray system by the staff members of a doctor helicopter (DH).
Methods:
From January 11 to 18, 2019, we were given temporary access to a portable X-ray system. This period is defined as the investigation term. During the investigation term, a medical chart review was retrospectively performed for all patients who were transported by the DH. We investigated the variables between cases in which an X-ray study had been performed (X-ray group) and had not been performed (control group).
Results:
Thirteen subjects were classified into the X-ray group, and 17 were classified into the control group. No X-ray studies were performed for patients who underwent interhospital transportation, and the proportion of cases involving patients with exogenous disease in the X-ray group was greater than that in the control group.
Conclusion:
We reported our experience of DH staff performing X-ray studies at the scene. Further studies are required to determine the indications for using portable X-ray systems in the prehospital setting.

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...

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...
