[Evaluation of the Distribution of Spatial Scattered Radiation Dose in Bedside Dynamic Chest Radiography].

Purpose: The purpose of this study was to determine the distribution of spatial scattered radiation during mobile dynamic chest radiography and to develop protective measures.

Methods: We measured the spatial scattered radiation, assuming both mobile chest radiography and mobile dynamic chest radiography. We placed the chest phantom on a stretcher.

Spatial Scattering Radiation to the Radiological Technologist during Medical Mobile Radiography.

Mobile radiography allows for the diagnostic imaging of patients who cannot move to the X-ray examination room. Therefore, mobile X-ray equipment is useful for patients who have difficulty with movement. However, staff are exposed to scattered radiation from the patient, and they can receive potentially harmful radiation doses during radiography.

Evaluation of novel X-ray protective eyewear in reducing the eye dose to interventional radiology physicians.

The new recommendation of the International Commission on Radiological Protection for occupational eye dose is an equivalent dose limit to the eye of 20 mSv year-1, averaged over a 5-year period. This recommendation is a drastic reduction from the previous limit of 150 mSv year-1. Hence, it is important to protect physicians' eyes from X-ray radiation.

An initial investigation of a wireless patient radiation dosimeter for use in interventional radiology.

Radiation exposure during interventional radiology (IR) procedures is a critical issue. We have developed a wireless real-time dosimeter for IR patients that use nontoxic phosphor (four sensors). We evaluated the basic performance parameters (such as dose linearity, batch uniformity, reproducibility, and wireless-communication conditions) of the developed system using an IR X-ray system.
