[Research Report on the Consistency of Radiation Dose Structured Report (RDSR)].

In 2020, recording and management of exposure doses for computed tomography (CT) became mandatory. In terms of dose management, information regarding the imaged body part is particularly important information for proper tabulation. However, the actual body part to be imaged and the body part information obtained from the device may differ.

[Questionnaire Survey of Radiation Protection Education in Hospitals].

Purpose: The present study aimed to investigate the current situation of radiation protection education for designated radiation workers in hospitals.

Methods: A web-based questionnaire survey was conducted at 1,883 hospitals nationwide with 200 or more beds.

Results: Responses from 186 hospitals were included in the analysis.

A JROD survey: nationwide overview of radiotherapy data from 2015 to 2021.

The purpose of this survey was to examine the status of radiotherapy in Japan based on the cases registered in the Japanese Radiation Oncology Database (JROD), from 2015 to 2021, and to provide basic data to help improve the usefulness of the JROD in the future. The study population consisted of patients who underwent radiotherapy between 2014 and 2020 and did not opt out of the study. The survey item data analyzed in this study were entered into the database at each radiotherapy institution by referring to medical records from the preceding year.

Japanese structure survey of radiation oncology in 2015.

This article describes the ongoing structure of radiation oncology in Japan in terms of equipment, personnel, patient load and geographic distribution to identify and overcome any existing limitations. From May 2016 to August 2018, the Japanese Society for Radiation Oncology conducted a questionnaire based on the Japanese national structure survey of radiation oncology in 2015. Data were analyzed based on the institutional stratification by the annual number of new patients treated with radiotherapy per institution.

Japanese structure survey of radiation oncology in 2013.

This paper describes the ongoing structure of radiation oncology in Japan in terms of equipment, personnel, patient load and geographic distribution to identify and overcome any existing limitations. From December 2014 to July 2017, the Japanese Society for Radiation Oncology conducted a questionnaire based on the Japanese national structure survey of radiation oncology in 2013. Data were analyzed based on institutional stratification by the annual number of new patients treated with radiotherapy per institution.

[Analysis of Workflow and Structuring of the Problem Element for Workflow Database Construction of Radiological Technologists in Radiation Therapy].

The work of radiological technologists is changing and more complicated because of the development of medical technology and implementation of information technology (IT). Although the cases of incident and accident have been reported, they have not been comprehensively analyzed in the workflow for radiotherapy. In this study, we visualized the workflow of radiological technologists in radiotherapy and revealed the causes of incidents and accidents.

[Survey of the Requested Function for Quality Assurance System for Images (Kenzo System)].

As the use of filmless examination images, using various systems, has increased, and became common to perform KAKUTEI and save the images. In particular, the use of quality assurance system for images (Kenzo system) has increased to ensure the efficient performance of confirmed image. However, there has been no report showing what kind of function should be used or how to write the specifications of such a function in introducing the Kenzo system.

AUTOMATIC ACQUISITION OF CT RADIATION DOSE DATA: USING THE DIAGNOSTIC REFERENCE LEVEL FOR RADIATION DOSE OPTIMIZATION.

The present work describes that we try to construct a system that collects dose information that performed CT examination from multiple facilities and unified management. The results of analysis are compared with other National diagnostic reference level (DRL), and the results are fed back to each facility and the cause of the abnormal value is investigated for dose optimization. Medical information collected 139 144 tests from 33 CT devices in 13 facilities.

Development of Clinical Database System Specialized for Heavy Particle Therapy.

We have developed a data archiving system for study of charged particle therapy. We required a data-relation mechanism between electronic medical record system (EMR) and database system, because it needs to ensure the information consistency. This paper presents the investigation results of these techniques.

Development and practice of ISMS at a Radiotherapy Hospital by using IHE Integration profiles.

Our hospital is specialized for radiation therapy and has many information devices. Various job categories are working. When we implemented an EMR, we aimed to enforce ISMS by using IHE profiles.

Construction of the radiation oncology teaching files system for charged particle radiotherapy.

Our hospital started the charged particle therapy since 1996. New institutions for charged particle therapy are planned in the world. Our hospital are accepting many visitors from those newly planned medical institutions and having many opportunities to provide with the training to them.

Geographical distribution of radiotherapy resources in Japan: investigating the inequitable distribution of human resources by using the Gini coefficient.

This is a pilot study that aims to elucidate regional disparities in the distribution of medical resources in Japan. For this purpose, we employed the Gini coefficient (GC) in order to analyze the distribution of radiotherapy resources, which are allocated to each prefecture in Japan depending on the size of its population or physical area. Our study used data obtained from the 2005 and 2007 national surveys on the structure of radiation oncology in Japan, conducted by the Japanese Society for Therapeutic Radiology and Oncology (JASTRO).

[Survey on medical information education for radiologic technologists working at hospitals].

Recently, the importance of medical information for radiologic technologists has increased. The purpose of this questionnaire survey was to clarify the method of acquiring skill in medical information for radiologic technologists from the point of view of the managers of radiology departments. The questionnaire was sent to 260 hospitals that had introduced picture archiving and communication systems (PACSs) for the person responsible for medical information in the radiology department.

[Investigation of practical method for quality assurance and control of medical displays].

Quality assurance (QA) guidelines for medical display systems in Japan, JESRA X-0093, were published in August 2005 and have been used in many medical fields to maintain image quality on medical displays. This report offers detailed explanations of terms and testing methodologies in the guidelines, taking into account users with little knowledge of display technology. The management grade classifications, luminance meters, test patterns, and evaluation methods for executing the QA are supplementally described based on the technical background of related things.

[A survey of medical information education in radiological technology schools].

The purpose of this study was to clarify actual conditions and problems in medical information education and to propose the educational concept to be adopted in medical information. A questionnaire survey was carried out by the anonymous method in June 2008. The survey was intended for 40 radiological technology schools.
