Development of an Eye-Tracking Image Manipulation System for Angiography: A Comparative Study.

Rationale And Objectives: Appropriate image manipulation of angiographic image display systems during interventional radiology is performed by radiological technologists and/or nurses given instructions from radiologists. However, appropriate images might not be displayed because of communication errors. Therefore, we developed a manipulation system that uses an eye tracker.

Establishing community-based integrated care for elderly patients through interprofessional teamwork: a qualitative analysis.

Background: Working in multidisciplinary teams is indispensable for ensuring high-quality care for elderly people in Japan's rapidly aging society. However, health professionals often experience difficulty collaborating in practice because of their different educational backgrounds, ideas, and the roles of each profession. In this qualitative descriptive study, we reveal how to build interdisciplinary collaboration in multidisciplinary teams.

Problem-based learning for radiological technologists: a comparison of student attitudes toward plain radiography.

Background: Knowledge and skill expected of healthcare providers continues to increase alongside developments in medicine and healthcare. Problem-based learning (PBL) is therefore increasingly necessary in training courses for radiological technologists. However, it is necessary to evaluate the effects of PBL to completely introduce it in our education programs.

[A pilot study of contrast medium dose reduction using low tube voltage and iterative reconstruction: computed tomography angiography of the head].

This study aimed to reduce contrast medium dose without reducing the diagnostic capability of computed tomography (CT) angiography of the head. We evaluated the advanced statistical iterative reconstruction (ASiR) settings to adjust to low tube voltage CT. A syringe phantom was constructed using dilute contrast medium and was imaged at tube voltages of 80-120 kV.

[An introduction and implementation of problem-based learning for radiography positioning training].

The knowledge of radiological technologists is expected to increase with medical development. However, it is impossible to impart all knowledge in a limited time frame. Problem-based learning (PBL) is a learning methodology to solve it.

[Development of an attitude-measurement questionnaire using the semantic differential technique: defining the attitudes of radiological technology students toward X-ray examination].

Background: In general, it is difficult to objectively evaluate the results of an educational program. The semantic differential (SeD) technique, a methodology used to measure the connotative meaning of objects, words, and concepts, can, however, be applied to the evaluation of students' attitudes. In this study, we aimed to achieve an objective evaluation of the effects of radiological technology education.

A pilot study measuring changes in student impressions before and after clinical training using a questionnaire based on the semantic differential technique.

Students with a positive impression of their studies can become more motivated. This study measured the learning impact of clinical training by comparing student impressions before and after clinical training. The study included 32 students of radiological technology in their final year with the Division of Radiological Science and Technology, Department of Health Sciences, School of Medicine, Hokkaido University.

Care-seeking behavior of Japanese gynecological cancer survivors suffering from adverse effects.

Background: Post-treatment follow-up visits for gynecological cancer survivors should provide opportunities for management of adverse physical/psychological effects of therapy and early recurrence detection. However, the adequacy of such visits in Japan is poorly documented. We qualitatively explored care-seeking experiences of Japanese gynecological cancer survivors and deduced factors influencing care-seeking behaviors and treatment access.

[Questions that radiography students have regarding X-ray photography: a qualitative study].

Objective: To improve lectures and training programs on X-ray photography, we aimed to determine the questions that radiography students have regarding X-ray photography.

Methods: We collected text data from questions on X-ray photography in radiography student reports after an X-ray photography training program. The text data were analyzed using content analysis.

Filmless versus film-based systems in radiographic examination costs: an activity-based costing method.

Background: Since the shift from a radiographic film-based system to that of a filmless system, the change in radiographic examination costs and costs structure have been undetermined. The activity-based costing (ABC) method measures the cost and performance of activities, resources, and cost objects. The purpose of this study is to identify the cost structure of a radiographic examination comparing a filmless system to that of a film-based system using the ABC method.

Willingness to pay for municipality hospital services in rural Japan: a contingent valuation study.

Background: The Japanese healthcare system has undergone reforms to address the struggles that municipality hospitals face. Reform guidelines clearly define criteria for administrative improvement. However, criteria to evaluate the demand for healthcare provisions in rural Japan, including the needs of rural residents for municipality hospitals in particular have not been specified.

[Hierarchy structuring for mammography technique by interpretive structural modeling method].

Participation in screening mammography is currently desired in Japan because of the increase in breast cancer morbidity. However, the pain and discomfort of mammography is recognized as a significant deterrent for women considering this examination. Thus quick procedures, sufficient experience, and advanced skills are required for radiologic technologists.

[Developing and evaluating an auto-retrieval algorithm for abbreviations in academic articles].

The purpose of this study was to develop an automated acquisition support for the semantics of abbreviations and evaluate its performance with respect to academic articles. Our goal was to support the maintenance of an institution-specific semantics inventory for abbreviations on a continuous basis. We retrieved articles from MEDLINE with the keyword "Liver [MeSH]," and 100 abstracts were randomly selected.

Model analysis for optimal allocation of pediatric emergency center.

Optimal allocation of Pediatric Emergency Centers was simulated using both Min-Sum model and Min-Max model, based on the travel distance and child population of Hokkaido prefecture, Japan. Our result should be helpful to select the optimal number and allocation of PECs in the actual scene of decision making, where the financial restriction exists.

Semantic distribution study of noun*noun compounds in the Japanese CT clinical reports.

The purpose of this study is to investigate the distribution of the semantic relationships between the two atomic medical terms of the noun-noun compounds extracted from the clinical documents in Japanese. Only 29.9% of the compounds had the UMLS semantic relation defined (mainly including "location_of" and "adjacent_to").

[Development of a radioactive pharmaceuticals management system using a Web-based system].

Systems for recording data on radiopharmaceuticals have changed following the Medical Care Law on concentration limits of radioisotopes in drainage, exhaust gas, and the atmosphere. A Web-based system that includes a patient information subsystem, DICOM imaging subsystem, and laboratory order subsystem has been developed for the receipt, use, stock prescription, disposal, and accounting of radiopharmaceuticals was developed using a Web-based system in order to simplify radiation safety management operations such as changes and additions to record book forms. In verifying the usefulness of the system and its recording and search times, it was found that the new Web-based system provides superior performance.
