Title: A data management system for radiological data

Abstract

A data management system oriented toward the visualization of large data sets has been developed. The system, which runs under the Windows{trademark} operating environment, provides most of the image-based algorithms developed by NASA for space-based imaging. When used in conjunction with large data sets, such as those acquired using position-sensing proportional counter based survey methods, the system can show images of survey data and subject those images to numerous mathematical transformations. The application of such mathematical treatments allows radiological survey data to be analyzed to an unprecedented extent. Visualization of survey data permits a user to see minor artifacts that would have been missed using only conventional survey techniques. The imaged survey data can be subjected to many different treatments, such as filters, smoothing, thresholding, color mapping, and statistical analyses. A variety of radioactive objects and areas have been surveyed using this system in conjunction with a novel floor monitor described elsewhere. Collection and examination of data in this fashion poses a new paradigm for assessing surface contamination. This research demonstrated that new methods for assessing survey performance are needed.

  • In this paper, a radiological data management system (RDMS) is developed that simplifies the compilation and retrieval of data relating to the occupational exposure of individuals to radiation. The system captures historical occupational dose record data, current and real time internal and external exposure data, and data pertaining to exposure to airborne contaminants. RDMS also develops reports required for ALARA analysis and permanent hard copy recordkeeping systems. The system is capable of being installed on, and interfaced with, most existing computer platforms or programs. The two main advantages of RDMS are that it reduces the time required to develop andmore » maintain occupational exposure and radiation work permit records and that the records generated by RDMS are consistent, complete, and up-to-date.« less
  • RIMS/sup tm/ has been developed for health physics record keeping and reporting. It provides for the management needs relating to radiological information control at a nuclear facility. The program is comprised of the following modules: Personnel Radiological Information, Radiological Work Permit, Radiation Survey Records, Access Control, ALARA Reporting, and Respirator and Survey Instrument Inventory Modules.

  • Purpose. The purpose of this study was to retrospectively evaluate interventional radiological management of patients with symptomatic portal hypertension secondary to obstruction of splanchnic veins. Material and Methods. Twenty-four patients, 15 males and 9 females, 0.75 to 79 years old (mean, 36.4 years), with symptomatic portal hypertension, secondary to splanchnic venous obstruction, were treated by percutaneous methods. Causes and extent of splanchnic venous obstruction and methods are summarized following a retrospective evaluation. Results. Obstructions were localized to the main portal vein (n = 22), intrahepatic portal veins (n = 8), splenic vein (n = 4), and/or mesenteric veins (n =more » 4). Interventional treatment of 22 (92%) patients included recanalization (n = 19), pharmacological thrombolysis (n = 1), and mechanical thrombectomy (n = 5). Partial embolization of the spleen was done in five patients, in two of them as the only possible treatment. TIPS placement was necessary in 10 patients, while an existing occluded TIPS was revised in two patients. Transhepatic embolization of varices was performed in one patient, and transfemoral embolization of splenorenal shunt was performed in another. Thirty-day mortality was 13.6% (n=3). During the follow-up, ranging between 2 days and 58 months, revision was necessary in five patients. An immediate improvement of presenting symptoms was achieved in 20 patients (83%). Conclusion. We conclude that interventional procedures can be successfully performed in the majority of patients with obstruction of splanchnic veins, with subsequent improvement of symptoms. Treatment should be customized according to the site and nature of obstruction.« less
  • The eFRMAC enterprise is a suite of technologies and software developed by the United States Department of Energy, National Nuclear Security Administration‚Äôs Office of Emergency Response to coordinate the rapid data collection, management, and analysis required during a radiological emergency. This enables the Federal Radiological Monitoring and Assessment Center assets to evaluate a radiological or nuclear incident efficiently to facilitate protective actions to protect public health and the environment. This document identifies and describes eFRMAC methods including (1) data acquisition, (2) data management, (3) data analysis, (4) product creation, (5) quality control, and (6) dissemination.
