Title: Development and Use of a GIS Workstation at the Oak Ridge National Laboratory

Abstract

Oak Ridge National Laboratory (ORNL) is the Department of Energy s (DOE) largest multipurpose science and energy laboratory. As an interdisciplinary research organization, access to information plays a critical part in the success of the many research efforts in progress at the Laboratory. The Research Library, in a supportive role, enables staff to fulfill the Laboratory s mission by making available a myriad of information resources including paper and electronic maps. The Research Library Geographic Information System (GIS) workstation was developed to better serve library customers by providing convenient access to a variety of mapping resources. The GIS workstation functions as a supplement to the paper map collection by providing customers with maps in an electronic format that can easily be inserted into memos, reports, and journal articles. Customer interest, together with the growing availability of low-cost and user-friendly mapping software, led to the development of the GIS workstation, which hosts an array of commercial mapping software that enables customers to produce ready-made topographic maps, current and historical maps, and road maps. Customers may also create customized maps using their own data or data supplied by the software vendor. This article focuses on the development, implementation, and use of themore » library s GIS workstation by providing a brief description of hardware components, mapping resources, and how these resources are used by Laboratory staff.« less

  • This work describes the installation, use, and quality control (QC) of the alumina-based tungsten-188 ({sup 188}W)/rhenium-188 ({sup 188}Re) generators provided by the Oak Ridge National Laboratory (ORNL). In addition, methods used for concentration of the {sup 188}Re-perrhenate bolus and preparation of {sup 188}Re-labeled HDD (4-hexadecyl-2,2,9,9-tetramethyl-4,7-diaza-1,10-decanethiol) for trans-arterial administration for therapy of nonresectable liver cancer also are described. The {sup 188}W/{sup 188}Re generator has a long useful shelf-life of several months and is a convenient on-site {sup 188}Re production system. {sup 188}Re has excellent therapeutic and imaging properties (T{sub 1/2} 16.9 hours; E{sub {beta}max} 2.12 MeV; 155-keV gamma ray, 15%) andmore » is cost effectively obtained on demand by saline elution of the generator. The clinical efficacy of a variety of {sup 188}Re-labeled agents has been demonstrated for several therapeutic applications. Because of the favorable physical properties of {sup 188}Re, several {sup 188}Re-labeled agents are being developed and evaluated for the treatment of nonresectable/refractory liver cancer. {sup 188}Re-labeled HDD has been the most widely studied of these agents for this application and has been introduced into clinical trials at a number of institutions. The trans-arterial administration of {sup 188}Re-labeled agents for treatment of inoperable liver cancer requires use of high-level (1-2 Ci) {sup 188}W/{sup 188}Re generators. The handling of such high levels of {sup 188}Re imposes radiological precautions normally not encountered in a radiopharmacy and adequate care and ALARA (i.e., 'As Low As Reasonably Achievable') principles must be followed. The ORNL generator provides consistently high {sup 188}Re yields (>75%) and low {sup 188}W parent breakthrough (<10{sup -3}%) over an extended shelf-life of several months. However, the high elution volumes (20-40 mL for 1-2 Ci generators) can require concentration of the {sup 188}Re bolus by postelution passage through silver cation chloride trapping columns used in the cost-effective tandem cation/anion column system. The silver column removes the high levels of chloride anion as insoluble AgCl, thus allowing subsequent specific trapping of the perrhenate anion on the small (QMA SeaPak) anion column. This method permits subsequent elution of {sup 188}Re-perrhenate with a small volume of saline, providing a very high activity-concentration solution. Because the {sup 188}Re-specific volume-activity concentration continually decreases with time, the tandem system is especially effective method for extending the useful generator shelf-life. Low elution flow rates (<1 mL/min) minimize any high back pressure which may be encountered during generator/tandem column elution when using tightly packed, small-particle-size commercial columns. In-house preparation of silver cation columns is recommended since the chloride trapping capacity is essentially unlimited, it is inexpensive and not limited in availability to any one supplier, and back pressure can be eliminated by the use of larger particles. Methods for the preparation of {sup 188}Re-HDD have been optimized and this agent can be obtained in high yield (80%).« less
