![]() Seabirds comprised the greatest number of records, compared to the other two taxa, and most records were from shipboard surveys, compared to the other three platforms. All datasets published on OBIS-SEAMAP up to February 2009 were summarized spatially and temporally. As data accumulated, spatial and temporal biases resulted and a comprehensive gap analysis was needed in order to assess coverage to direct data acquisition for the OBIS-SEAMAP project and for taxa researchers should true gaps in knowledge exist. Spatio-temporal gap analysis of OBIS-SEAMAP project data: assessment and way forward.ĭirectory of Open Access Journals (Sweden)įull Text Available The OBIS-SEAMAP project has acquired and served high-quality marine mammal, seabird, and sea turtle data to the public since its inception in 2002. The project not only improves the utilization rates of radiotherapy software, but also makes it possible that the cloud computing technology can expand its applications to the field of radiation oncology. The cloud platform transplantation in this study is economical and practical. The function test results of the cloud workstation show that a cloud workstation is equivalent to an isolated physical workstation, and any clients on the LAN can use the cloud workstation smoothly. Finally the software on the cloud was able to be accessed by virtual desktop client. Then on the private cloud platform, all the Varian radiotherapy software modules were installed to the virtual machine, and the corresponding function configuration was completed. First, a private cloud platform which was based on OpenStack and the virtual GPU hardware was builded. To develop a low-cost private cloud platform of radiotherapy software.

It focuses on localizing tumors based on internal anatomy, not just on the conventional external marks or tattoos. The CBCT function of OBI was installed in March 2005 at our department. For this purpose, on-board kV-kV seems to be an ideal system in terms of image quality. Displacements of these markers can be monitored radiographically during the treatment course and the registered marker shifts act as a surrogate for prostate motion. The OBI has been used for on-line set-up correction of prostate patients using internal gold markers. In this paper we present the on-board imager ( OBI, Varian Medical Systems, Palo Alto, CA) that has been in routine clinical use at the Karolinska University Hospital since June 2004. ![]() The verification of the accurate treatment position in conjunction with detailed anatomical information before every fraction can be essential for the outcome of the treatment. ![]() Some of the most recent available methods applied for target localization are: trans-abdominal ultrasound, implanted markers with in room MV or kV X-rays, optical surface tracking systems, implantable electromagnetic markers, in room CT such as kVCT on rail, kilo-voltage or mega-voltage cone-beam CT (CBCT) and helical megavoltage CT. Image-guided radiation therapy (IGRT) can be used to measure and correct positional errors for target and critical structures immediately prior to or during treatment delivery.
