RGSC System Commissioning for Philips CT

Check if the same lab product or an alternative is used in the 5 most similar protocols
A recently installed RGSC system (SN 1825; Varian Medical Systems, Palo Alto, CA, USA) was used for the test that was interfaced with a recently installed Philips Brilliance Big Bore 16 CT scanner (SN 50566500972; Philips Healthcare,Andover, MA, USA). A CARINAiso 3 green laser system (LAP Laser, Boynton, FL, USA) was used as the alignment reference. A dynamic 4D phantom, QUASAR (Modus Medical Devices, London, ON, Canada) was also used in the QA of the RGSC system. A set of 30 × 30 × 30-cm3 solid water (Gammex RMI; Sun Nuclear, Melbourne, FL, USA) slabs were used in certain tests as buildup material, and a regular ruler with millimeter resolution was also used. MATLAB (R2016a; The MathWorks, Natick, MA, USA) code was programmed to read in and compare the breathing curves recorded by the RGSC and RPM (version 1.6; Varian Medical Systems) systems. The breathing curves recorded from an RPM system were used for patient-specific breathing pattern tests and comparison. Up to now, the RGSC system was only benchmarked with a Philips CT scanner in the USA (personal communication with Varian Medical Systems representative); therefore, we only focused on its acceptance and commissioning for the Philips Brilliance Big Bore CT scanner in the present study. However, the procedures used should be easily adapted to other types of CT scanners.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
