Author: Makan Farrokhkish, et al, Multi-Center Study Summary: This multi-center study investigated the IQM System for constancy measurements of various beam parameters for photon beams. The results suggest that the system can be used for most of the routine QA tests effectively and efficiently. .
Author: K.L. Yun, et al, Allegheny Health Network (USA) Summary: The clinical physics group compared the sensitivity of the IQM System to beam energy changes against 4 other conventional methods. They concluded that the IQM device was approximately twice as sensitive as the other chamber methods. .
Author: Y. Liang, et al, Allegheny Health Network (USA) Summary: The clinical physics group compared Sun Nuclear SRS MapCheck and IQM for the patient-specific QA of three single ISO multi-met SRS plans created with the Brainlab Elements MME TPS. They concluded that both systems showed good agreement between the QA results, but that the QA …
