A modification of flattening filter free linac for IMRT
Tsiamas, P.; Seco, J.; Han, Z.; Bhagwat, M.; Maddox, J.; Kappas, C.; Theodorou, K.; Makrigiorgos, M.; Marcus, K.; Zygmanski, P. (2011)Purpose: This study investigates the benefits of a modified flattening filter free (FFF) linac over the standard (STD) linac equipped with the flattening filter. Energy and angular spread of the electron beam of the FFF ... -
A multipurpose quality assurance phantom for the small animal radiation research platform (SARRP)
Ngwa, W.; Tsiamas, P.; Zygmanski, P.; Makrigiorgos, G. M.; Berbeco, R. I. (2012)In this work, the suitability and performance of a mouse-size MOSFET (Mousefet) phantom is investigated for routine quality assurance (QA) of the small animal radiation research platform (SARRP). This Mousefet phantom is ... -
