A concept of radiation beam matching of some medical linear accelerators (LINACs) that have identical characteristics of the models, radiation quality, and multileaf collimator features may be implemented as long as the manufacturer provides complete specifications so that a Treatment Planning System (TPS) can be used for many beam-matched LINACs....

A new development of a linear accelerator machine has been installed in Indonesia for the first time. There is no dosimetric protocol specifically discussing the measurement of absorbed dose to water in the Halcyon linac. But, few global dosimetric protocols determine the measurement of absorbed dose for linac machine which at the same substance. T...

p> The value of H_p(10) can be measured directly using H_p(10) secondary standard chamber that developed by Physikalisch Technische Bundensalt (PTB), Germany. H_p(10) secondary standard chamber type T 34035/0046 is connected with electrometer PTW Unidos T 10001 / Ns.11814. In this paper, the exposure was carried out by...

Salah satu alternatif untuk melakukan kalibrasi detektor ionisasi kecil pada lapangan radiasi kecil adalah dengan melakukan pengukuran daisy chaining. Makalah ini menguraikan pengukuran daisy chaining detektor ionisasi kecil pada berkas foton 6 MV flattening filter free lapangan radiasi kecil. Langkah pertama pengukuran daisy chaining adalah melaku...
