In vivo dosimetry for IMRT

In vivo dosimetry has a well established role in the quality assurance of 2D radiotherapy and 3D conformal radiotherapy. The role of in vivo dosimetry for IMRT is not as well established. IMRT introduces a range of technical issues that complicate in vivo dosimetry. The first decade or so of IMRT implementation has largely relied upon pre-treatment phantom based dose verification. During that

Radiation dosimetry

Radiation dosimetry refers to the measurement, calculation and assessment of the ionising radiation dose absorbed by the human body. Accurate dosimetry in radiotherapy is essential to eradicate a cancer, whilst minimising the risk of severe side effects due to the unavoidable irradiation of healthy tissues and organs.
