Secondary radiation emission induced by nuclear reactions is correlated to the path of ions
in matter. Therefore, such penetrating radiation can be used for in vivo control of …

Protons are an interesting modality for radiotherapy because of their well defined range and
favourable depth dose characteristics. On the other hand, these same characteristics lead to …

Radiation therapy treatments are typically planned based on a single image set, assuming
that the patient's anatomy and its position relative to the delivery system remains constant …

High-energy beams of charged nuclear particles (protons and heavier ions) offer significant
advantages for the treatment of deep-seated local tumors in comparison to conventional …

In vivo dosimetry (IVD) is in use in external beam radiotherapy (EBRT) to detect major errors,
to assess clinically relevant differences between planned and delivered dose, to record …

Charged particle beam radiotherapy requires dedicated measures to compensate for the
dosimetric influence of inter-and intra-fractional target motion. Independent of the delivery …

Hadron therapy allows for highly conformal dose distributions and better sparing of organs-
at-risk, thanks to the characteristic dose deposition as function of depth. However, the quality …

Proton and ion beams open up new vistas for the curative treatment of tumors, but adequate
technologies for monitoring the compliance of dose delivery with treatment plans in real time …

Purpose: To investigate the feasibility and value of positron emission tomography and
computed tomography (PET/CT) for treatment verification after proton radiotherapy. Methods …

In this review paper, we first give a short overview of radiological image guidance in photon
radiotherapy, placing emphasis on the fact that linac based radiotherapy has outpaced …
