Rotation Effects on the Target-Volume Margin Determination [PDF]

open access: yesPhysica Medica (2014), 2014
Rotational setup errors are usually neglected in most clinical centers. An analytical formula is developed to determine the extra margin between clinical target volume (CTV) and planning target volume (PTV) to account for setup errors. The proposed formula corrects for both translational and rotational setup errors and then incorporated into margin ...

Preliminary results in using Deep Learning to emulate BLOB, a nuclear interaction model [PDF]

open access: yesPhysica Medica Volume 73, May 2020, Pages 65-72, 2020
Purpose: A reliable model to simulate nuclear interactions is fundamental for Ion-therapy. We already showed how BLOB ("Boltzmann-Langevin One Body"), a model developed to simulate heavy ion interactions up to few hundreds of MeV/u, could simulate also $^{12}$C reactions in the same energy domain.
