We examine 2 strategies for reducing respiration-induced organ motion in radiation
treatment: deep inspiration breath hold (DIBH) and respiratory gating. DIBH is a controlled …

Intensity-modulated radiation therapy (IMRT) in head and neck (H&N) cancer has the
capability to generate steep dose gradients, leading to an improved therapeutic index. IMRT …

Purpose: Geometric uncertainties in the process of radiation planning and delivery constrain
dose escalation and induce normal tissue complications. An imaging system has been …

From background physics and biological models to the latest imaging and treatment
modalities, the Handbook of Radiotherapy Physics: Theory and Practice covers all …

Radiographic image guidance has emerged as the new paradigm for patient positioning,
target localization, and external beam alignment in radiotherapy. Although widely varied in …

Clinical conformal radiotherapy is the holy grail of radiation treatment and is now becoming
a reality through the combined efforts of physical scientists and engineers, who have …
