Purpose High energetic carbon (C-) ion beams undergo nuclear interactions with tissue, producing secondary nuclear fragments. Thus, at depth, C-ion beams are composed of a mixture of different particles with different linear energy transfer (LET) val

Purpose: Magnetic resonance imaging–guided radiotherapy (MRIgRT) provides superior soft-tissue contrast and real-time imaging compared with standard image-guided RT, which uses x-ray based imaging. Several groups are developing integrated MRIgRT ma

Purpose: The use of radiotherapy fields smaller than 3 cm in diameter has resulted in the need for accurate detector correction factors for small field dosimetry. However, published factors do not always agree and errors introduced by biased referenc

Twenty-one mixed-parity (average 2.4 ± 0.49) crossbred sows and their offspring were used to determine whether sow milk leptin at farrowing was re- lated to neonatal serum leptin and pig growth to wean- ing. During farrowing, pigs were randomly allo
