“…The major movement is always along the cranio-caudal axis with a magnitude around 13 mm and a repositioning error of 1.2 mm. These results are consistent with the existing studies on the liver movement during shallow breathing [21][22][23][24]. Fig.…”

“…the preoperative CT and the computer guidance are realized at the same point of the breathing cycle (generally expiration). This reasonnable assumption is based on clinical studies performed on the organ repositioning error of a patient under breathing monitoring (intubation, ABC control or active apnea) evaluated below 2 mm [20][21][22][23][24]. However, it has to be highlighted that these experiments were performed in controlled conditions (volunteers were not to undergo a heavy intervention), and within a delay that may not fit clinical conditions.…”

“…9 Further innovations in treatment planning are therefore under investigation, including intensity modulation 10,11,12 and various techniques for the control of respiratory motion. 13,14,15,16,17,18,19,20,21 The aim of these techniques is to reduce still further the dose received by the heart, in the hopes of minimizing the long-term morbidity and mortality associated with the treatment of breast cancer.…”

Purpose-To reduce cardiotoxicity from breast radiotherapy (RT), innovative techniques are under investigation. Information about cardiac motion with respiration and positional reproducibility under active breathing control (ABC) is necessary to evaluate these techniques.Methods-Patients requiring loco-regional RT for breast cancer were CT-scanned using an ABC device at various breath-hold states, before and during treatment. Ten patients were studied. For each patient, 12 datasets were analyzed. Mutual information-based regional rigid alignment was used to determine the magnitude and reproducibility of cardiac motion as a function of breathing state. For each scan session, motion was quantified by evaluating the displacement of a point along the left anterior descending artery (LAD) with respect to its position at end expiration. Long-term positional reproducibility was also assessed.Results-Displacement of the LAD was greatest in the inferior direction, moderate in the anterior direction, and lowest in the left-right direction. At shallow breathing states, the average displacement of LAD position was up to 6mm in the inferior direction. The maximum displacement in any patient was 2.8cm in the inferior direction, between expiration and deep-inspiration breath hold (DIBH). At end expiration, the long-term reproducibility (SD) of the LAD position was 3mm in the A-P, 6mm in the S-I, and 4mm in the L-R directions. At DIBH, long-term reproducibility was 3mm in the A-P, 7mm in the S-I, and 3mm in the L-R directions.Conclusions-These data demonstrate the extent of LAD displacement that occurs with shallow breathing and with DIBH. This information may guide optimization studies considering the effects of respiratory motion and reproducibility of cardiac position on cardiac dose, both with and without ABC.

“…26,27 Although several techniques, like the use of active breath control devices (allowing a gated beam delivery) and Stereotactic body frame (with or without an abdominal compression plate), have attempted to negate liver motion or to reduce it. [28][29][30] The management of intrafraction variability in liver position remains aleatory.…”
