![]() The measured values were comparable for patients undergoing RT in vDIBH, and for those in FB. The mean difference between the distance from the CA to ICW on DRR and the equivalent distance on CINE imaging (as treated) was 0.28Â cm (SD 0.17) for vDIBH patients and 0.25Â cm (SD 0.14) for FB patients (PÂ =Â 0.458). The maximum intra-beam motion for any one patient measurement was 0.30Â cm for vDIBH and 0.20Â cm for FB. These were then compared to the planned distance on digitally reconstructed radiograph (DRR). The intra-beam motion was assessed and the distance from the beam central axis (CA) to the internal chest wall (ICW) was measured on each CINE image. Weekly CINE images were retrospectively assessed for 20 left-sided breast cancer patients receiving RT in vDIBH, and compared with CINE images of 20 patients treated in FB. The electronic portal imaging device (EPID) was used in cinematographic (CINE) mode to capture a sequence of images during beam delivery. An in-house quality assessment of positional reproducibility during RT delivery with vDIBH in patients with left-sided breast cancer was evaluated. Recently, a voluntary deep inspiration breath-hold (vDIBH) technique was established using in-room lasers and skin tattoos to monitor breath-hold. ![]() To evaluate the impact of moderate deep inspiration breath hold (mDIBH) using an active breathing control (ABC) apparatus on heart, spinal cord, liver and contra lateral lung doses and its volumes compared with free breathing (FB) with lung cancer irradiationĪssessment of voluntary deep inspiration breath-hold with CINE imaging for breast radiotherapy.Įstoesta, Reuben Patrick Attwood, Lani Naehrig, Diana Claridge-Mackonis, Elizabeth Odgers, David Martin, Darren Pham, Melissa Toohey, Joanne Carroll, Susanĭeep Inspiration Breath-Hold (DIBH) techniques for breast cancer radiation therapy (RT) have reduced cardiac dose compared to Free Breathing (FB).
