Respiratory traces predicted treatment-day heart dose drift during post-mastectomy DIBH VMAT
Routine DIBH respiratory traces predicted fraction-level mean heart dose deviation, but LAD dose estimates were substantially less reliable.

Four quality-improvement measures reduced >3-mm chest-wall errors from 21.2% to 4.7%, but sternal marker placement increased skin reactions.
Across 52 studies, SGRT-assisted DIBH reduced mean heart dose by 1.21 Gy and LAD dose by 7.05 Gy versus free breathing.
Dynamic tangential IMRT delivered left-breast DIBH 42% faster than VMAT with similar target coverage and lower low-dose normal-tissue exposure.
Despite successful simulation, 31.7% required DIBH gate modification or conversion to free breathing during abdominal radiotherapy.
Thermo-optical surface monitoring with X-ray correction kept breast deep inspiration breath-hold setup errors within clinical tolerance.
