“…The typical maximum uncertainties/setup errors involved in left breast and chest wall treatment in the A/P direction (vertical chest wall excursion over the treatment duration) have been reported to be as large as 5 mm 13 , 14 , 15 . Patient‐induced chest wall shifts of a similar magnitude during DIBH have also been reported 7 , 8 …”

“…Existing studies suggest that setup errors in the A/P direction can range from approximately 2 to 5 mm 14 , 15 . Additional studies have shown that patients may shift their chest wall position during free breathing (FB), BH, and DIBH by 2.5 2.7 and 4.6 mm, respectively 7 , 8 , 14 , 15 . Similarly, uncertainty in the superior/inferior (S/I) direction may also be significant during DIBH delivery, where patient‐induced shifts may be as large as 6.6 mm (7) .…”

“…The dose delivered by these techniques may be affected by respiratory motion of the thorax during treatment 8 , 9 . These movements may be accounted for using breathing adapted radiotherapy (BART) techniques such as respiratory gating, breath‐hold (BH), and deep‐inspiration breath‐hold (DIBH) 5 , 7 , 8 , 9 , 10 .…”

DIBH is a technique used in the treatment of left‐sided breast cancer that allows for cardiac sparing (i.e., increasing the distance between the chest wall target and heart).…”

Chest wall radiation therapy treatment delivery was monitored using a 5 mm thick radiochromic poly(vinyl alcohol) cryogel that also provided buildup material. The cryogels were used to detect positioning errors and measure the impact of shifts for a chest wall treatment that was delivered to a RANDO phantom. The phantom was shifted by ±2,±3, and ±5 mm from the planned position in the anterior/posterior (A/P) direction; these shifts represent setup errors and the uncertainty associated with lung filling during breath‐hold. The two‐dimensional absolute dose distributions measured in the cryogel at the planned position were compared with the distributions at all shifts from this position using gamma analysis (3%/3 mm, 10% threshold). For shifts of ±2,±3, and ±5 mm the passing rates ranged from 94.3% to 95.6%, 74.0% to 78.8%, and 17.5% to 22.5%, respectively. These results are consistent with the same gamma analysis performed on dose planes calculated in the middle of the cryogel and on the phantom surface using our treatment planning system, which ranged from 94.3% to 95.0%, 76.8% to 77.9%, and 23.5% to 24.3%, respectively. The Pinnacle dose planes were then scaled empirically and compared to the cryogel measurements. Using the same gamma metric, the pass rates ranged from 97.0% to 98.4%. The results of this study suggest that cryogels may be used as both a buildup material and to evaluate errors in chest wall treatment positioning during deep‐inspiration breath‐hold delivery. The cryogels are sensitive to A/P chest wall shifts of less than 3 mm, which potentially allows for the detection of clinically relevant errors.PACS number(s): 87.55.km, 87.57.uq

“…Deep inspiration breath‐hold (DIBH) during radiotherapy is a well‐established technique for treating left‐sided breast cancer (LSBC), and provides a reliable solution to lessen cardiopulmonary doses in breast irradiation 1, 2. It is also assumed that the long‐term risk of developing cardiac damage is reduced 3, 4…”

Deep inspiration breath‐hold (DIBH) is a technique for treating left‐sided breast cancer (LSBC). In modern radiotherapy, one of the main aims is to exclude the heart from the beam aperture with an individualized beam design for LSBC. A deep inhalation will raise the chest wall while the volume of the lungs increase, this will again push the heart away from the breast to be treated. There are a few commercial DIBH systems, both invasive and noninvasive. We present an alternative noninvasive DIBH system based upon an industrial laser distance measurer. This system can be installed in a treatment room at a low cost; it is very easy to use and requires limited amount of training for the personnel and the patient. The system is capable of measuring the position of the chest wall with high frequency and precision in real time. The patient views its breathing curve through video glasses, and gets instructions during the treatment session. The system is well tolerated by test subjects due to its noninvasiveness.
