Breast and lung positioning accessory family — Wing-Board T-Grip for above-head arm clearance, variable-angle supine breast board, prone breast board with breast cut-out, matching supine + prone breast cushions and prone belly cushion. Indexed onto the thorax baseplate for tangential breast IMRT, DIBH heart-sparing workflows, prone-breast setup (large breast or lung-sparing indication) and lung tangential treatment. Radiolucent composite construction; < 2 % beam attenuation. Wipe-down decontaminable surfaces.

Five worked breast + lung workflows the six-piece accessory family covers
Supine breast board + supine breast cushion + wing-board T-grip. Variable board angle locks the chest-wall angle for tangential fields; T-grip clears the lateral beam path; DIBH gating delivers the heart-dose sparing benefit. Per-fraction reproducibility within < 3 mm at the chest wall.
Same chain as left-breast minus the DIBH gating requirement. Right-side tangential setup; reproducibility expectation per AAPM TG-66.
Prone breast board + prone breast cushion + prone belly cushion. Breast hangs free in the cut-out; lung is displaced anteriorly; setup reduces ipsilateral lung dose by 30–50 % vs supine for larger breast volumes.
Thorax baseplate + supine breast cushion (posture support) + wing-board T-grip. Same chain as breast tangential; useful for tangential lung fields where the arm position dominates beam-path clearance.
Thorax + pelvis baseplate chain with the supine breast board + prone belly cushion engaging on different fraction days. Single accessory pack covers both posture modes — supine for breast, prone for nodal pelvic.
Per-batch material certificate + attenuation report + per-patient breast-board angle record. The AERB / facility QA programme reads the chain at routine inspection.
Some patients are better treated supine (smaller breast, standard chest-wall geometry); some benefit from prone (larger breast, lung-sparing indication). The accessory family covers both — supine breast board + cushion AND prone breast board + cushion — so the department picks per-patient without a separate procurement cycle.
Wing-Board T-grip clears the arms for the lateral tangent beam paths; the breast cushion holds the patient at the indexed posture even during the 15–25 second breath-hold. DIBH-driven heart-dose reduction (typically 30–50 % heart-mean-dose reduction for left-breast) is reproducible only when the posture chain locks every fraction.
Indexed mounting to the thorax baseplate at the standard couch-bar pitch. The CT-sim setup, the MR-sim setup (where used) and the linac setup all read the same indexing. The breast-board assembly does not need per-room recalibration; the patient setup transfers room-to-room at the indexing precision of the baseplate.
Variant matrix
Six components covering supine and prone breast workflows, lung tangential and combined breast-pelvic setups. The use-case build sheet matches components to the per-patient breast-radiotherapy decision; the Accessories Matrix below covers the indexing and material details.
Six-component accessory family
Wing-Board T-Grip
Above-head dual-arm grip — clears both arms out of the chest / breast treatment field; DIBH-compatible ergonomics; pairs with the thorax baseplate
Supine Breast Board
Variable-angle inclined board for supine tangential breast treatment; angle indexed for reproducible setup across the fraction series
Prone Breast Board
Prone breast treatment board with breast cut-out — left- or right-side breast hangs free from the chest wall to reduce skin dose and lung exposure
Supine Breast Cushion
Conformal cushion under the supine breast board — supports the patient at the indexed angle without slip; improves comfort + reproducibility
Prone Breast Cushion
Conformal cushion under the prone breast board — supports the chest, abdomen and pelvis at the prone angle; reduces inter-fraction posture drift
Prone Belly Cushion
Belly-board cushion for prone pelvic or breast-pelvis combined workflows — displaces small bowel out of the high-dose region
Use-case build sheet
| Workflow | Configuration | Why |
|---|---|---|
| Left-breast tangential + DIBH | Thorax baseplate + supine breast board (variable angle) + supine breast cushion + wing-board T-grip | Heart-dose-sparing benefit from DIBH is reproducible only when the breast-board angle and arm position lock identically every fraction. Indexed angle + T-grip + cushion combination satisfies the AAPM TG-263 / TG-66 setup-reproducibility expectation. |
| Right-breast tangential | Thorax baseplate + supine breast board + supine breast cushion + wing-board T-grip | Right-side tangential setup; same chain as left-breast but no DIBH benefit. Board angle indexing still matters for reproducible setup across the 15–25 fraction series. |
| Prone-breast (large breast) | Thorax baseplate + prone breast board + prone breast cushion + prone belly cushion | Larger breasts hang free in the prone board cut-out — reduces lung dose and skin dose vs supine. Especially relevant for breast targets with axillary involvement or where supine breast positioning crosses the contralateral breast. |
| Lung tangential | Thorax baseplate + wing-board T-grip + supine breast cushion (for posture support) | Lung tangential and 3D-CRT workflows benefit from the same above-head arm clearance and posture support as breast tangential. The T-grip + cushion combination clears the lateral and oblique beam paths. |
| Combined breast-pelvic | Thorax + pelvis baseplate chain + supine breast board + prone belly cushion (for nodal pelvic fields) | Combined breast + nodal-pelvic workflows where the supine breast board and the prone belly cushion engage on different fraction days. Single accessory pack covers both posture modes. |
Accessories Matrix
| Angle-indexed lock on supine breast board | Reproducible board angle across the fraction series; per-patient angle recorded once at simulation, reproduced on every linac session |
| Cut-out shape on prone breast board | Allows left- or right-side breast to hang free below the board — reduces skin dose and lung exposure vs supine setup |
| Belly-board cut-out on prone belly cushion | Displaces small bowel away from the pelvic high-dose region; reduces small-bowel dose by ≈ 10–15 % vs supine for rectum and prostate-bed workflows |
| Wing-board T-grip dual-arm hold | Symmetric above-head arm position; DIBH-compatible ergonomics; clears lateral beam paths |
| Indexed mounting to thorax / pelvis baseplate | Pairs with the patient-positioning baseplate platform via the indexed couch-bar pitch — no per-room recalibration of the breast-board assembly |
| Radiolucent composite construction | Typical < 2 % beam attenuation at MV photon energies; the breast and lung treatment beam paths see negligible perturbation |
| Wipe-down decontaminable surfaces | All boards and cushions are wipe-down compatible with standard radiotherapy decontaminants; reusable across patients |
| Patient comfort liner (single-use) | Disposable hypoallergenic liner option improves patient comfort during the often-lengthy breast-treatment fraction; does not affect setup reproducibility |
