Patient Positioning Masks segmentation by type reflects distinct engineering approaches that drive market dynamics. Rigid masks, typically fabricated from thermoplastic polymers, offer high‑precision reproducibility and are favored in high‑precision radiotherapy, accounting for roughly 40 % of total unit sales. Semi‑rigid masks combine a polymer shell with a cushioning liner, balancing stability with patient comfort; they capture about 30 % of the market, particularly in head‑and‑neck protocols where moderate immobilization suffices. Flexible masks, constructed from silicone or elastomeric fabrics, prioritize comfort for longer procedures and are prevalent in neurosurgical and dental settings, representing close to 20 % of revenue. Custom‑molded masks, produced via 3‑D scanning and additive manufacturing, deliver patient‑specific geometry, supporting emerging adaptive‑therapy workflows; they currently hold an estimated 10 % share but exhibit the fastest CAGR due to expanding personalized‑medicine adoption. Collectively, these sub‑categories define the market taxonomy and illustrate how material performance, workflow integration, and clinical demand allocate the overall Patient Positioning Masks market size.
