It uses a high-strength polyurethane multi-layer composite film (antibacterial, anti-contamination, soft,comfortable). Filled with polymer foam particles inside, it fits body curves more precisely, being light-weight and conformable. Vacuum-pressed to shape the flexible filling, it offers precise shaping, stablefixation and uniform pressure distribution. Primarily for precise body positioning in radiotherapy, it alsoapplies to surgery, imaging exams and rehabilitation care, with good stability and almost no radiationattenuation.
