The exposure to ionizing radiation, even in minimal doses, is associated with the risk of developing cancer or leukemia. Patient tables for X-ray and CT scans with a structural core made of ROHACELL® help reduce the necessary radiation exposure in diagnostic procedures.
Because of its high material strength, only a relatively thin core of ROHACELL® with low density is required for X-ray and CT patient tables, which must meet the highest requirements. To meet the same mechanical demands, e.g., shear strength other foams have to be much thicker, or must have a higher density (view graph below). This not only affects how well the tables can be handled by the operator, but also leads to higher absorption rates of X-ray beams, which ultimately are either not available for diagnostic imaging or have to be improved by higher dosages affecting the patient's physical integrity.
