ROHACELL® helps reduce radiation exposure

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.

The homogenous cell structure of ROHACELL^® and the resulting even surface distribution of resin leads to low-interference X-ray images for optimal diagnosis. As an additional benefit, the structural foam is easy to process mechanically and can be shaped with thermoforming methods.

Whether used in X-ray tables, CT beds or mammography plates for diagnostic purposes, stretchers and OR tables in emergency medicine, or in specialty tables and attachments for therapeutic use, ROHACELL^® is a structural core that benefits patients, hospital staff, and manufacturers alike, thanks to the outstanding properties of this unusual structural foam.
