In clinical X - ray and CT examinations, increasing radiation dose is often used to obtain high - resolution images of lesions. However, exposure to ionizing radiation, even at the minimum dose, may pose risks of cancer or leukemia. PMI foam has a low aluminum equivalent, which can increase X - ray transmittance. That is, it can obtain clearer images with a smaller radiation dose, helping to reduce radiation exposure during the examination.

Besides protecting patients from radiation, compared with traditional medical bed board materials, the carbon fiber PMI foam sandwich structure bed board is lightweight yet strong. It can increase the load - bearing capacity of the bed board. High - performance PMI foam not only reduces X - ray interference through its uniform pore size and surface resin distribution but also effectively reduces the thickness of the foam core, making the equipment more convenient to operate. Moreover, its easy machinability benefits the design of equipment. Using the carbon fiber PMI foam sandwich structure medical bed board can bring good benefits to patients, medical workers, and bed board manufacturers.
