Design of Universal Bed Board by Immobilizing for Multi-mode Medical Images Fusion / 医疗卫生装备

ABSTRACT

Objective To design a kind of bed board that is suitable for various medical image diagnostic equipments. It is used to make the body position of the person who is examined to be fixed and can be moved with whom. Methods The bed board is made of low density plastics; its structure is similar to "winnowing fan" in shape. In which, the pipes filled with "multifunction developer" are arranged in order. The negative pressure vacuum bag and belts for the body positioning are installed on the bed board. Volumetric reconstruction has been done with single mode images, then multi- mode images volumetric fusion depend on registration with coronal and arrowy mark of image pipeline in volumetric reconstruction. Results The bed board can not be showed in CT, MRI, PET and SPECT with the soft tissue window, but the pipes be used as the marker for image fusion is displayed clearly. The body position is all the same with each medical image examination. National patent of the product was declared. Conclusion With the designed bed board, the multimode image fusion is rapid, simple and accurate, is easily expansion and popularize.
