多模式医学图像融合体位固定通用床板

Design of Universal Bed Board by Immobilizing for Multi-mode Medical Images Fusion

目的:设计一种能固定受检者体位、与受检者一同搬动、适用于多种影像检查的通用床板。方法:床板呈"簸箕"槽状,采用低密度塑料注塑而成,其内置有规则走形、充满多功能显影剂的管线,床板上面设有负压真空气垫和固定人体的系带。图像融合时,先进行单模式的图像容积重建,再依据冠状和矢状显影标志管线进行配准容积融合。结果:床板在软组织窗下CT、MRI、PET、SPECT均不显影。受检者在多种影像检查的体位一致。图像融合配准标志的显影管线明显,已申报国家专利。结论:利用通用床板进行多模式图像融合,快捷迅速,简单准确,可行有效,易于推广普及。

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 ＂muhifunction 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 multimode 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.
