医学影像检查可以直观地看到病灶区域,但是却难以判定肿瘤的具体种类和恶化程度。活检是一种有创伤的检查手段,无疑会给病患带来更多的痛苦。磁共振波谱(MRS)是利用波谱的化学位移研究化合物组分和分子结构的一门科学,是医学影像学近年来发展起来的一种新的检查手段。作为一种无创伤研究活体器官组织代谢、生化变化及化合物定量分析方法,磁共振波谱能够反映正常和病理组织的代谢信息和状态,确定组织的性质,被称为“虚拟活检”。本文通过多次实验,不断对解析方案进行修正,最终解析出飞利浦磁共振波谱体素的空间位置信息。根据MR图像的空间位置信息和磁共振波谱体素的空间位置信息,利用可视化工具包VTK,实现了飞利浦磁共振波谱体素与磁共振图像的配准,方便医生精确地了解体素在大脑中的位置,准确地诊断脑肿瘤的类型和级别,为治疗方案的制定和治疗提供参考。
Medical imaging can visually see the lesion area, but it is difficult to determine the specific type of tumor and the degree of deterioration. Biopsy is a traumatic inspection that undoubtedly brings more pain to the patient. Magnetic Resonance Spectroscopy (MRS) is a science that makes use of chemical shifts of spectra to study the composition and molecular structure of compounds. It is a new examination method developed by medical imaging in recent years. As a noninvasive method to study metabolism, biochemical changes and quantitative analysis of living organ tissue, magnetic resonance spectroscopy can reflect the metabolic information and status of normal and pathological tissues and determine the properties of tissues, which is called “virtual biopsy.” In this paper, through many experiments, the analytical solution is constantly revised, and finally the spatial position information of the magnetic resonance spectroscopy voxels of Philips is finally resolved. According to the spatial location information of MR images and the spatial location information of magnetic resonance spectroscopy voxels, the visualization toolkit VTK is used to realize the registration of magnetic resonance spectroscopy (VIRS) and magnetic resonance images (MRIs) Of the location, accurately diagnose the type and level of brain tumors for the treatment of the formulation and treatment to provide a reference.
