Volume models made from magnetic resonance images on computed tomographs can produce horizontal, coronal, sagittal, and oblique planes that are used widely in clinics, although detailed structures cannot be identified. Existing real color volume models are mostly commercial and their production methods have not been released. The aim of this study was to distribute free of charge, real-color volume models produced from sectioned images with the production method.
The original voxel size of sectioned images was increased appropriately so that the volume model could be handled by typical personal computers. By using Dicom Browser and MRIcroGL, the sectioned images were processed to become the volume models.
On the MRIcroGL, the resultant volume model with the voxel size of 0.5 × 0.5 × 0.5 mm could be displayed and freely rotated. By adjusting variables of the software, desired oblique planes could be produced instantly. With overlay function, a model of segmented structure can be overlapped to the entire volume models. The sectioned images with high quality and the segmentation data of Visible Korean enabled the identification of detailed anatomical structures on the planes.
The volume models can be used by medical students and doctors for learning sectional anatomy. Other researchers can utilize the method of this study to produce volume models from their own sectioned images.
在计算机断层扫描的磁共振图像上制作的容积模型可以产生水平、冠状、矢状和斜平面,这些平面在临床中广泛应用,尽管无法识别详细结构。现有的真实彩色容积模型大多是商业性的,其制作方法尚未公布。本研究旨在免费分发用切片图像制作的真实彩色容积模型及其制作方法。
适当增加切片图像的原始体素大小,使典型的个人计算机能够处理容积模型。通过使用 Dicom Browser 和 MRIcroGL 处理切片图像,使其成为容积模型。
在 MRIcroGL 上,可以显示体素大小为 0.5×0.5×0.5mm 的容积模型,并可以自由旋转。通过调整软件的变量,可以立即生成所需的斜平面。通过叠加功能,可以将分割结构的模型叠加到整个容积模型上。高质量的切片图像和可见韩国的分割数据使得在这些平面上可以识别详细的解剖结构。
容积模型可供医学生和医生学习断面解剖学使用。其他研究人员可以利用本研究的方法,从自己的切片图像中生成容积模型。
