在这份报告中,我们介绍了基本架构和光学处理技术在医学成像中的潜在应用。三个基本的光学处理架构进行了研究,用于数字和模拟射线照相。处理器包括一个将模拟或数字射线照片转换为相干光分布的模块;一个执行各种数学运算的相干光学处理架构;一个可编程数字光学接口和其他附件。实施光学频率滤波器用于乳房X线摄影和其他临床特征增强。在医学图像处理中,数字计算机提供了可编程性和灵活性的优势。相反,光学处理器以高速执行并行图像处理。光学处理器还提供模拟特性、紧凑尺寸和成本效益。随着数字光学接口设备的技术进步,在可预见的未来,医学图像处理器可能是混合设备,即可编程光学架构。
In this report we introduce the fundamental architectures and the potential applications of optical processing techniques in medical imaging. Three basic optical processing architectures were investigated for digital and analog radiography. The processors consist of a module that converts either the analog or the digital radiograph into a coherent light distribution; a coherent optical processing architecture that performs various mathematical operations; a programmable digital–optical interface and other accessories. Optical frequency filters were implemented for mammographic and other clinical feature enhancement. In medical image processing, digital computers offer the advantages of programmability and flexibility. In contrast, optical processors perform parallel image processing with high speed. Optical processors also offer analog nature, compact size, and cost effectiveness. With technical advances of digital–optical interface devices, the medical image processor, in the foreseeable future, may be a hybrid device, namely, a programmable optical architecture.
