Tomoscan AV型CT图像采集的设计与实现

目的：解决非DICOM接口的CT设备的图像一直以胶片的形式储存，不能实现永久数字化存储、共享、检索、图文报告等问题。方法：介绍了图像数字化采集的一种方法，重点阐述了图像采集与切割技术。硬件由CT机、PC机、OK_RGB20B图像采集卡、脚踏开关组成，软件由VC＋＋6．0、OK_RGB20B开发包及GDI＋类库编程实现。结果：系统顺利实现了CT图像的数字化采集，使图像得到了永久的存储与共享。结论：对于各类非DICOM接口医学影像设备（ECT、X线机、超声仪、内窥镜等）的图像的数字化采集具有参考价值。

Design and realization of image acquisition system for Philip Tomoscan AV CT

Objective The images of CT Equipment without DICOM interface are stored by means of film all along,and they can't be digitally stored,shared,retrieved,integrated to diagnostic reports.This paper introduces a method to capture images,mainly focus on the image capture and crop technology.Methods The hardware is composed of Philip Tomoscan AV CT,PC,OK_RGB20B image capture card,foot switch.The software is programmed by Microsoft Visual C++6.0,OK_RGB20B SDK and GDI+ Class Library on Windows 2000 operating system.Results The system can capture the CT image successfully,and make the images stored and shared permanently.Conclusion This method is a valuable clew for capturing images from other types of non-DICOM-based medical equipment such as ECT,X-ray,Ultrasound,Endoscope and so on.
