Tomoscan AV型CT图像采集的设计与实现

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

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。

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.
