ABSTRACT
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.
ABSTRACT
This paper develops a type of x-ray unit which can produce x-ray image suitable for medical diagnosis. The unit is composed of a CCD image sensor with high sensitivity and high resolution, a digital image acquisition board, and a suit of computer software. The software can be applied as the doctor's workstation with the functions of patient register, image process and image management. Some styles of digital radiography technology are introduced briefly, and the principle of the x-ray unit as well as its hardware and software designs are presented particularly.
ABSTRACT
Objective To study the measuring method for amplitude of transducer's tip in ultrasonic surgical apparatus, and design a set of practical detecting system with special data processing technique. Methods The system was consisted of stereomicroscope, CCD camera, etc. The images of amplitude measuring were captured and processed and the result was carried out at last. Results The measurement range for amplitude of transducer’s tip was above 190 ?m, the precision was below 10?m, and the repeatability was also ideal. Conclusion The amplitude measuring method has some excellent characters such as directness, simplicity, easy implementation, error estimableness and controllability, etc. It is proved in practice that the effect is nice and the blank in this field in China is filled.
