| Research Abstract |
Since X-ray CT examination is one of the leading procedures in health clinics,actual X-ray CT equipments are used for testing and training in educational institutions that train medical radiological technicians. However,a real-life X-ray CT equipment is large and has a complicated internal structure,so the testing and training curriculum is limited for helping students comprehend the electrical and image analysis principles of the equipment,and it is also necessary to consider the dangers of exposure to X-rays. For that reason,there is demand for a simpler educational equipment that achieves such objectives.
In 2006,we made the equipment smaller by simplifying the method of detecting transmitted light,and created a new prototype of a simpler simulated CT equipment for educational purposes that enables simultaneous us by several such equipments.We reduced the size of the system and enabled shorter data collection times by using a pocket computer to control the stepper motor and collect transmitted light strength data.We consider that this simple system is useful for application in introductory courses,to help students understand the structure and image processing of an X-ray CT equipments.
In 2007,we clarified the directionality and selectivity of the rectilinear light component in optical heterodyne interferometry and the relationship between the scan interval of the rotational stage and artifacts on the simulated CT image.We also reconstructed sectional images in the heightwise direction to create a three-dimensional image. In addition,we clarified the relationship between the surface texture of the phantom container and artifacts on the simulated CT image.
