| Abstract(in English) | In medical image diagnosis using X-rays, various methods have been studied to remove scattered rays as they pollute diagnostic information. The most used method for that purpose is a collimator, which called the grid, between the subject and the X-ray detector. In recent years, demands of portable X-ray equipment has been increasing for home medical care or inpatients due to the aging. In such portable devices, it is difficult to properly attach the grid, so it is often not used, which may cause diagnostic problems. In this paper, as a method of removing scattered rays without using a grid, we constructed a new method of removing scattered X-rays by a moving beam stopper and an FPD which can collect time-continuous data. Numerical examples are presented to show effectiveness. |
