Tomosynthesis is a medical image modality that can acquire tomographic images at low doses compared to X-ray CT. In this study, we aim to reconstruct tomosynthesis images from simple X-ray images that acquired by a portable X-ray system. Image acquisition was performed by attaching a calibration object with iron balls to the X-ray source housing. Geometry information was obtained from the arrangement of iron balls and the acquired X-ray image. Experiments assuming clinical use were conducted using a human phantom and a sectional image of an arbitrary depth could be successfully acquired. |
