 note = {application/pdf, Soil macro pores are quantitated by number, size, shape, direction and so on. However, soil matrix structure which consists of a lot of soil particles, aggregates and their arrangements of varied size and shape is difficult to quantitate. Soft X-ray Digital Radiography (SXDR) was developed from a viewpoint that a soft X-ray image of soil  has information of soil structure. On the SXDR, soil matrix structure was quantitated by the result of the image processing of soft X-ray digital images. In this paper, overview of SXDR, and measurement of soil structure by SXDR are indicated. The contents of this paper are as following.
(1) Principle and procedure of SXDR were described (2) Particle size of glass beads and sand were measured by SXDR
(3) Area Density of Soil (ADoS) was defined and it was measured by SXDR
(4) Cracks on bentonite were observed by SXDR
(5) Water content and suction were measured by SXDR},
