Figure 4: The percentage variation (1 h/28 d) of osteogenesis capability (up the 100% horizontal ordinate, the CT value, and ultrasound GV ratio of 1 h/28 d) and degradation property (under the 100% horizontal ordinate, CT mask volume, and ultrasound section pixel of 1 h/28 d) via CT and ultrasound (data from Table 3). As same as CT, ultrasound shows that the osteogenesis capability and degradation property are better in CS/nHAC than in CS.
