영문 초록

As the demand for bone mineral density testing increases in Korea, which is close to an aging society, it is necessary to evaluate the repeatability of equipment such as femur phantom other than l-spine for more accurate diagnosis. However, in clinical practice, it is often not possible to proceed such evaluation due to insufficient quality control conditions. Therefore, this study is to evaluate the usefulness of the femur phantom after fabricating the same using 3D printing technology. The femur phantom was output using GlowFill filament and FDM 3D printing type. Each phantom was repeatedly scaned 20 times to compare whether the existing l-spine phantom and the fabricated femur phantom were suitable as a phantom for quality control. Each time the seven researchers took three times, the location of the femur phantom was readjusted, and then scanned to confirm the error between the researchers. As a result of conducting repeatability evaluation using femur phantom, the coefficient of variation rate was 2%, which was within the minimum precision tolerance of 2.5%. The reproducibility between the researcher was also found to be suitable as the average coefficient of variation was 0.031 and the coefficient of variation rate was 3.1%, which was within the minimum precision error range of 5%. In conclusion, it is considered that the prospective attitude and usefulness of the femur phantom fabricated by 3D printing in clinical practice will be sufficient.
