“…The maximum AE obtained with Gemini structured-light scanning was 0.94 mm. This finding is comparable with the results of other studies on the accuracy of structured-light scanning applications 27 , and other imaging applications used for obtaining measurements of the hand 1,28 . Although the Gemini structured-light scanning system has not been employed for the clinical measurement of hand, the results of our study are encouraging.…”

“…Continuous improvement in technology and software has made it possible for researchers and clinicians to achieve realistic 3D imaging, although it may never be fully attainable. Furthermore, Lee et al reported that subjective satisfaction achieved with the 3D semiautomatic measurement protocol (3D-SAMP) with respect to ease of hand measurement was significantly greater than that achieved for the direct measurement protocol 28 . This made the 3D-SAMP more preferable to direct measurement because of the shorter interaction time with the subject.…”

The aim of this study was to identify an efficient approach for 3D imaging of hand. The 3D photographs of hand were taken with Gemini structured-light scanning system (SL scanning) and CT scanning. The 3D photographs, average time of scanning and reconstruction were compared between these two indirect techniques. The reliability, reproducibility and accuracy were evaluated in these two indirect techniques and the direct measurement (DM). Statistical differences in the measurements were assessed by 99% probability, with clinical significance at > 0.5 mm. The Gemini structured-light scanning system established a complete and smooth 3D hand photograph with shorter scanning and reconstruction time. Reproducibility of CT scanning and SL scanning methods was better (P < 0.01, both) than the DM, but did not differ significantly from each other (P = 0.462). Of the 19 (31.58%) measurements obtained, 6 showed significant differences (P < 0.01). Significant differences were observed more often for circumference dimensions (5/9, 55.56%) than for length dimensions (1/10, 10%). Mean absolute error (AE) of the 10 subjects was very low for 3D CT (0.29 ± 0.10 mm) and SL scanning (0.30 ± 0.11 mm). Absolute percentage error (APE) was 4.69 ± 2.33% and 4.88 ± 2.22% for 3D CT and SL scanning, respectively. AE for the PIP circumference between the 3rd finger (0.58 mm) and 4th finger (0.53 mm) scan was > 0.5 mm, indicating significant difference between DM and CT scanning at the level of 99% probability. In this study, the Gemini structured-light scanning system not only successfully established a complete and smooth 3D hand photograph, but also shortened the scanning and reconstruction time. Compared to the DM, measurements obtained using the two indirect techniques did not show any statistically or clinically insignificant difference in the values of the remaining 17 of 19 measurements (89.47%). Therefore, either of the two alternative techniques could be used instead of the direct measurement method.
