A comparative study between traditional head measurement and structured light three-dimensional scanning when...

Area of Science:

• Craniofacial anthropometry
• Medical imaging
• Pediatric health

Background:

• Infant skull shape assessment is crucial for early detection of abnormalities.
• Traditional methods and advanced 3D scanning are used for head measurements.
• Evaluating the consistency between these methods is essential for clinical practice.

Purpose of the Study:

• To compare the correlation and consistency of infant head measurements obtained via traditional methods and structured light 3D scanning.
• To determine the suitability of each method for assessing infant skull morphology.

Main Methods:

• Seventy-six infants (3 months to 2.5 years) were included.
• Traditional measurements included head circumference (HC) and diameters using calipers.
• Structured light 3D scanning was used to capture cranial parameters.

Main Results:

• High correlation (r=0.793-0.980) was found between traditional and 3D scanning methods for most parameters.
• Correlation coefficients for transverse, anteroposterior diameters, HC, and CI of symmetry exceeded 0.9.
• Bland-Altman plots indicated reasonable consistency between the two measurement approaches.

Conclusions:

• Both traditional and 3D scanning methods are effective for measuring infant head shape.
• Traditional methods are economical for general screening.
• Structured light 3D scanning provides valuable additional data for abnormal head shapes and custom helmet design.
