Flat feet, sagging arches, asymmetrical soles, heel flips… these issues tend to affect the comfort and overall health of walking.
Just as eyeglasses can accurately correct vision, 3D foot laser scanner can reflect the structure of the foot through high-precision measurements, providing scientific evidence for the diagnosis and intervention of flat feet.
Scanners need to measure not only accurately, but also accurately. In addition to the precision of the hardware, it must be combined with scientific algorithms and data analysis. So why are 3D foot laser scanner so accurate at measuring flat feet? This is mainly reflected in the following:
I. High-precision three-dimensional modelling
1.Totally capturing foot shape.
Three-dimensional laser scanner can capture hundreds of thousands to more than a million foot surface points in a very short period of time and construct a complete three-dimensional model. For flat-footed patients, it clearly displays subtle changes that occur when the arch collapses, the distribution of pressure between the forefoot and back feet, and the angle of heel, avoiding details that cannot be captured by conventional measuring tools or two-dimensional photography.
2.Precise measurement of angle and length
The device can accurately calculate key indexes such as arch height, heel inclination and forefoot width. This allows doctors or therapists to quantify the severity of flat feet and provide accurate data to support the development of correction plans. Numerically, the difference between abnormal and healthy feet was clearly visible.
ii. Personalized data analysis
1.Tailored for Everyone
Foot morphology, arch height, bone structure and ligament elasticity vary from person to person. The 3D laser scanner integrates biomechanical analysis and gait assessment to achieve personalized foot analysis along with morphological data. For flat-footed patients, it pinpoints cave-ins, pressure points and potential injury risks.
2.Dynamic simulation of change
Some high-end scanners that support dynamic gait scanning can observe how the arch compresses and bounces when walking or running. By combining dynamic data with static data, doctors can fully assess flat feet, not only their structural abnormalities.
III. Advanced algorithms and model matching
1.Intelligent analysis of plantar surface curves of the foot
The software accompanying the scanner uses advanced 3D surface fitting algorithms to transform captured point cloud data into a visualization model. The low arch, valgus tendency and forefoot pressure of flat-footed patients can be accurately labeled to ensure scientific, effective and reliable measurement results.
2.Comparison with database samples
By the patient’s data with large numbers of healthy foot and flat-foot samples, scanners can provide standardized reference indicators to help clinicians determine the severity of abnormalities and guide personalized correction plans.
IV. INTRODUCTION Non-invasive, efficient and repeatable
1.Contactless measurement
The 3D laser scanner adopts non-contact measuring technology, which avoids compression or deformation of the foot caused by traditional tools and ensures the authenticity and reliability of the data.
2.Rapid measurement and long-term follow-up
The scan usually takes between a few seconds and a dozen seconds to collectfoot data. Rectification can be repeated at any time to facilitate monitoring and evaluation of the progress of rectification and to formulate long-term scientific intervention plans.
V. the groundwork for rehabilitation and rehabilitation
1.Assist in customizing orthotic insoles
The precise 3D model generated by the scanning data can be directly used to design customized orthotic insoles to ensure perfect alignment with the patient’s foot, provide proper arch support, and reduce foot pressure.
2.Guide rehabilitation training
3D data helps therapists develop targeted foot muscle training and correction plans. In addition to insole support, flat-footed patients can improve arch function through exercise to achieve comprehensive intervention.
