3D leg scanning makes it possible to capture the morphology of the lower limbs directly from a smartphone. Foot, ankle, leg or knee area: professionals can obtain a usable 3D model, with no dedicated 3D scanner or specialized hardware.
This approach simplifies digital measurement in orthotics, medical compression and morphological monitoring. It helps professionals work from data that is more precise, more reliable and easier to integrate into their business tools.
In this article, discover how to perform a 3D leg scan from a mobile device, and how this technology can support custom device design, compression product fitting and lower-limb monitoring.
Obtain a 3D model of the legs from a mobile device
Mobile 3D scanning for orthotics
For a long time, measurement in orthotics relied on manual methods: tape measurement, molding, impressions or patient travel. These steps can be time-consuming, vary from one operator to another and be difficult to integrate into a digital workflow.
Today, 3D leg scanning makes it possible to capture lower-limb morphology in just a few seconds. From a smartphone, professionals can obtain a usable 3D model, ready to be used in their existing tools.
At MyFit Solutions, the technology is based on mobile photogrammetry. This approach reconstructs a body part in 3D from images captured by the smartphone, with no dedicated 3D scanner or specialized hardware.
For healthcare professionals, the value is concrete: it simplifies digital measurement, makes morphological data more reliable and supports the design or fitting of custom devices, such as orthoses, prostheses or compression stockings.
Why perform a 3D leg scan?
3D leg scanning makes it possible to capture lower-limb morphology with precision. It provides professionals with a reliable digital base to visualize shapes, extract measurements and better understand the patient’s anatomy.
This data is particularly useful for orthoses, prostheses and compression stockings. By using a 3D model of the legs, professionals can design or adjust devices that are better adapted to each patient’s morphology.
Mobile 3D scanning can also support morphological monitoring over time. After surgery, during treatment or as part of rehabilitation, it helps observe changes in the legs, knees, ankles or feet.
For healthcare professionals, the value is clear: they obtain data that is more precise, faster to capture and easier to compare. 3D leg scanning therefore becomes a valuable tool to personalize devices, adjust care and improve patient follow-up.
How to scan legs in 3D with an iOS or Android mobile device
The MyFit Solutions technology is available from iOS and Android smartphones. It helps professionals perform a 3D leg scan more easily, with no dedicated 3D scanner or specialized hardware.
Here are the main steps to obtain a 3D model of the lower limbs from a mobile device.
Step 1: use a mobile 3D scanning app
To perform a 3D leg scan, professionals first need access to a dedicated application. MyFit Solutions offers several options depending on the need: a ready-to-use application, a white-label solution or an SDK integration.
In every case, the goal remains the same: to help professionals integrate a mobile 3D scanning experience into their business workflow, with a simple and guided interface.
Step 2: prepare the scanning environment
Before starting the capture, it is important to prepare the environment. Lighting should be sufficient and even, in order to avoid shadows or reflections that could affect scan quality.
The subject should also adopt a stable position, adapted to the use case. This preparation helps obtain a clearer, more reliable and more usable capture.
Step 3: scan the legs in 3D
Once the application is open and the subject is ready, the professional follows the instructions displayed on the screen. The scan is guided step by step to make it easier to capture the legs, knee, ankle or foot.
The smartphone camera captures the required images. They are then processed using mobile photogrammetry to generate a precise and usable 3D model of the legs.
Step 4: obtain the 3D model and leg measurements
After the scan, the professional can access the 3D model and digital measurements from the application or the associated web platform.
The models can be visualized, downloaded or integrated into existing digital processes through standard connectors, such as APIs and Webhooks.
3D leg scanning therefore becomes a simple solution to capture the lower limbs, obtain reliable morphological data and use it in a design, fitting or patient monitoring workflow.
Creating and fitting custom products with 3D leg scanning
3D leg scanning makes it possible to capture lower-limb morphology with a high level of precision. This data can then be used to personalize medical devices, recommend a size or monitor changes in the patient’s morphology over time.
At MyFit Solutions, the approach is based on body-part-specific capture. The goal is to obtain a usable 3D model, adapted to each use case, from a standard smartphone.
Creating custom leg orthoses and prostheses
3D leg capture can support the design of orthoses and prostheses adapted to the lower limbs. It can be used, for example, for knee-ankle-foot devices such as KAFOs.
Thanks to the 3D model obtained, professionals have a reliable digital base to better understand patient morphology and prepare a more precise fit. 3D leg scanning therefore helps improve comfort, fit and personalization.
Recommending the right size for compression stockings
Mobile 3D scanning can also help recommend the right size for compression stockings. By capturing the volumes and dimensions of the lower limbs, it provides data that is more reliable than manual measurement.
This approach can be useful in different care pathways: medical compression, lymphoedema monitoring, venous insufficiency or post-surgery support. Professionals can rely on precise digital measurements to guide product selection.
Monitoring morphological changes in the legs, knees and feet
Beyond device design, 3D leg scanning can help professionals monitor morphological changes in the lower limbs. It makes it possible to compare data over time, especially after surgery, during rehabilitation or as part of medical follow-up.
This digital visualization provides complementary data for healthcare professionals. It can help them better observe changes, adapt follow-up and document patient evolution.
3D leg scanning: a tool to better use morphological data
3D leg scanning enables professionals to capture the lower limbs in a simple, fast and precise way. From a smartphone, they can obtain a usable 3D model, with no dedicated 3D scanner or specialized hardware.
This approach simplifies digital measurement, device personalization and morphological monitoring over time. It also supports smoother workflows, where data can be stored, compared and integrated more easily into professional tools.
For professionals in orthotics, medical compression or patient monitoring, 3D leg scanning becomes a concrete solution to improve precision, efficiency and quality of care.
