Recent advances in personalized 3D modeling make it possible to consider personalized hand modeling based on cone-beam CT. The goal is to develop a personalized 3D modeling tool for use in routine clinical practice that reduces both the radiation dose to which patients are currently exposed during CT scans and the time required to process CT data (segmentation). the main, objective of the study is to compare the quality of 3D hand modeling based on cone-beam CT with the gold standard of computed tomography.

This prospective, single-center, interventional study will include 6 healthy volunteers.

Inclusion Criteria:

• no clinical symptoms suggestive of a wrist ligament injury (e.g., pain, instability)
• no contraindications to undergoing a CBCT scan (e.g., pregnancy, history of hypersensitivity to radiation).
• Enrolled in or eligible for a French social security plan.
• Signing of an informed consent form indicating that the subject understands the purpose and procedures required by the study and agrees to participate in the study and comply with the requirements and restrictions inherent to this study

Exclusion Criteria:

• Pregnant women and breastfeeding mothers
• Persons deprived of their liberty by a judicial or administrative decision; persons undergoing involuntary psychiatric treatment; persons admitted to a health or social care facility for purposes other than research
• Adults subject to a legal protection measure (judicial protection, guardianship, or conservatorship) or who are unable to give consent
