Abstract
Method for making an orthosis of a body part of a person, wherein the method comprises of: —measuring the body part with a shape and in a pose in order to obtain measurement data of the body part; —correlating the measurement data of the body part to a predetermined statistical shape model of a corresponding reference body part in order to calculate parameters of the statistical shape model; —digitally forming an orthosis model on the basis of the statistical shape model with the known parameters; —producing the orthosis via a CAD/CAM system on the basis of the digitally formed orthosis model.
Claims10
A method for making an orthosis of a body part of a person, the method comprising:
- measuring the body part with a shape and in a pose in order to obtain measurement data of the body part;
- correlating the measurement data of the body part to a predetermined statistical shape model of a corresponding reference body part in order to calculate parameters of the statistical shape model;
- digitally forming an orthosis model on the basis of the statistical shape model with known parameters;
- and
- producing the orthosis via a CAD/CAM system on the basis of the digitally formed orthosis model, and
- wherein the method is preceded by the following steps of:
- selecting a plurality of reference persons, such that a shape of the reference body part of multiple reference persons differs;
- making a plurality of digital scans of the reference body part for each of the plurality of reference persons, wherein the reference body part is placed in multiple predetermined poses for making multiple ones of the plurality of digital scans;
- and
- constructing a statistical shape model on the basis of the digital scans.
A system for making an orthosis of a body part of a person, the system comprising:
- a first measuring device for measuring the body part with a shape and in a pose in order to obtain measurement data of the body part;
- a digital processing unit for correlating the measurement data of the body part to a predetermined statistical shape model of a corresponding reference body part in order to calculate parameters of the statistical shape model;
- a digital forming unit for digitally forming an orthosis model on the basis of the statistical shape model with the calculated parameters;
- and
- a CAD/CAM system for producing the orthosis on the basis of the digitally formed orthosis model,
- wherein the predetermined statistical shape model is formed by selecting a plurality of reference persons such that a shape of the reference body part of multiple reference persons differs and by making a plurality of digital scans of the reference body part for each of the plurality of reference persons, wherein the reference body part is placed in multiple predetermined poses for making multiple ones of the plurality of digital scans, and constructing a statistical shape model on the basis of the digital scans, wherein the first measuring device has an information density which is considerably smaller than the information density of a second measuring device with which the plurality of digital scans of the reference body part were made.
