Orthopedic Software Addresses Orthotics Problems

PRECISION TECHNOLOGY NEWS

Crispin, a wholly owned subsidiary of Delcam plc, has unveiled a PC-based system that uses a multimodule process to address orthotics.

The process begins with OrthoScan, a portable, variable resolution 3-D laser foot, last, and cast scanner. The unit scans the entire foot and provides STL data for export into the next module, OrthoLast.

OrthoLast imports the STL format and an existing last, similar to that of the scanned foot, is selected from a library and merged with the foot template. Measurements and characteristics are modified to mirror those of the scanned foot. OrthoDesign appends existing designs directly onto the customer's last and customizes the last with any specific requirements. Depth, materials, textures, and colors can be added to the design elements, along with features like stitching, padding, eyelets, and laces. The software generates photorealistic images so that designs can be reviewed without building a sample.

The OrthoTec module is used to develop 2-D orthopedic footwear patterns. A multipoint transformation function transposes an existing 2-D pattern onto the new last form created from the original scanned foot data.
