Background: At present the interest in medical field about the generation of three-dimensional digital models of anatomical structures increases due to the widespread diffusion of CAS - computer assisted surgery - systems. Most of them are based on CT computer tomography - or MR - magnetic resonance - data volumes but sometimes this information is not available; there are only few X-ray, ultrasound or fluoroscopic images. Methods: This paper describes the study and the development of a script for a commercial software package (ads Max) able to reconfigure the template model of a femur starting from two orthogonal images representing the specific patient's anatomy. Results: The script was used in several tests as summarized in this paper and the results appear to be interesting and acceptable, even for the medical experts that evaluated them. Conclusions: The script developed in this work allows the generation of the 3D model of a femur in a very simple way (the user interface has been developed obeying to the main usability guidelines) and using a widespread commercial package. The quality of the results can be compared to the quality of more expensive and specialized systems. (c) 2007 Elsevier Ireland Ltd. All rights reserved.

Abstract

Background: At present the interest in medical field about the generation of three-dimensional digital models of anatomical structures increases due to the widespread diffusion of CAS - computer assisted surgery - systems. Most of them are based on CT computer tomography - or MR - magnetic resonance - data volumes but sometimes this information is not available; there are only few X-ray, ultrasound or fluoroscopic images. Methods: This paper describes the study and the development of a script for a commercial software package (ads Max) able to reconfigure the template model of a femur starting from two orthogonal images representing the specific patient's anatomy. Results: The script was used in several tests as summarized in this paper and the results appear to be interesting and acceptable, even for the medical experts that evaluated them. Conclusions: The script developed in this work allows the generation of the 3D model of a femur in a very simple way (the user interface has been developed obeying to the main usability guidelines) and using a widespread commercial package. The quality of the results can be compared to the quality of more expensive and specialized systems. (c) 2007 Elsevier Ireland Ltd. All rights reserved.
