چکیده

مدل‌سازی هندسی در فرآیند طراحی و ساخت نقش مهمی دارد و بسیاری از پژوهشگران ایده‌های خود را به صورت مدل‌های هندسی مورد تحلیل و آزمایش قرار دادند. مدل‌سازی هندسی نقش بسزایی در پیشرفت‌های صنعتی و علوم مهندسی دارد. در سال‌های گذشته در زمینه مدل‌سازی اعضا بدن انسان فعالیت‌های زیادی انجام شده است. در این پژوهش روشی برای مدل‌سازی استخوان از عکس‌های سی‌تی‌اسکن ارائه شده است. در این روش پس از اسکن استخوان مورد نظر با دستگاه سی‌تی‌اسکن داده خام مربوط به هر استخوان که شامل تعدادی مقاطع در سه جهت کرنال، محوری و ساجیتال است، در حافظه دستگاه سی‌تی‌اسکن ذخیره شده و بعد از استخراج این داده‌ها با استفاده از نرم‌افزارMicro Dicom که یک نرم‌افزار تبدیل‌کننده است پسوند فایل را به Dicom تغییر داده تا بتوان در نرم افزار اینوسالیوس اجرا کرد. در نهایت با انجام عملیات سه‌بعدی‌سازی با این نرم‌افزار، مدل به دست آمده به صورت فایل stl ذخیره می‌شود تا با استفاده از روش‌های نمونه‌سازی سریع مانند پرینتر سه‌بعدی مدل ایجادشده از استخوان ساخته شود.
