Computer-aided design (CAD) is the use of computer systems (or workstations) to aid in the creation, modification, analysis, or optimization of a design.
CAD output is often in the form of electronic files for print, machining, or other manufacturing operations. The term CADD (for Computer Aided Design and Drafting) is also used.
CAD may be used to design curves and figures in two-dimensional (2D) space; or curves, surfaces, and solids in three-dimensional (3D) space.
For many patients, advanced 3D imaging and use of medical CAD software can improve the accuracy of treatment planning and the precision of surgical execution 1).
To convert DICOM files to the standard 3D image format, another piece of software such as ScanIP (Synopsys Inc., Mountain View, CA, USA) or Osirix (Pixmeo SARL, Geneva, Switzerland) should be used. However, with recent advancements in medical CAD software, this software has become more intuitive and simpler. In addition to Mimics we used, Dolphin Imaging (Dolphin Imaging and Management Solutions, Chatsworth, CA, USA) and Maxilim (Medicim, Mechelen, Belgium) were known as medical CAD software 7).
As medical computer-aided design (CAD) has improved, virtual 3-dimensional medical images have been gaining more easily without any special practice. These images can be applied to various clinical fields. This article illustrates virtual preoperative simulation for excision of spinal tumors using medical CAD software. The software was used directly by the surgeon. The process of virtual preoperative simulation for spinal tumor surgery was found to be not inordinately complicated. And, virtual simulation was helpful in determining surgical steps as well as understanding the surgical anatomy 8).
