Innovative technology is making many medical applications easier to perform than in days past. For instance, medical examinations of all facets have minimal impact on the patient, thanks to 3D scanning. Using a 3D digital scanner for medical equipment, patients have no fear of pain from invasive tests. The scanner has no contact with the patient, but allows measurements in areas impossible to reach with previous devices.

The concept behind the 3D digital scanning is a simple format once one understands what is involved. A line of laser light digitally captures the shape of physical objects in a non-destructive manner. The scanner then creates data from the surface of the object. This is a way to demonstrate the exact size and shape of the object in a 3-dimensional representation. 3D laser scanner captures free-form shapes and quickly generates millions of points on a computer. 3D laser scanning is ideal for contoured or complex surfaces that may require extreme amounts of data for an accurate description. The traditional method would likely require some sort of touch probe.

Using a 3D digital scanner for medical equipment allows the scanner to measure fine details with little to no contact with the patient. The process will capture shapes accurately and quickly. The initial step has a patient lying on the digitizer, more than likely a bed form. Software then guides a laser probe above the surface of the patient in the area of concern. The laser probe projects a line of laser light onto a surface while sensor cameras record the distance and shape of the laser line in 3D form.

The image appears as millions of points called a “point cloud” on a computer monitor until the entire shape forms. At the end of the rendering of the point cloud, a 3D representation generates. Depending on the software, the image is then ready for the next step of inspection.

This method is the fastest way to provide 3D digital data for reverse engineering. This is the process used to create a CAD model of the image. This model can indicate imperfections or areas of concern. This application is limitless in the medical industry.

Doctors now have the ability to analyze a patient’s area of concern in a 3D form. One can strategically go about treating the patient having seen the 3D model of the issue. Dental applications can mold precisely using this new technique, allowing a more exact fit as the result.

This technology is making strides in the medical field; however, the advantages have the ability to influence industries all over the world. Using 3D scans, one can capture all of the physical measurements of any object quickly and accurately. The time one will save using 3D scans allows more time solving problems. The reverse engineering of the image allows one to make sure all parts fit together and work smoothly the first time. One will be able to capture engineering optimizations inherent in manufactured parts. The ability to utilize modern manufacturing of parts is cost efficient. Many of these parts, made by hand before the time of CAD, are no longer be needed.
