Abstract:
1. A three dimensional digitizing system for designing external medical devices comprising: a direct scanning laser device for scanning an exterior of a patient's body part, said laser device comprising a digital camera, a laser light source and an electromagnetic receiver, said laser device being structured and disposed to produce a plurality of laser lines read by said laser device and being structured and disposed to create contour coordinates of the exterior of said body part, said laser device comprising a transmitter within the laser device designed to generate a three-dimensional magnetic field; a two-channel motion-tracking device designed to track the object's movement in relation to the laser device, said two-channel motion-tracking device comprising a reference receiver capable of tracking the body part's position and a position of the laser device relative to the body part; and a processing unit (PU), said processing unit comprising electronics for the two-channel motion-tracking device, video processing electronics and connections for the laser device, the reference receiver, the computer interface and a power source, and being structured and disposed to calculate a three-dimensional digital image of said body part by using data received by said laser device, said transmitter and said two-channel motion tracking device; wherein said laser device further includes an optical stylus to create a digital landmark on the contour coordinates, wherein the optical stylus has a first position at which the laser device creates contour coordinates of the exterior of said body part, the optical stylus having a second position at which the laser device focuses the laser light to create a digital landmark on the contour coordinates, said digital landmark comprising a plurality of data, consisting of multiple coordinates corresponding to a section of the patient's body part; wherein the system is capable of storing the digital landmark; wherein the digital image can be used to create an external medical device and the digital landmark can be used to modify the medical device to customize the external medical device.
