4.1 Advantages of a Prototype 3D Craniofacial Imaging 
System for Craniofacial Soft Tissue Mapping 
The developed prototype 3D craniofacial imaging system is the 
first system developed in Malaysia for the purposed of 
craniofacial mapping. In term of 3D measurement of 
craniofacial soft tissue, the prototype 3D craniofacial imaging 
system developed in the study offered a non-contact method 
with better accuracy compare to the conventional method which 
used callipers for measuring craniofacial landmarks. Instead 
of acquiring one type of data which was implemented in most of 
craniofacial data acquisition system (which was published in 
journals), the developed system can be used to acquire two 
types of craniofacial spatial data which are (a) stereo images of 
craniofacial soft tissue, and (b) 3D surface model of 
corresponding craniofacial soft tissue captured in (a). Both data 
was acquired with patient remain seated for a few seconds. 
The acquired data (both stereo images and 3D laser surface) was 
process using appropriate software and the measurement of the 
landmarks was successfully obtained in 3D environment in the 
software, which was similar to conventional method using 
callipers. With the total weight of 30 kilograms, the imaging 
system was fully portable as mobile craniofacial imaging 
system. These were proved by a series of data collections at 
USM Hospital in Kota Bahru, Kelantan.
