How do medical models for surgeons work?

Developing the method of fabricating lifelike artificial organs was a process of trial and error and began more than two years ago when Ghazi, a urological surgeon and educator, was introduced to Stone who has a background in engineering, a passion for developing new medical devices, and, most importantly, access to a 3D printer.

The process begins with images obtained from MRI, CT, or ultrasound scans into computer-assisted designs (CAD).  Instead of using these designs to create rigid plastic replicas of human anatomy, which was already being done in many other places, the pair instead converted the CADs of organs into molds, or negatives, which were built using a 3D printer.  In a process akin to casting a bronze statue, the molds are then injected with a hydrogel which, after freezing, assumes a solid state.

no, because those are both different running competitions. while distance runners train their legs and their lungs to run long amounts of time, the sprinters are training their legs and their lungs to give all they have in the little amount of area they need to cover. the brain also plays a huge part in all of this.

the brain is the only thing in your body that sends messages to your body telling you to run. if you are a long distance runner and you have the mind set of a sprinter, you will not get anywhere. if you have a long distance mind set and you have to run 200m in 20 seconds then you will not make it in time.
