LSU students 3D print a complete "human" for radiation therapy research
On December 17, 2018, it was learned from foreign media that Meagan Moore, a bio-agricultural engineering student from Louisiana State University (LSU), had 3D printed a full-size " human body " for radiation therapy research.
The Phantom project, also known as Mary, is made of bioplastics that can be filled with water to create different densities similar to patients. It can help test the radiation of people of real size to find the optimal angle of dose distribution.
Moore said: "For decades, Phantoms has been used in medicine and health physics. As a substitute for human tissue, the problem is that most dosimetry models are based on standards when people of all sizes have cancer. There is currently no personalized body model."
Although the current Phantoms cost $40,000, no limbs, and does not represent every size, Moore's female Mary has a body with four limbs that can be created for $500.
Mary used five real-life 3D scan simulations to divide the four-part 3D print on the BigRep 3D printer, which took a total of 136 hours. In order to join these parts, Moore used a combination of polishing, welding and sand blasting. Standing 5 feet and 1 inch and weighing 15 pounds, Mary can hold 36 gallons of water for up to four and a half hours.
Moore said: "I specifically want to work with women, because in science, women are usually not considered complicated for various reasons, I want a person with the most complex geometry."
In October of this year, Mary was taken to the University of Washington Medical Cyclotron facility in Seattle, where researchers were interested in her fast neutron treatment. This type of treatment - a specialized and powerful form of external beam radiation therapy - is commonly used to treat certain radiation-resistant tumors, which means they are extremely difficult to kill using X-ray radiation therapy.
Mary's trip was supported by the Director of the Medical Physics Program at Louisiana State University and Professor Wayne Newhauser, who served as Moor's Phantom program mentor.
“The initial idea of ​​the whole project was not entirely my idea,†Moore said. “Dr. Becky Carmichael [LSU Communication Course Science Coordinator and TEDxLSU Speech Coach] told Dr. Newhauser that he should talk to me. I met him in his TED talk, where he did an introduction about 3D printing, I Show me my 3D printing. This project starts with the work of breast cancer and computer modeling."
Moore hopes that Mary's personalized replica will be created and used in the medical field to more accurately treat cancer patients.
