What makes a pregnant woman afraid of going to doctor? Radiation to fetuses may become an answer, since fetuses are extremely sensitive to radiation. Radiation is a doubled-edged sword: It holds the power to cure cancer, but if used improperly it can also cause serious damage to the human body. On the other side, it is known that expecting mothers have a need of cancer screening.
Recently, researchers from Rensselaer Polytechnic Institute have developed a new set of modeling tools that could enable safer, more accurate, and more effective radiation therapy and nuclear medicine imaging procedures for pregnant women.
The leader of the project, George Xu, professor of nuclear and biomedical engineering at Rensselaer, said that they took an entirely new approach, using advanced computer simulations to determine the correct dose of radiation to administer to patients.
These computer simulations are based on sophisticated virtual models of the human body. About 30 of these models, sometimes called “phantoms,” have been developed worldwide. The new models should be extremely useful for understanding the risks of radiation, and for better planning radiation imaging and treatment for pregnant women. The tools used in this method is BREP, boundary representations. This tools is more flexible and features a more robust toolbox for manipulating the surface of model components, and also highly effective for creating medical phantoms consisting of complex organs.
