Rebecca Richards-Kortum, Ph.D., of Rice University, has devoted her occupation to knowing how technologies can enhance wellness and preserve lives. Her the latest research focuses on building reasonably priced screening instruments for cervical most cancers, the fourth most common most cancers between women globally.
Imaging technologies has aided convert this purpose into actuality. The technologies was developed with support from the National Institute of Biomedical Imaging and Bioengineering and the National Most cancers Institute.
Strengthening cervical most cancers detection
There are two primary issues in screening for cervical most cancers and human papillomavirus (HPV), the virus that brings about cervical most cancers: It involves expensive instruments and in depth lab get the job done.
“Each of these issues are truly significant for people who are medically underserved,” Dr. Richards-Kortum notes. “Those people could be people who live in rural regions or weak regions of the U.S. or in reduced- and middle-revenue countries close to the environment.”
Extra than ninety% of cervical most cancers deaths materialize in reduced- and middle-revenue countries, in accordance to the World Wellness Group. That’s wherever Dr. Richards-Kortum and her colleagues appear in.
A portable microscope
They have developed a reduced-value fiber optic microscope that permits wellness care suppliers to see the exact same factors they would through a tissue biopsy. A biopsy is the most helpful way to diagnose cervical most cancers.
“We can make this technologies for extremely reduced value, it operates on a pill computer, and it truly is completely portable and battery driven.”

“We can make this technologies for extremely reduced value, it operates on a pill computer, and it truly is completely portable and battery driven,” she states.
It also involves a lot less education and skills to use. Generally, women with an irregular Pap smear have to have a technique known as a colposcopy. In the course of this technique, a supplier usually takes a small tissue sample from the cervix. The sample is sent to a lab to be examined for most cancers cells. With the new technologies, suppliers can get a tissue sample, take a look at it, and abide by up with the patient—all at the exact same time.
Very first, a drop of dye is set on the tissue in a woman’s cervix. A small fiber-optic probe, about the size of a pencil, is gently positioned on the dyed tissue. The probe results in an picture of the tissue and cells that it sends back again to a “microscope” on the pill computer, wherever the supplier can critique the picture for most cancers.
Strengthening abide by-up charges
Dr. Richards-Kortum and her colleagues examined the technologies in cell diagnostic vans. They traveled close to the Rio Grande Valley in Texas and in Brazil, bringing screening to women wherever they live.
“It was truly exciting to us to see the potential of a thing not just in a middle-revenue country like Brazil, but to glimpse right here in our have yard,” she states.
In addition to becoming reasonably priced and effortless to transportation, the microscope is also helpful. Dr. Richards-Kortum states that through area screening, the technologies had a amount of precision extremely similar to an pro gynecologist accomplishing a tissue biopsy.
In a medical trial in Brazil, groups found that much easier screenings aided to drastically enhance abide by-up charges. “In women who had accessibility to this cell van, there was virtually a 40% raise in the diagnostic abide by-up,” Dr. Richards-Kortum states.
Dr. Richards-Kortum and her colleagues are also screening the technologies with oral most cancers.
The long run of professional medical technologies
Dr. Richards-Kortum notes that imaging technologies has additional than just actual physical wellness gains. She has noticed how it can enhance patients’ knowing of their have wellness.
“It’s truly intriguing to see the electric power of imaging to assistance people greater comprehend the alterations that are using place,” she states. “When a supplier can stage out images and say, ‘This is what I see and this is why I’m involved,’ it truly is extremely gratifying.”
As a leader and mentor in the area of professional medical technologies, Dr. Richards-Kortum is also focused on empowering long run generations of bioengineers. She encourages additional individuals to study bioengineering and to get on management roles in the area, especially women.
“I feel for me, several of my colleagues, and the college students we get the job done with, it truly is an amazing prospect and privilege to feel of how you can use science and engineering to truly make people’s lives greater.”
