Rebecca Richards-Kortum, Ph.D., of Rice University, has devoted her profession to being familiar with how technological innovation can improve overall health and conserve life. Her recent analysis focuses on making very affordable screening equipment for cervical cancer, the fourth most common cancer between females throughout the world.
Imaging technological innovation has served convert this objective into actuality. The technological innovation was made with support from the National Institute of Biomedical Imaging and Bioengineering and the National Most cancers Institute.
Enhancing cervical cancer detection
There are two primary worries in tests for cervical cancer and human papillomavirus (HPV), the virus that brings about cervical cancer: It calls for pricey equipment and considerable lab work.
“Both of those of these worries are really significant for individuals who are medically underserved,” Dr. Richards-Kortum notes. “All those could be individuals who are living in rural spots or inadequate spots of the U.S. or in minimal- and center-money nations close to the world.”
A lot more than 90% of cervical cancer deaths occur in minimal- and center-money nations, according to the Planet Wellbeing Group. That’s where Dr. Richards-Kortum and her colleagues occur in.
A moveable microscope
They have made a minimal-price tag fiber optic microscope that permits overall health care providers to see the same things they would through a tissue biopsy. A biopsy is the most efficient way to diagnose cervical cancer.
“We can make this technological innovation for extremely minimal price tag, it runs on a tablet personal computer, and it is totally moveable and battery run.”

“We can make this technological innovation for extremely minimal price tag, it runs on a tablet personal computer, and it is totally moveable and battery run,” she states.
It also calls for significantly less schooling and expertise to use. Usually, females with an abnormal Pap smear have to have a treatment known as a colposcopy. In the course of this treatment, a supplier requires a small tissue sample from the cervix. The sample is despatched to a lab to be examined for cancer cells. With the new technological innovation, providers can just take a tissue sample, take a look at it, and adhere to up with the patient—all at the same time.
Initially, a fall of dye is place on the tissue in a woman’s cervix. A small fiber-optic probe, about the measurement of a pencil, is gently positioned on the dyed tissue. The probe creates an picture of the tissue and cells that it sends again to a “microscope” on the tablet personal computer, where the supplier can assessment the picture for cancer.
Enhancing adhere to-up charges
Dr. Richards-Kortum and her colleagues analyzed the technological innovation in cell diagnostic vans. They traveled close to the Rio Grande Valley in Texas and in Brazil, bringing screening to females where they are living.
“It was really fascinating to us to see the probable of a little something not just in a center-money place like Brazil, but to glimpse right right here in our personal backyard,” she states.
In addition to being very affordable and effortless to transportation, the microscope is also efficient. Dr. Richards-Kortum states that through area tests, the technological innovation experienced a level of precision extremely comparable to an qualified gynecologist undertaking a tissue biopsy.
In a medical demo in Brazil, groups observed that a lot easier screenings served to significantly improve adhere to-up charges. “In females who experienced entry to this cell van, there was almost a forty% enhance in the diagnostic adhere to-up,” Dr. Richards-Kortum states.
Dr. Richards-Kortum and her colleagues are also tests the technological innovation with oral cancer.
The potential of healthcare technological innovation
Dr. Richards-Kortum notes that imaging technological innovation has extra than just actual physical overall health gains. She has noticed how it can improve patients’ being familiar with of their personal overall health.
“It can be really exciting to see the ability of imaging to support individuals superior comprehend the improvements that are having position,” she states. “When a supplier can place out pictures and say, ‘This is what I see and this is why I’m anxious,’ it is extremely rewarding.”
As a chief and mentor in the area of healthcare technological innovation, Dr. Richards-Kortum is also concentrated on empowering potential generations of bioengineers. She encourages extra people today to research bioengineering and to just take on management roles in the area, specifically females.
“I think for me, a lot of of my colleagues, and the learners we work with, it is an incredible prospect and privilege to think of how you can use science and engineering to really make people’s life superior.”
