Rebecca Richards-Kortum, Ph.D., of Rice University, has devoted her profession to comprehension how technological innovation can make improvements to health and fitness and preserve life. Her new research focuses on creating very affordable screening tools for cervical most cancers, the fourth most popular most cancers amongst females throughout the world.
Imaging technological innovation has helped change this purpose into actuality. The technological innovation was developed with assistance from the National Institute of Biomedical Imaging and Bioengineering and the National Most cancers Institute.
Improving upon cervical most cancers detection
There are two principal difficulties in screening for cervical most cancers and human papillomavirus (HPV), the virus that results in cervical most cancers: It involves expensive tools and comprehensive lab operate.
“Both equally of these difficulties are definitely significant for clients who are medically underserved,” Dr. Richards-Kortum notes. “People could be clients who stay in rural areas or bad areas of the U.S. or in reduced- and middle-money international locations close to the planet.”
More than ninety% of cervical most cancers fatalities come about in reduced- and middle-money international locations, according to the Entire world Wellbeing Firm. Which is where by Dr. Richards-Kortum and her colleagues come in.
A moveable microscope
They’ve developed a reduced-price tag fiber optic microscope that makes it possible for health and fitness care vendors to see the exact same matters they would for the duration of a tissue biopsy. A biopsy is the most efficient way to diagnose cervical most cancers.
“We can make this technological innovation for really reduced price tag, it runs on a tablet personal computer, and it can be completely moveable and battery driven.”

“We can make this technological innovation for really reduced price tag, it runs on a tablet personal computer, and it can be completely moveable and battery driven,” she suggests.
It also involves much less instruction and experience to use. Typically, females with an irregular Pap smear have to have a treatment called a colposcopy. All through this treatment, a provider takes a tiny tissue sample from the cervix. The sample is despatched to a lab to be examined for most cancers cells. With the new technological innovation, vendors can consider a tissue sample, examine it, and follow up with the patient—all at the exact same time.
1st, a drop of dye is place on the tissue in a woman’s cervix. A tiny fiber-optic probe, about the size of a pencil, is carefully placed on the dyed tissue. The probe generates an impression of the tissue and cells that it sends again to a “microscope” on the tablet personal computer, where by the provider can assessment the impression for most cancers.
Improving upon follow-up rates
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 by they stay.
“It was definitely interesting to us to see the likely of anything not just in a middle-money place like Brazil, but to look suitable right here in our possess yard,” she suggests.
In addition to remaining very affordable and uncomplicated to transport, the microscope is also efficient. Dr. Richards-Kortum suggests that for the duration of field screening, the technological innovation had a level of precision really related to an professional gynecologist performing a tissue biopsy.
In a clinical trial in Brazil, teams identified that easier screenings helped to drastically make improvements to follow-up rates. “In females who had accessibility to this cell van, there was practically a forty% improve in the diagnostic follow-up,” Dr. Richards-Kortum suggests.
Dr. Richards-Kortum and her colleagues are also screening the technological innovation with oral most cancers.
The future of clinical technological innovation
Dr. Richards-Kortum notes that imaging technological innovation has more than just bodily health and fitness positive aspects. She has found how it can make improvements to patients’ comprehension of their possess health and fitness.
“It is definitely fascinating to see the electricity of imaging to assistance clients greater understand the improvements that are using put,” she suggests. “When a provider can stage out images and say, ‘This is what I see and this is why I’m anxious,’ it can be really satisfying.”
As a leader and mentor in the field of clinical technological innovation, Dr. Richards-Kortum is also centered on empowering future generations of bioengineers. She encourages more folks to review bioengineering and to consider on management roles in the field, primarily females.
“I believe for me, numerous of my colleagues, and the learners we operate with, it can be an remarkable option and privilege to believe of how you can use science and engineering to definitely make people’s life greater.”
