Innovating in the Classroom: Oregon Tech’s “Hands-on” Medical Imaging Programs Adapt to COVID-19 Using Custom Cameras

Jul 06, 2020
Accepting the need for remote learning in a course that requires hands-on learning, Oregon Tech’s Medical Imaging faculty turn to custom camera setups for answers

TAs position patient for virtual technologistWith Spring term courses quickly transitioning to remote delivery, Oregon Institute of Technology, “Oregon Tech,” assistant professor Rich Carson had to find ways to still provide the hands-on focus that his Radiologic Science bachelor’s degree program is known for. How does a program that requires hands-on interaction with patients transition to virtual delivery? Through collaborating with one of Oregon Tech’s information technology experts, Scotty Hayes, to create a virtual environment. With this transformation, sophomores in Carson’s radiographic positioning class were able to navigate between three different camera options in the lab on campus to create a “hands-on” environment.

To evaluate the success of his new “classroom,” Carson used the setup to hold his end-of-term exams. Equipped with full protective gear, only three people—usually the same teaching assistants—are in the room when each separate exam is conducted. This greatly limits any potential exposure a class of 50 students in the course would previously require, where students typically spend 50 to 100 hours each term in preparation for the competency exam.

Virtual Technologist instructs positioningThe scenario:

  • From his office in the Martha Anne Dow Center for Health Professions, Carson provides a health scenario to the student taking an exam through a Zoom call.
  • A “patient” shows up for their appointment at Oregon Tech’s Radiologic Science lab to get X-rays from the virtual technologist.
  • The student technologist completes an assessment with the patient over Zoom on basic health history and current complaints.
  • During this time, two teaching assistants (TAs) standby in the room, awaiting instructions. These TAs are the hands of the student technologist.
  • The student technologist instructs the TAs on positioning of the X-ray table and X-ray machine. The TAs quickly follow the exact instructions of the student technologist and are not allowed to make their own adjustments.
  • The student technologist then asks the patient to lie on the X-ray table and provides verbal details to the patient on how to align their body.
  • The student technologist conveys last minute adjustments to the TAs and the X-rays are taken.
  • Carson then uses this to grade the exam.

While Carson increased the test grade required to pass the test from 75 percent to 85 percent, his students still passed with flying colors and many students completed the test within eight minutes of the allotted 12-minute maximum. He explains the situation with the following analogy: “Strap a GoPro® to the front of a car. Get in the back seat with a laptop watching the GoPro footage. Have someone drive without crashing into anything by following verbal instructions from the person in the back seat.”

Mammography lab virtual instructionThe use of the cameras was also not a one-time thing. In her Mammography labs, department chair Debbie McCollam used the same setup to teach her junior students. Students instructed professor McCollam on how to position their Mammography phantom, “Bertha,” and instructed her as the technologist on hand position, where she needed to stand, how she needed to instruct the patient, machine operations, technique selection on the control panel, and computer set up.

Students in McCollam’s course performed a second practical via this system, which focused on Quality Control procedures. The same process was implemented, instructing her as the technologist on how to set up the procedure on the computer, the Mammography unit, and the control panel for the technique. “Mammography is a difficult topic to teach without hands-on experience as proper positioning is completely reliant on the patient’s body position, relaxation of the patient’s pectoral muscle, and technologist hand placement,” shared McCollam. “I truly had no idea how this would turn out, but figured it was worth a try. I was thoroughly impressed how the students stepped up to the challenge and completed the task magnificently!”

A technician in Oregon Tech’s information technology department, Hayes explains that the project was a collaborative effort, which included help from the university’s Manufacturing & Mechanical Engineering and Technology (MMET) department to create the custom solution Carson was looking for. “When Richard approached me for this project there were a lot of parameters that the design had to accommodate,” Hayes said. “Top items of this list are simplicity, portability and image quality. Nobody offered exactly what we needed, so I looked in-house to design and make it.” Hayes reached out to Phil Dussel in MMET to help with design and mechanical needs for integrating the technology into a physical product. “Phil was able to build upon the features provided by the manufacturer and create custom mechanical components to allow me to build a truly integrated solution.”

As sophomores, students in the course who passed Carson’s exam—which in this case was all students—will still rejoin the program in the Fall and take the exam in-person to comply with American Registry of Radiologic Technologists standards and requirements, but they continue to move forward in their courses and are not a term behind due to the unforeseen COVID-19 circumstances.

Watching Carson’s exam, one thing becomes readily apparent: there is limited to no physical contact between the patient and TAs. While all instructions are provided verbally by the student technologist, the future radiologic technologists are quickly learning how important verbal instructions are and how to clearly communicate with patients. McCollam also discovered this during her courses and plans to integrate additional training on verbal instructions into her future classes. She shared, “I found that when the students took the time to organize their thoughts and find the right technical terms to describe the steps to the procedure, they had a much greater understanding of how to correct problems when they occurred. In the future, I will incorporate more verbal description training along with physical positioning.”

Carson plans to keep the virtual system in place for future use, integrating it into his courses and he has also had discussions about the possibilities the system presents. “With this system or one like it, it could be integrated into a portable X-ray system that could have applications for developing nations,” said Carson. “I’m looking forward to bringing this system into courses in the future. I cannot thank ITS and Scotty enough for their help with this system and for ensuring that students in my program did not fall behind in their coursework.”

McCollam agrees that the camera system proved to be a very effective method of teaching. “Our motto has always been, ‘see one, do one, teach one,’” she shared. “The cameras allowed for that during a very critical time. Students were able to watch me do a procedure in a video recording, practice in their homes with whatever they had to work with, and solidify their knowledge by teaching me, as the technologist, in how to properly perform a Mammogram and a Quality Control procedure. I was thoroughly impressed with the results.”
