What Is Computer Vision and How Is It Being Used in Healthcare?

Computer vision artificial intelligence can improve patient care, but reaping its full benefits relies on careful training, data protection and validation by medical professionals.

Computer vision is a type of artificial intelligence designed to replicate the way humans see and understand the world around them. The AI camera takes in visual information, and the algorithm processes the data and learns from it to perform tasks.

The use of computer vision in healthcare is expected to grow quickly over the next decade. The global market value is projected to increase from $2.6 billion in 2024 to more than $53 billion by 2034, according to Precedence Research.

Like all AI, computer vision is only as reliable as the information that feeds it, so organizations need to prioritize data quality and testing to ensure accuracy. However, if utilized strategically, experts say computer vision could significantly advance care quality and help solve long-running challenges such as growing patient demand and staff shortages.

“Sight is our most powerful sensory capability, with up to 90% of our brains directly or indirectly participating in the processing of visual information. Similarly, computer vision is the most valuable form of AI-enabled perception,” says Dr. Andrew Gostine, CEO of Artisight and a critical care anesthesiologist. “High-bandwidth image processing with computer vision is the only way to drive healthcare automation at the scale required to fix many of healthcare’s access and efficiency problems.”

What Is Computer Vision in Healthcare?

Computer vision AI is designed to interpret and react to situations much like a doctor, nurse or scientist would. The technology has the potential to improve patient monitoring, allow providers to diagnose diseases much earlier, and help make surgeries more precise.

Computer vision AI also has the potential to reduce errors because unlike humans, computers don’t blink and or get tired. “It’s important to recognize these tools aren’t magic wands or silver bullets,” cautions Dr. Christopher Longhurst, chief clinical and innovation officer at UC San Diego Health and executive director of the Jacobs Center for Health Innovation. “They only deliver outcomes when people use them effectively in workflows to deliver better patient care.”   

Key Use Cases of Computer Vision in Healthcare

There are many different ways computer vision AI is being implemented in healthcare.

Medical Images and Diagnostics

Radiology departments have adopted computer vision AI to help providers analyze medical images and detect anomalies sooner, which allows for better patient outcomes.

Longhurst says this technology helped UC San Diego Health identify COVID-19 pneumonia during the pandemic. He gives an example of a heart failure patient who didn’t yet have respiratory symptoms, but a chest x-ray highlighted a potential infection and prompted the medical team to run a COVID-19 test. “The AI helped make the diagnosis much earlier, and the patient was treated and went home without needing critical care.”

He says UC San Diego Health also uses computer vision AI to help prioritize high-risk exams. “The AI can find the patient who potentially had a previously undiagnosed stroke and bring that to the top of the radiologist’s work list,” explains Longhurst.

Surgical Precision and Assistance 

AI cameras are assisting surgeons with minimally invasive laparoscopic and robotic procedures. The technology helps identify critical anatomy and tracks the movement of the surgical tools. In addition, Longhurst says machine vision AI is used to verify that all materials, such as sponges, have been removed from the patient’s body before closing the incision.

Computer vision AI is also creating opportunities to expand access to highly specialized care anywhere in the country. Gostine says that cameras can allow specialists to participate remotely in complex surgeries.

“We put the hardware in the operating room and stream the video and audio feeds to a control desk. This reduces friction in communication,” says Gostine. “We then turn on the computer vision algorithms to drive data capture for use cases ranging from OR efficiency and waste reductions to quality improvement and patient safety.”

Real-Time Monitoring

Humans have only one set of eyes and can’t be everywhere at once, but an AI camera can fill in the gaps. Computer vision AI can help improve patient monitoring and reduce preventable issues such as falls — which, according to the Centers for Disease Control and Prevention, annually costs the healthcare system up to $50 billion.

One example of this technology is Artisight’s Patient Room solution. One of its features is that it can send automated alerts when it detects that a patient is trying to get out of bed. A virtual nurse can talk to the patient via a two-way enabled feed, and an alarm can alert nearby staff to the room. As the AI learns, it should better predict patients’ conditions.

“As a physician, I can maximally treat maybe 2,000 patients per year, but you can train an algorithm on hundreds of millions of patient encounters,” Gostine says. “It’s an incredible amount of insight built into a camera that costs less than a dollar per day.”

Considerations for Implementing Computer Vision in Healthcare

When implementing computer vision AI, healthcare organizations should use the technology to help existing workflows operate more efficiently. “Tools that are workflow-integrated usually perform the best,” says Longhurst. “That may mean integrating with the electronic health record, or with the PAC system for radiology imaging.”

Another critical consideration centers on how the AI algorithm is trained. When teaching the AI how to respond to patient scenarios, Gostine argues simulations don’t go far enough because they “don’t fully replicate the actual hospital environment.” He explains that by training computer vision AI in a real hospital, the system learns how to better work alongside doctors and nurses in live clinical environments.

Gostine adds that training algorithms in a live clinical environment involves extra considerations for patient privacy. “We developed a proprietary technique for training algorithms using synthetic data that exceeds the privacy standards defined by HIPAA for de-identifying patient data,” he explains.

The Future of Computer Vision in Healthcare

Gostine expresses optimism that computer vision AI will become significantly more useful and powerful in the near future. “Over the next eight years or less, we’ll have another one-thousand-fold increase in the intelligence of these algorithms as the amount of compute rises,” he says, predicting that “computer vision is going to be the general-purpose sensor for almost every aspect of health care.” 

Longhurst forecasts increased use of AI in healthcare for diagnostic purposes. He expects that specialties such as ophthalmology and dermatology will benefit significantly from computer vision AI.

“I think AI will have a bigger impact on healthcare than anything we’ve seen since antibiotics, but there needs to be more testing to measure outcomes and determine how the technology works in different environments,” Longhurst says. “Even if we’re using computer vision AI as clinical decision support, ultimately hospitals and doctors are still accountable for delivering standard of care.”
