Medical imaging data is one of the richest sources of information. But, here's the caveat—
Without the right technology in place, doctors are forced to spend hours manually analyzing patient data and doing administrative work.
Luckily, as the years went by and the technology advanced, the healthcare industry had become one of the fastest at adopting new automation solutions, including computer vision.
Let’s explore some of the most popular computer vision applications in healthcare.
In the context of medical X-ray imaging, computer vision can be successfully applied to treatment and research, MRI reconstruction, or surgeries planning.
Although most doctors are still relying on the manual analysis of X-ray images for diagnosing and treating diseases, computer vision can automate the process, increasing both efficiency and accuracy.
State-of-the-art image recognition algorithms can pick up patterns in X-ray images too subtle for the human eye.
Have a look at how V7 handles X-Ray image annotation.
Computer vision is also widely applied in the analysis of CT scans and MRI.
From designing AI systems to analyze radiology images with the same levels of accuracy as human doctors (while reducing the disease detection time) to deep learning algorithms that increase the resolution of MRI images—computer vision is the key to improving patient outcomes.
Here's an example of an ML-assisted brain and spinal cord annotation.
Using computer vision to analyze CT and MRI scans can help doctors to detect tumours, internal bleeding, clogged blood vessels, and other life-threatening conditions. The automation of the process has also proven to increase the accuracy because the machines can now identify details invisible to the human eye.
Image recognition allows doctors to identify anomalies and changes by comparing cancerous and non-cancerous cells in images.
Automated detection allows for a faster cancer diagnosis using data from magnetic resonance imaging (MRI) scans. Computer vision is already successfully applied in breast and skin cancer detection.
Here’s an example of annotated moles that can be analyzed to detect melanoma skin cancer in its early stages.
Postpartum hemorrhaging is one of the biggest causes of mortality in childbirth. Traditionally, physicians could only guess how much blood a patient has lost during childbirth.
Thanks to computer vision, doctors can now measure blood loss during childbirth by using an AI-powered tool to analyze images (taken with an iPad) of surgical sponges and suction canisters.
The Orlando Health Winnie Palmer Hospital for Women and Babies was one of the facilities that implemented this technology. It turned out that in the majority of cases, doctors tend to overestimate the amount of blood lost by patients during child delivery.
Computer vision thus allowed for a more accurate blood loss measurement that helps medical professionals to treat patients more efficiently.
Thanks to the proliferation of whole-slide-imaging (WSI) digital scanners, computer vision can now process medical image data to detect and identify the type of pathology on display.
It is used for:

Computer vision helps to monitor the machinery and equipment to find the maintenance needs and address them proactively before it’s too late.
Computer vision-powered devices monitor incoming data from machinery through cameras that identify defects and other changes. When they detect an issue, they send a signal to the system, allowing human operators to take corrective action before an asset is damaged or an accident occurs.
Large-scale manufacturing sites often struggle to achieve 100% accuracy in defect detection in their manufactured goods.
Camera-based systems can collect real-time data and leverage computer vision and machine learning algorithms to analyze it and benchmark the results against a predefined set of quality standards.
It helps in identifying macro and micro level defects in the production line more efficiently.
This facilitates the error-free production process and decreases costs.
As most products have barcodes on their packaging, a computer vision technique called OCR can be successfully applied to automatically detect, verify, convert and translate barcodes into readable text.
By applying OCR to photographed labels or packaging, the text they contain is extracted and verified against databases.
This procedure helps to identify wrongly labeled products, provide information about expiration dates, inform about product quantity in the magazine, and track packages at all stages of product development.
World-class companies like Tesla have already implemented automation of the product assembly line—the company reported the automation of over 70% of their manufacturing processes.
Computer vision generates 3D modeling designs, guides robots and human workers, identifies and tracks product components, and helps to maintain packaging standards.
NIOSH reports that over 2,000 work-related injuries occur daily in the US alone, which could be prevented through the use of PPE.
Deep learning has enabled the detection of protective equipment in various environments, given that the training data is large enough and representative.
Computer vision is therefore successfully used to ensure proper safety measures and security standards. In case of accidents, the AI-assisted systems help quickly identify and assess the intensity of a given occurrence and respond immediately by taking appropriate measures.
