Data Visualization in Medical & Healthcare Applications

Medical-Data-Visualization-MedTech-Applications

The fact that data and data visualization are everywhere in today's world, makes me wonder how data visualization impacts medical applications and what's their role within patients' diagnoses? Undoubtedly, patients trust their wellness on healthcare professionals' criteria and decisions but what do doctors, nurses, practitioners, and other healthcare professionals base their judgment and decisions on?

The experience factor indeed drives medical decisions but when talking about complex medical diagnoses, healthcare professionals need to base their decisions and judgments on accurate information coming from different sources such as laboratory analyses made by experts (e.g., medical technologists) who are constantly involved in working with medical observations, samples, data, test results, researches, etc. 

For professionals working in the health sector and treating hundreds of patients a year, it is key to trust reliable and accurate data, but how does data visualization impact the medical sector?

Key Takeaways

  1. The Healthcare industry is one of the industries that generates the most data every year. In 2020, it was estimated that this sector created around 2,314 exabytes of data.
  2. High-performance medical applications benefit from data visualization to visualize large datasets and support more accurate decision-making processes including diseases treatments and diagnoses.
  3. Visualizations featured in MedTech and Healthcare applications demand the highest performance charting components.

Why is Data Visualization Important in MedTech and Healthcare?

We've all seen at least one popular TV show or movie that showcases an example of a medical application that monitors a patient's e.g., heart rate, that looks like this:

Electrocardiogram-Data-Visualization-JavaScriptExample of an Electrocardiogram (ECG)

So, even for non-medical readers, it becomes more intuitive to get the idea of a heartbeat visualization. But what would happen if you'd have to visualize the (sample) dataset instead? Let's take a look at a sample dataset of a heart rate contained in a spreadsheet:

Sample dataset of an ECG_2

The image above is a sample dataset containing hundreds of data points that at the bare eye, is tedious to understand even for medical professionals. In that case, how is data visualization used in healthcare? Data visualization helps in the process of transforming and visually displaying medical data points that simplify and synthesize the analysis of complex and large datasets into visualizations that are easier to process, visualize, and understand. 

With that being said, data visualization and healthcare imaging offer another way how to understand data even for non-technical readers. Nowadays, medical applications that help users to track basic medical information are more common and can be found on people's smartphones and smartwatches.

So, it wouldn't be useful for users to visualize spreadsheets on their smart devices but rather translate complex data into simpler visualizations. After this concept, it is easier to understand why medical visualization plays a key role in the medical sector.

According to Statista, the amount of healthcare data generated in 2013 was 153 exabytes (where 1 exabyte equivalents to 1 billion gigabytes) and by the end of 2020, it had already increased to the colossal amount of 2,314 exabytes.

With the upward trend of the development of more medical monitoring applications for organizations and individuals, the amount of data that will need to be visualized, analyzed, and explored will indeed continue to grow rapidly in the upcoming years. 

The continuous growth of medical data is a key driver for health organizations that are trying to provide a better and more personal patient-centric health service. As a consequence of this, data analytics, big data, and data visualization are becoming important subjects in healthcare that are helping to prevent and predict diseases.

The analysis of data represents a tremendous opportunity for health specialists to make data-driven decisions based on historical information that is later presented in state-of-the-art applications featuring the most advanced data visualization technology.

Preventive & Predictive Medical Visualization

While the future cannot be predicted, certain branches of data analytics in medical technology are present in the healthcare sector in order to convey different analyses that help professionals to work with past and future diagnoses. That is the case of descriptive analytics that takes a look into the performance of historical data and its behavior and relevance in the matter, e.g, in diagnoses.

The diagnostic analysis aims to understand why certain diseases occur and to explain their root causes whereas predictive analysis aims to forecast and anticipate future diagnoses and diseases which, therefore, acts as a method of prevention. Finally, the prescriptive analysis aims to test multiple scenarios to anticipate the outcomes before a final decision is made by a health professional.

The importance of data-related subjects such as data visualization is not only for health monitoring but also helps medical professionals to step ahead into possible future diseases and explain the triggers of past illnesses and harmful conditions. 

Here's an example of a 3D volume rendering visualization of a skull that involves thousands of data points and is commonly used for studies in anatomy, traumatology, implants design, craniofacial reconstruction,  or surgery analysis and planning, among other applications.

What is Medical Data Visualization?

As earlier mentioned, the volumes of data are steadily increasing in the healthcare sector and more medical professionals continue to experience difficulties when trying to make sense of patients' health information.

Within the different areas of data, data visualization specializes in transforming complex healthcare data and analyses into visual formats that help medical decision-making professionals to formulate diagnoses and treatments for patients in order to deliver effective medical care.

High-quality visualizations have been determined to be key in improving how health professionals perform decision-making processes and identify patients' health trends to understand future conditions (predictive analysis) and diseases. 

Technically, medical data visualization refers to increasing the efficiency and accuracy when reviewing and observing data for instance when visualizing organs, bone elements, or diseases processes. So, the process of medical or advanced data visualization helps to merge information from multiple sources that would otherwise stand alone and could not be related.

An excellent example of this was made by researchers Jonathan Wanderer, Jesse Ehrenfeld, and Soojin Park who stated:

"A visualization made for evaluating a kidney injury could merge multiple data from sources such as urine, urine electrolytes, serum creatinine, and blood pressure allowing doctors to quickly review and predict a change in the normal functions of the kidney."

Such visualization can be later used to understand and explore the disease, discuss the condition with other medical experts, and present the diagnoses to the patient's family.

Data Analytics & Data Visualization Applications in Healthcare

Almost all the areas of healthcare and medicine can apply data analytics including data visualization. Today, modern medicine continuously uses data to provide a patient-centered approach and a more customized healthcare service. Moreover, data visualization in health IT is driving professionals to better decision-making processes. 

Several areas of medicine have been improved and benefited from 3D models, e.g., x-rays, MRIs, or 3D volume renderings. High-performance visualizations are used within, if not all, the most demanding applications in healthcare, for instance, telesurgery, monitoring, surgical planning, or genomic analyses. 

Molecular Analysis

In molecular analysis, Omics data refers to data sources from molecular fields where data is used with the aiming of understanding how diseases develop and how to improve the diagnoses of medical treatments.

Common visualizations used in this field are so-called N-body simulations that simulate the behavior of particles within environments, e.g., the human body system.

Genomics

Genomics refers to the study of genes and their functionalities which is key for researchers and medical experts when studying the prevention and cure of certain diseases. Visualizing data is key for observing and analyzing the correlation and trends that exist within large data sets that would otherwise be more complicated to analyze.

Medical Device Development

Data visualizations are commonly and widely adopted in medical devices for, e.g., cardiac rhythm monitoring, cardiovascular devices, diabetes monitoring, and prevention, etc.

Charts & Graphs Used in Healthcare Visualization

Charts and graphs plot the data with respect to different axes creating specific forms or visualizations.  As mentioned before, the amount of healthcare data is enormous and continuously growing thus demanding visualizations to be able to render a great number of data points at high-performance characteristics.

The requirements of the visualizations will be driven by the clinical needs but some of the characteristics of the highest performing visualizations would include:

  • Powerful data visualization libraries. There are several open-source and commercial libraries written in different languages including JavaScript, Python, or .NET. Depending on their nature, these libraries are designed for basic or advanced data visualization purposes.
  • Rendering performance. Not all libraries are meant to handle advanced medical and healthcare data sources. Open-source libraries experience this problem as they are limited in resources and performance. Commercial libraries are there to solve those issues and can render billions of data points in real-time without performance issues.
  • Resources optimization. Is the healthcare sector prepared to visualize all its data? Certainly, it is preparing for and GPU-accelerated libraries are using the PCs' power to deliver higher-quality visualizations at faster rendering and response times. 

Here are 3 examples of advanced visualizations that can be later integrated into medical applications:
