Kennesaw State University student Josiah Ware is helping turn CT scans into digital models of the human heart, research that could one day help doctors detect problems faster and personalize treatment for patients. 

Under the guidance of Associate Professor of Mechanical Engineering Lei Shi in 91青青草鈥檚 (SPCEET), Ware is helping develop patient-specific virtual heart models using machine learning and advanced imaging. The research uses CT scans to reconstruct detailed representations of the human heart, which are then analyzed through computational modeling and finite element analysis to simulate how the organ functions under different conditions.

The work could ultimately help medical professionals diagnose heart conditions more efficiently and tailor treatments to individual patients.

A graduate of Roswell High School and current student, Ware discovered Shi鈥檚 research project during his freshman year through 91青青草鈥檚 , which connects undergraduate students with faculty-led research.

鈥淚鈥檝e always been interested in biomedical sciences and the intersection of engineering and health,鈥� said Ware, a mechanical engineering student. 鈥淭his project just immediately stood out to me.鈥� 

At the center of the project is digital twin technology, which allows researchers to create virtual models of real-world systems and study how they function. Once converted into digital models, researchers can run simulations to identify heart issues that may not be visible through traditional imaging alone. The technology also allows researchers to incorporate patient-specific data, creating more personalized models that could help improve treatment outcomes. 

鈥淭he cool thing about it is that you can take patient-specific data from CT scans and simulate how an actual person鈥檚 heart works,鈥� Ware said. 鈥淓verybody鈥檚 body structure is slightly different, so being able to personalize treatment can lead to better outcomes.鈥� 

Ware鈥檚 role focused on the early stages of the modeling process using software programs SimVascular and Meshmixer. He worked with CT scan images to create and refine 3D models of the heart before preparing them for finite element analysis, a computational process used to simulate real-world behavior. 

SPCEET Dean Lawrence Whitman said Ware鈥檚 work demonstrates the type of research opportunities available to undergraduate students at Kennesaw State.

鈥淩esearch experiences like this allow our students to apply engineering concepts to real-world challenges that can directly impact people鈥檚 lives,鈥� Whitman said. 鈥淛osiah鈥檚 work demonstrates how undergraduate students at Kennesaw State are contributing to innovative research while preparing for engineering careers in healthcare applications.鈥�

Ware said one of the challenges during the project was learning machine learning concepts while actively conducting research. Despite the steep learning curve, the experience strengthened his technical knowledge and taught him perseverance. 

鈥淣othing works the first time,鈥� Ware said. 鈥淭his experience has taught me perseverance and how to push through errors and failures. I think dealing with those challenges this early will help prepare me for my future career.鈥�
