Building a personalized heart simulation

43:56is create a digital twin, a personalized 3D computer simulation of the patient's heart. Okay, here's how they do it. They first take a bunch of really highresolution MRI scans and they create a 3D digital twin of the patient's heart. So, every patient gets his or her own digital twin. Okay? Then what you do is you reconstruct that in your software. Okay? All of those 2D images from the MRI scans become this 3D really high resolution image and then you simulate what is happening in that heart because now you know enough about heart cardiology, about heart physiology,

44:37about how these neurons are working and the model is then assigned these electrical properties and this the the researchers pace that digital heart in the same way that the pacemaker cells create this electrical gradient that causes the heart to contract and then and then you know push out blood to the lungs, take in blood from the lungs, so on and so forth. And what you can do here is you can do a virtual surgery. So here here's what's happening in in the video. Okay, >> that's fascinating. >> So you've got you've got the heart. You've got you've created this 3D model. Now you're simulating the electrical signals in that heart and you're trying to figure out where just according to

45:19the physiology of the heart there should
