Cardiac TEE Rendering × 5D Viewer

Overview

Leading rendering and UI optimization for the 5D Viewer in Samsung Medison’s cardiac transesophageal echocardiography (TEE) product. The 5D Viewer renders live volumetric ultrasound data of a beating heart, reconstructed directly from real-time data transmitted by the transducer. That combination — volumetric, live, and medical-grade — makes performance a hard constraint rather than a nice-to-have: clinicians need the rendered volume to respond immediately as they adjust the probe and the view. The 5D Viewer also serves as the testbed for our rendering engine’s capability more broadly.

The project centers on rendering different types of GDI objects onto both static and real-time 3D volumes, and aligning operations on the 2D plane cut from different locations within the 3D volume.

What I work on

Rendering and interaction

• Optimizing the UI design of the viewer for responsiveness under continuous volume updates
• Implementing the interaction layer that handles actions performed on rendered objects — rotation, slicing, and repositioning within the volume
• Sole owner of optimizing the 5D Viewer UI

Internationalization

• Implementing support for rendering labels in all languages worldwide

4D Markers and Calipers

• Designing and implementing 4D markers — points placed within the volume to indicate different conditions
• Designing and implementing 4D calipers — similar to markers, but used to indicate covered area using different shapes: lines, angles, polygons, and splines (both closed and open)
• For both features: built using DirectX, spanning the UI component, the communication pipeline between the rendering engine and the UI, the backend implementation for rendering the shapes, and testing on the ultrasound machine itself
