Determining cross-sectional areas of fluid passageway in anatomy
A recently granted patent (Publication Number: US11969219B2) discloses a computer-implemented method for determining information about the cross-sectional areas of a passageway in anatomy for fluid flow. The method involves obtaining a 3-D model of the passageway, placing a representation of a prosthetic device within the model, and creating section planes by rotating a starting plane. These section planes help calculate cross-sectional areas, allowing for the identification of maximum or minimum areas, which are then compared to a threshold to facilitate the selection of an appropriate prosthetic device based on the comparison.
Specifically designed for applications in the left ventricular outflow tract (LVOT), the method utilizes a 3-D model of a prosthetic mitral valve to determine neo-LVOT areas. By incorporating multiple starting planes and axes for rotation, the method ensures a comprehensive analysis of the passageway's cross-sectional areas. Additionally, the patent covers the implementation of the method on a computing device, where a processor performs operations involving obtaining the 3-D model, calculating cross-sectional areas, and facilitating the selection of a prosthetic device based on the comparison of maximum or minimum areas to a predefined threshold. This innovative approach offers a systematic and efficient way to assess passageway anatomy for fluid flow applications, particularly in the context of prosthetic device selection and placement.
