Method and system for determining respiratory particle deposition in a lung
A recently filed patent (Publication Number: US20230306166A1) describes a computer-implemented method and system for simulating respiratory particle delivery to the lungs. The method involves generating a single conduit model that represents different generations of the lung, with each generation having at most two branches. A computational fluid dynamics (CFD) simulation is performed to determine the mass of respiratory particles leaving one generation and the mass of particles deposited in the next generation. Based on this data, a total mass of respiratory particles deposited in a specific generation of the lung is determined using a scaling factor.
The patent also describes the inclusion of additional CFD simulations to determine the total masses of respiratory particles deposited in the lung for a range of input parameters. This data is then used to generate a reduced order model (ROM) that can predict the total masses of respiratory particles deposited in the lung. The number of additional CFD simulations is based on the range of the input parameter, which can include factors such as total particle mass or total air volume entering a specific generation of the lung.
The patent further details a computer-implemented method and system for performing the above-described simulation. The method involves receiving a single conduit model representing different generations of the lung and performing a CFD simulation to determine the mass of respiratory particles leaving one generation and the mass of particles deposited in the next generation. A scaling factor is then used to determine the total mass of respiratory particles deposited in a specific generation of the lung.
The system described in the patent includes a memory to store the conduit model and one or more processors to perform the CFD simulation and determine the total mass of respiratory particles deposited in the lung. The processors can also perform additional CFD simulations to determine the total masses of respiratory particles deposited in the lung for a range of input parameters and generate a reduced order model for predicting these masses.
In summary, the patent describes a method and system for simulating respiratory particle delivery to the lungs using a single conduit model and computational fluid dynamics. The invention allows for the determination of total masses of respiratory particles deposited in different generations of the lung and the generation of a reduced order model for predicting these masses based on input parameters.
