Systems and methods for simulation-based radiation estimation and protection for medical procedures

摘要

Systems and methods for determining radiation exposure during an x-ray guided medical procedure are disclosed. In some embodiments, the system includes an x-ray equipment model that simulates the emission of radiation from x-ray equipment during the x-ray guided medical procedure, a human exposure model that simulates one or more human anatomies during the x-ray guided medical procedure, a radiation metric processor that calculates at least one radiation exposure metric, and a feedback system for outputting information based on the at least one radiation exposure metric. The radiation metric processor calculates radiation exposure metrics based on input parameters that correspond to operating settings as well as the location and structure of one or more human anatomies.

1. A system for determining an amount of radiation exposure to one or more humans during a simulated x-ray guided medical procedure without exposing a human to ionizing radiation, the system comprising:
an x-ray equipment model that simulates the emission of radiation from x-ray equipment during the x-ray guided medical procedure without emitting ionizing radiation, the x-ray equipment model comprising a first set of input parameters corresponding to operating settings controlled during the x-ray guided medical procedure,
wherein the input parameters are configured to vary during the simulated x-ray guided medical procedure; a human exposure model that simulates one or more human anatomies during the x-ray guided medical procedure, the human exposure model comprising a second set of input parameters corresponding to the location and structure of one or more human anatomies during the x-ray guided medical procedure; a radiation metric processor that calculates at least one radiation exposure metric to one or more humans located in a room of the simulated x-ray guided medical procedure,
wherein the calculation of the radiation exposure metric occurs during the x-ray guided medical procedure, and is based on the first set and second set of input parameters and a model that associates a change in the first set and second set of input parameters with a change in the radiation exposure metric; a feedback system for outputting information based on the at least one radiation exposure metric during the x-ray guided medical procedure,
wherein the feedback system further comprises an x-ray imaging simulator for displaying x-ray images of the human based on the x-ray equipment model and the human exposure model, and wherein said x-ray imaging simulator displays a sequence of x-ray images and in response to the variations of the first and second sets of input parameters; and an endovascular simulator that tracks the motion of a medical instrument, and translates the detected motion into movements of virtual instruments inside the human exposure model.
