Initializing model-based interpretations of digital radiographs
First Claim
1. A method for obtaining initial model parameters for a model-based interpretation of a digital radiograph obtained from a patient in accordance with a radiographic protocol, wherein the model-based interpretation changes the model parameters based on content of the digital radiograph so as to model features therein, said method comprising:
- identifying a region of interest in the radiograph, wherein the region of interest is identified based on landmarks common to multiple different radiographs obtained with the same radiographic protocol; and
analyzing the region of interest so as to calculate one or more candidates for initial model parameters.

Abstract
Automated computer aided diagnosis (CAD) processing of digital radiographs through model-based interpretation, with the initialization providing a set of initial parameters used by the model. The initial parameters can be selected based on expected pathology in the digital radiograph, and are optimized by the model to match features shown in the radiograph. The model can be an iterative model or a non-iterative model. Analysis is performed on the interpretation result, so as to diagnose pathology shown in the radiograph.
