C-ARM COMPUTERIZED TOMOGRAPHY SYSTEM |
摘要 |
<p>A system and method for generating CT-type three dimensional imaging information from a conventional C-arm fluoroscope system. This enables the adaptation of widely used C-arm installations to provide CT-type information. The system uses a three dimensional target disposing in a fixed position relative to the subject, and obtains a sequence of video images of a region of interest of a subject while the C-arm is moved manually or by a scanning motor. Images from the video sequence are analyzed to determine the pose of the C-arm relative to the subject by analysis of the image patterns of the target. Images are selected from the video sequence according to predetermined criteria. A set of two-dimensional image data with associated positional data is obtained, which is used to reconstruct a three dimensional volumetric set of imaging data of the region of interest of the subject.</p> |
