| 发明名称 | Systems and methods for performing truncation artifact correction | ||
| 摘要 | A method for performing truncation artifact correction includes acquiring a projection dataset of a patient, the projection dataset including measured data and truncated data, generating an initial estimate of a boundary between the measured data and the truncated data, using the measured data to revise the initial estimate of the boundary, estimating the truncated data using the revised estimate of the boundary, and using the measured data and the estimated truncated data to generate an image of the patient. | ||

| 主权项 | 1. A method for performing truncation artifact correction, said method comprising: acquiring a projection dataset of a patient, the projection dataset including measured data and truncated data; combining forward projected truncated data and the measured data to generate a revised dataset; reconstructing at least one image using the revised dataset; classifying the reconstruction into either water or air to generate generating an initial estimate of a location of a boundary between the patient and air using the measured data and the truncated data; using the measured data to revise the initial estimate of the location of the boundary; estimating the truncated data using the revised estimate of the location of the boundary; and using the measured data and the estimated truncated data to generate an image of the patient. | ||
