Automatic Correction And Reformation Algorithm Of CT Brain Image

Computerized Tomography(CT) technology is an indispensable and important means in medical imaging technologies today.Traditional CT imaging brain images have several drawbacks.In order to achieve the observation of the organizational structure better,medical expert put forward a new way of CT brain images show.However,the display of the new way needs adjusting manually by doctors, to a large extent depending on the medical staff of a priori knowledge and clinical experience.This observation for the diagnosis of medical staff has a great deal of inconvenience.So this paper put forward an automatic algorithm,which realize the automation of CT brain image processing,and for the clinical diagnosis of the human body,it will provide a true visual reflection of the structure of medical images for medical personnel and observation of the lesions for surgery.In this paper,we bring forward an automated three-step method of CT brain image processing:1.Pre-treatment using the homomorphic filtering of CT brain image processing to enhance contrast,and then according to the symmetry of the brain to carry out a preliminary calibration of the image.2.In this thesis,according to the correction of the original image based on the brain axial images,we get the sagittal reconstruction mages and coronal reconstruction mages of the brain.3.We extract the direction of the hard palate from mid-sagittal image and then though the image optimized processing under the new requirements of the medical images,we can display a new standard CT brain image.In this paper,homomorphic filtering pre-processing and the largest value of related combination of automated image correction;at the same time,based on medical research and analysis,combined with the characteristics of the brain images,we achieve the standardization of medical images on computer automation.After the automated method of brain CT image processing,the brain images have a standardization of the reconstruction and the optimized images have significant effect.The new CT brain image display improved the accuracy of medical diagnosis.
