Abstract:
1. A computed axial tomography scan normalization system comprising: an acquisition interface configured to access from an electronic database computed axial tomography data of a head region of a patient, the computed axial tomography data comprising a volumetric data set of the head region; a skull segmentation filter configured to identify a skull region in the volumetric data set and an intracranial region in the volumetric data set; an atlas alignment engine configured to access from an atlas database a normative data set based on a computed axial tomography scanner type; a registration generator configured to apply an image registration algorithm to generate alignment data, and to align the volumetric data set to the normative data set to generate an aligned volumetric data set using the alignment data; a ventricle segmentation filter configured to identify anterior and posterior portions of ventricular regions of the patient in the aligned volumetric data set; a reslicing generator configured to reslice the aligned volumetric data set to generate a normalized volumetric data set; and an output interface configured to output the alignment data to a picture archiving and communication system or to output the normalized volumetric data set and a visualization corresponding to the anterior and posterior ventricular regions of the patient, wherein the computed axial tomography scan normalization system comprises a computer processor and electronic storage medium.
