First Claim
Patent Images
1. A method for processing a computed tomography image comprising the steps of:
- obtaining a computed tomography image of a lung of a subject with contrast agent administered to the subject so as to affect said image, said image being comprised of pixels each having a Houndsfield Unit (HU) value associated therewith and each having a gray scale associated therewith dependent on the HU value thereof;
determining pixels representing pulmonary parenchyma in said image, as pulmonary parenchyma pixels; and
generating a processed image by presenting all of said pulmonary parenchyma pixels in false colors respectively corresponding to different HU values, and presenting remaining pixels in said image in said gray scale values.

Abstract
In a method and apparatus for image processing proceeding from a computed tomography (CT) image of a lung as an original image that is registered using a contrast agent, pulmonary parenchyma pixels are determined, the pulmonary parenchyma pixels are presented in false colors, and the remaining image regions are presented in the gray scale values of the original image.

18. A computed tomography apparatus for processing a computed tomography image comprising:
-
a scanner with a contrast agent injector for obtaining a computed tomography image of a lung of a subject with contrast agent administered to the subject so as to effect said image, said image being comprised of pixels each having a Houndfield Unit (HU) value associated therewith and each having a gray scale associated therewith dependent on the HU value thereof; a processor for determining pixels representing pulmonary parenchyma in said image, as pulmonary parenchyma pixels; a display connected to said processor; and said processor generating a processed image wherein all of said pulmonary parenchyma pixels are presented in false colors respectively corresponding to different HU values, and remaining pixels in said image are presented in said gray scale values and causing said processed image to be displayed at said display. - View Dependent Claims (19, 20)

21. A workstation for processing a computed tomography image of a lung of a subject with contrast agent administered to the subject so as to affect said image, said image being comprised of pixels each having a Houndfield Unit (HU) value associated therewith and each having a gray scale value associated therewith dependent on the HU value thereof, said workstation comprising:
-
a processor for determining pixels representing pulmonary parenchyma in said image, as pulmonary parenchyma pixels; a display connected to said processor; and said processor generating a processed image wherein all of said pulmonary parenchyma pixels are presented in false colors respectively corresponding to different HU values, and remaining pixels in said image are presented in said gray scale values, and said processor causing said processed image to be displayed on said display. - View Dependent Claims (22, 23)
