Methods, devices, systems and apparatus for determining emphysema thresholds for processing a pulmonary medical image are provided. In one aspect, a method includes: determining lung lobe regions in the pulmonary medical image, and, for each of the lung lobe regions, clustering CT values in the lung lobe region to divide the lung lobe region into a first sub region and a second sub region and acquiring a CT value corresponding to an intersection of a first CT value distribution function for the first sub region and a second CT value distribution function for the second sub region in the lung lobe region as an emphysema threshold for the lung lobe region.

Image processing and emphysema threshold determination

The present invention discloses apparatus, method, and system for CT image processing; said apparatus comprises: an interface unit for obtaining CT images; a target region separation unit for separating said target region from the CT images by means of judging the CT values of voxel points in said CT images, wherein points with CT values greater than or equal to the threshold for target region separation constitute the target region, and said target region comprises at least one separate region; a false positive region removing unit for removing false positive regions from said target region and obtaining the accurate target region. The present invention can be used to quickly and conveniently determine the target region to be detected, measure the characteristic data of the target region, and display the physical and relative positions of the target region in a three-dimensional manner; with a lower threshold for target region separation, the present invention can reduce the omission rate of detection; in addition, on that base, the present invention can remove possible false positive regions, thereby describing the target region accurately and improve accuracy of target information.

Apparatus, method and system for computer tomography image processing

The present invention discloses an abdominal CT image measuring apparatus and method. The abdominal CT image measuring apparatus includes: an interface unit; a part recognizing unit and a characteristic data computing unit. The present invention can determine the specific region of the part under test with a little amount of computation, by registration and subtraction operation on the two-phase scan images. This is easy to be carried out in computers, thus the computing speed of the characteristic data can be guaranteed and the efficiency can be improved. By the recognizing of the kidney regions and the abdominal aorta region in the present invention, the glomerular filtration rates obtained by applying the key concept of the present invention to the image measuring of glomerular filtration rate can meet the clinical application requirements in both precision and speed.
