Abstract

The invention discloses a tubular structure length measurement system and method based on a three-dimensional medical image. According to the measurement system and method, by the adoption of the differential summation principle in mathematics, length value calculation of a tubular structure is converted into cumulative calculation of distances between a series of adjacent slices, wherein first, acenter line of the tubular structure is extracted; second, a normal plane is constructed based on the center line, the tubular structure is subdivided into a series of two-dimensional sections, and the range of a region-of-interest is determined on an image subjected to straightened surface reconstruction; and last, the sum of wall distances, between the adjacent sections contained in the region-of-interest, of the tubular structure is calculated, and a needed length value of the tubular structure is obtained. Therefore, precise measurement of the length of the tubular structure is realized,and the measurement system and method can be widely applied to the fields of intravascular stent preoperative planning, plaque length measurement, thrombus length measurement, angioma and interlayer measurement, intestinal polypus measurement, etc.

Description

technical field [0001] The invention belongs to the technical field of medical image processing, and relates to a method for measuring the length of a tubular structure, in particular to a system and method for measuring the length of a tubular structure based on a three-dimensional medical image. Background technique [0002] With the help of modern medical methods such as magnetic resonance (MRI), computed tomography (CT), ultrasound (US), digital radiography (DR), optical coherence tomography (OCT) and virtual colonoscopy technology, etc., it can provide multimodal The state of the human heart and brain blood vessels, digestive tract and other lumen cavity or wall (hereinafter collectively referred to as tubular structure) information. In view of the complex geometry of the tubular structure in three-dimensional space, such as bending, coiling, etc., the current length measurement scheme that only considers the straight-line distance of the region of interest of the tubul...
