Abstract

The invention proposes a technique that simplifies, accelerates and automates partitioning of multi-lobe organs while maintaining consistency (pre-condition) during related clinical workflow. The technique includes a workflow or framework of the editing which is a part of a general clinical image processing workflow. The organ is a disjoint set of partitions. Clinician reviews the organ partitions on the monitor. If the user is not satisfied with the current partitioning, the user manually corrects the contour of one or more partitions. The user manually edits the contour of the selected partition. Once the editing is done, an automatic method corrects all neighboring, unedited partitions in real time which results in a consistent partitioning. The user reviews the result (contours) of the corrected partitions. If the user is not satisfied with the partitioning, the user starts editing another partition or partitions.

ADAPTIVE PARTITIONED ORGAN EDITING FOR MEDICAL IMAGES

FIELD OF INVENTION

The invention generally relates to multi-lobe organs and more particularly to a technique for editing partitioning of multi-lobe organs.

BACKGROUND OF THE INVENTION

A multi-lobe organ, such as, liver or lungs includes disjoint set of partitions. A pre-condition for multi-lobe organs is that they are union of pairwise non-overlapping partitions. If the initial relationship (pre-condition) of the partitions and associated organs are preserved for an entire workflow, editing of such partitions is very complex and time consuming. The pre-condition is not satisfied if the editing results in a partition which overlaps with any other partition associated to the same organ or a partition which exceeds border of associated organ or one or more gaps between partitions associated to the same organ. Either of the conditions mentioned results in an unwanted state and therefore, results in wrong visualization and/or measure of partitions and the associated organs. The reliability of the visualized contours/partitions from surgical point of view decreases due to inconsistency.

The clinicians are required to delineate contour or a major part of anatomical structures, such as, liver lobes or segments on a large number of two dimensional (2D) or three dimensional (3D) image series in radiation treatment, surgery planning and many other general clinical workflows. There are different techniques known in the art that significantly decrease processing time. However, the techniques have limitations, especially when an organ is required to be partitioned into different segments. The integrity of the organ is damaged. A user is not satisfied with the result of automatic or semi-automatic partitioning method. If the user tries to edit one or more partition manually and if the software is not capable to handle the described issues, incorrect measurements and treatment planning occurs. Moreover, manual correction of damaged contours is either not precise or takes tremendous work if done by user.

Hence there exists a need for an efficient technique to handle hazardous situations during partitioning of multi-lobe organs.
