Embodiment Construction

[0033] The following detailed description is merely exemplary in nature and is not intended to limit the invention or the application and uses of the invention. Furthermore, there is no intention to be bound by any theory presented in the preceding background of the invention or the following detailed description. The intention of this embodiment is to propose an improved computer-aided liver surgery planning system that is easy to use and guarantees a safety margin for the proposed resection.

[0034] figure 1 A flowchart embodying a method of computer-assisted surgical planning according to the present embodiment is depicted. At step 102, a volume is modeled based on a plurality of physical scales. The physical scale of the liver and internal features can be modeled using data from two-dimensional (2D) computed tomography (CT) images. At step 104, a plurality of safety margins are determined around a plurality of features within the volume. For example, features within a...

Abstract

A method for surgical resection planning of a mass is disclosed. The method comprises the steps of, modelling the mass based on a plurality of physical dimensions, determining a plurality of safety margins around a plurality of features within the mass, simulating a resection surface on the mass comprising a plurality of triangles, optimizing local area and position of a first of the plurality of triangles on the resection surface based on a triangle-based algorithm, updating the simulation of the resection surface, and repeating the steps of optimizing and updating for each of the plurality of triangles on the resection surface.

Description

[0001] priority statement [0002] This application claims priority from Singapore Patent Application No. 201304503-4 filed on Jun. 11, 2013. technical field [0003] The present invention relates to computer assisted surgical planning. In particular, the invention relates to computer-aided planning of liver resection surgery. Background technique [0004] The liver is an important organ of the digestive system that performs multiple functions including protein synthesis, hormone production, and glycogen storage. It consists of four lobes of equal size and shape, and is connected to two major blood vessels, the hepatic vein and the portal vein. Liver resection, also known as hepatectomy, is performed to treat malignancies, including hepatocellular carcinoma (HCC) and / or metastasis usually arising from colorectal cancer. Hepatectomy may also be performed to treat intrahepatic bile duct stones or parasitic cysts of the liver. [0005] Traditional liver surgery planning is ...
