An exemplary embodiment of the present invention provides a three-dimensional virtual liver surgery planning system including: a digital imaging and communications in medicine (DICOM) receiving module which receives an abdomen computer tomography (CT) volume data set from a picture archiving and communication system (PACS) server; a DICOM loading and noise removing module which loads the received abdomen CT volume data set and remove noises; a standard liver volume estimation module which estimates a standard liver volume (SLV) from the denoised abdomen CT volume data set; a liver extraction module which extracts a three-dimensional liver region; a vessel extraction module which extracts a three-dimensional vessel region including a portal vein, a hepatic artery, a hepatic vein, and an inferior vena cava (IVC); a tumor extraction module which extracts a three-dimensional tumor region; a liver segmentation module which divides the extracted three-dimensional liver region into several segments using landmarks which are selected by a user or a segmentation sphere; and a liver surgery planning module which makes a three-dimensional liver surgery plan using a resection surface, a liver segments, or the segmentation sphere. |
