Problems solved by technology

For most surgeries, the corresponding volume measurements are usually not performed intraoperatively, possibly because performing such volume measurements would interfere too much with the surgical workflow

Embodiment Construction

[0009] The present invention relates to a method and system for calculating the volume of resected tissue in a surgical treatment from intraoperative image data, such as laparoscopic or endoscopic image data. Embodiments of the invention are described herein to give an intuitive understanding of the method for calculating the volume of resected tissue from intraoperative image data. Digital images usually consist of digital representations of one or more objects (or shapes). This paper generally describes digital representations of objects in terms of recognizing and manipulating objects. Such manipulations are virtual manipulations done in the computer system's memory or other circuitry / hardware. Accordingly, it should be understood that embodiments of the present invention may be implemented within a computer system using data stored within the computer system.

[0010] An increasing number of minimally invasive surgical procedures are being performed using cameras, such a...

Abstract

A method and system for calculating a volume of resected tissue from a stream of intraoperative images are disclosed. A stream of 2D / 2.5D intraoperative images of resected tissue of a patient is received. The 2D / 2.5D intraoperative images in the stream are acquired at different angles with respect to the resected tissue. A resected tissue surface is segmented in each of the 2D / 2.5D intraoperativeimages. The segmented resected tissue surfaces are stitched to generate a 3D point cloud representation of the resected tissue surface. A 3D mesh representation of the resected tissue surface is generated from the 3D point cloud representation of the resected tissue surface. The volume of the resected tissue is calculated from the 3D mesh representation of the resected tissue surface.

Description

Background technique [0001] The present invention relates to estimating the volume of resected tissue in surgical treatments, and more particularly to estimating the volume of resected tissue from 2D / 2.5D intraoperative image data. [0002] Surgical treatment often involves resection and removal of tissue from a patient, especially tumors in cancer patients. In such cases, it is crucial to know exactly the extent of tissue to be removed. For example, patient survival outcomes in neurosurgery correlate with residual tumor volume after resection, liver function correlates with viable liver tissue remaining after tumor resection in liver surgery, and renal function after partial nephrectomy correlates with preserved kidney related to volume. Volumetric measurements of surgical targets are often made on preoperative images such as computed tomography (CT) images or magnetic resonance (MR) images, which help guide clinical decision making. For most surgeries, the corresponding v...
