Embodiment Construction

[0015] The present invention relates to a method and system for automating an X-ray tube scanner using a 3D camera. Embodiments of the present invention are described herein to give an intuitive understanding of scanner automation methods. Digital images often consist of digital representations of one or more objects (or shapes). Digital representations of objects are often described herein in terms of recognizing and manipulating objects. Such manipulations are virtual manipulations implemented 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.

[0016] Embodiments of the invention generate a personalized 3D mesh model of a person that estimates the person's detailed body pose and shape from RGB-D image data obtained from a depth camera, such as a Microsoft Kinect depth camera. Such a personalized...

Abstract

A method and apparatus for X-ray tube scanner automation using a 3D camera is disclosed. An RGBD image of a patient on a patient table is received from a 3D camera mounted on an X-ray tube. A transformation between a coordinate system of the 3D camera and a coordinate system of the patient table is calculated. A patient model is estimated from the RGBD image of the patient. The X-ray tube is automatically controlled to acquire an X-ray image of a region of interest of the patient based on the patient model.

Description

Background technique [0001] The present invention relates to scanner automation for X-ray image acquisition, and more particularly to X-ray tube scanner automation using 3D cameras. [0002] X-ray scans are typically performed by a technician manually positioning the x-ray tube so that the x-ray scan is focused on an area of ​​interest on the patient. The location and orientation of the x-ray tube relative to the patient relies on the subjective judgment of the technician, which often results in inconsistencies between different x-ray scans. X-ray scanner automation is desirable due to several potential benefits. In addition to improved efficiency of the scanning workflow, x-ray scanner automation may also provide better scan quality than x-ray scans obtained through manual positioning of x-ray tubes by technicians. Contents of the invention [0003] The present invention provides a method and system for automating an X-ray tube scanner using a 3D camera. Embodiments of t...
