US 10,379,067 B2 · Method and system for liquid detection

Abstract

Systems and methods for liquid detection are disclosed. An illustrative method for liquid detection herein may include implementing CT imaging and XRD imaging on one or more liquid planes of liquid contained in a container at once by rotating the container so that X-rays from a same radiation source scan a whole area of each of the one or more liquid planes, and generating a substance identification result for the liquid contained in the container based on a CT image and a XRD image, wherein the CT imaging and the XRD imaging are implemented on a same liquid plane or different liquid planes. Consistent with various aspects and features, implementations may identify substances contained in the liquid more quickly and accurately.

Dependent claims

A method for liquid detection, comprising:

implementing CT imaging and XRD imaging on one or more liquid planes of liquid contained in a container at the same time by rotating the container so that X-rays from a same radiation source scan a whole area of each of the one or more liquid planes, wherein the X-rays from the radiation source are separated into X-rays for the CT imaging and X-rays for the XRD imaging;
and
generating a substance identification result for the liquid contained in the container based on a CT image and a XRD image, wherein the CT imaging and the XRD imaging are implemented on a same liquid plane or different liquid planes.

A system for liquid detection, comprising:

a radiation source configured to emit X-rays;
a primary collimator provided at the downstream of the radiation source and configured to separate the X-rays from the radiation source into X-rays for CT imaging and X-rays for XRD imaging;
a CT imaging apparatus configured to implement CT imaging by utilizing the X-rays for CT imaging;
a XRD imaging apparatus configured to implement XRD imaging by utilizing the X-rays for XRD imaging;
a carrying apparatus configured to rotate a container containing liquid, so that the X-rays from the radiation source scan a whole area of each of one or more liquid planes of the liquid contained in the container, wherein
the CT imaging apparatus and the XRD imaging apparatus implement the CT imaging and the XRD imaging on the one or more liquid planes at the same time, and a CT image and an a XRD image are utilized to generate a substance identification result for the liquid contained in the container.
