Abstract
Disclosed are a non-invasive liver function testing apparatus and method. The non-invasive liver function testing apparatus includes a light source configured to irradiate light onto an object, a light detector configured to detect information about light reflected from the object, a raw data extractor configured to extract raw data, associated with at least one target material constituting the object, from the information detected by the light detector, and a data processor configured to extract liver function-related information, including a correlation with the at least one target material, from the raw data.
Claims20
A non-invasive liver function testing apparatus comprising:
- a data processor configured to store information about a correlation between first raw data, associated with at least one target material of a plurality of first objects and extracted by irradiating light onto the plurality of first objects, and liver function-related information obtained by collecting blood from the plurality of first objects;
- a light source configured to irradiate light onto a second object, the second object comprising the at least one target material;
- a light detector configured to detect information about light reflected from the second object;
- and
- a raw data extractor circuitry configured to extract second raw data, associated with the at least one target material of the second object, from the information detected by the light detector,
- wherein the data processor is further configured to determine liver function-related information corresponding to the second raw data, by using the information about the correlation.

- storing information about a correlation between first raw data, associated with at least one target material of a plurality of first objects and extracted by irradiating light onto the plurality of first objects, and liver function-related information obtained by collecting blood from the plurality of first objects;
- irradiating light onto a second object, the second object comprising the at least one target material;
- detecting, by a light detector, information about light reflected from the second object;
- extracting second raw data, associated with the at least one target material of the second object, from the information detected by the light detector;
- and
- determining liver function-related information corresponding to the second raw data, by using the information about the correlation.
A non-invasive liver function testing apparatus comprising:
- a data processor configured to store information about a correlation between light intensity with respect to a given wavenumber, obtained by irradiating light onto a plurality of first objects and detecting a spectrum acquired by light reflected from the plurality of first objects, and liver function-related information obtained by collecting blood from the plurality of first objects;
- a light source configured to irradiate light onto a second object;
- a light detector configured to detect information about light reflected from the second object;
- and
- a spectrum analyzer configured to extract light intensity with respect to the given wavenumber of the second object, from the information detected by the light detector,
- wherein the data processor is further configured to determine liver function-related information corresponding to the second object, based on the extracted light intensity and the correlation.
