Uterine cervical cancer computer-aided-diagnosis (CAD)
First Claim
1. A process for diagnosing cancer in a cervix, comprising:
- spacially registering onto a single image of said cervix multiple calibrated data sets, each of said data sets being a different type of calibrated data which can be utilized for the detection of cervical cancer;
applying at least two selected diagnostic algorithms to at least one of said multiple data sets to extract colposcopic features from said data sets to obtain classifications of said extracted features;
combining classifications of said extracted features;
assessing examination adequacy of said combined classifications; and
if said examination adequacy is sufficient, determining tissue diagnosis;
whereby reliability of said tissue diagnosis is increased.

Abstract
Uterine cervical cancer Computer-Aided-Diagnosis (CAD) according to this invention consists of a core processing system that automatically analyses data acquired from the uterine cervix and provides tissue and patient diagnosis, as well as adequacy of the examination. The data can include, but is not limited to, color still images or video, reflectance and fluorescence multi-spectral or hyper-spectral imagery, coherent optical tomography imagery, and impedance measurements, taken with and without the use of contrast agents like 3-5% acetic acid, Lugol'"'"'s iodine, or 5-aminolevulinic acid. The core processing system is based on an open, modular, and feature-based architecture, designed for multi-data, multi-sensor, and multi-feature fusion. The core processing system can be embedded in different CAD system realizations. For example: A CAD system for cervical cancer screening could in a very simple version consist of a hand-held device that only acquires one digital RGB image of the uterine cervix after application of 3-5% acetic acid and provides automatically a patient diagnosis. A CAD system used as a colposcopy adjunct could provide all functions that are related to colposcopy and that can be provided by a computer, from automation of the clinical workflow to automated patient diagnosis and treatment recommendation.
