- Artificial Intelligence Machine Learning based
System for accurate, rapid and reproducible
analysis of Prostate Cancer - Examination of histological specimens under the
microscope by a pathologist is one of the most
reliable methods used in detection of prostate
cancer. This is carried out by examining the
glandular architecture of the specimen by the
most common method for histological grading of
prostate tissue - the Gleason Grading System. - The cancer tissue is classified from 1 to 5
grades however, in the recent times, this
common method is found to be ineffective, reason
being - Analysis on visual interpretation lacks
reproducibility - It is limited by intra- and inter-pathologist
variability

Our Machine-based scoring algorithms
- Our solutions to resolve the challenges appearing
from Gleason Grading - Fully automated solution End to end solution
with robust and efficient algorithm modules. - Intelligent Segmentation module that works on
human perceptible color spaces to detect cell
nuclei based on recognizable patterns like area,
shape, intensity etc. - Automatic detection of glandular lumens based on
the clustering of identified cell nuclei and
other features. - Robust feature extraction module to extract
structural, morphometric, texture, nucleo-
cytoplasmic ratio and color features for
detected cell nuclei and identified glandular
regions. - ANN (artificial neural network) based classifier
- Feature fusion and feature ranking techniques
for representation to the Neural network based
classifier. - The classifier is trained to distinguish between
moderately and poorly differentiated glands. - Object level tumor grading is done using feature
characteristics for malignant and benign cell
nuclei like mean intensity, area, standard
deviation of intensity etc. - Key Differentiator
- Easily retrainable machine learning system.
- High classification accuracy.
