A Predictive Analytics Workflow on DICOM Images using Apache SparkSummit 2017

In healthcare, DICOM is an international standard format for storing medical images (MRI/CT representations). Each image has associated with it embedded metadata and pixel data. There is currently a tremendous amount of effort in healthcare to incorporate image analytics within clinical data analysis. Apache Spark is a natural framework to integrate these efforts. This session presents an analytics workflow using Apache Spark to perform ETL on DICOM images, and then to perform Eigen decomposition to derive meaningful insights on the pixel data. The workflow integrates a Java based framework DCM4CHE with Apache Spark to parallelize the big data workload for fast processing. Users can extract features based on the metadata and run efficient clean/filter/drill-down for preprocessing. See a demonstration of predictive analytics with visualization using the metadata to derive insights, such as likelihood of a condition or efficacy of medication administered. The speakers will also present performance benchmarks of this workflow on various datasets and cluster configurations to demonstrate the benefits of running this kind of analysis workflow on Apache Spark.
