Medical Text and Image Analytics - overview
Medical Text Analytics
The Medical Text Analysis System (MedTAS
) is a UIMA
-based, modular and flexible system that uses advanced Natural Language Processing (NLP) techniques to extract structured information from unstructured data sources, such as pathology reports, clinical notes, discharge summaries, and medical literature. MedTAS is also a development platform that is adaptable to customer and domain requirements. It has been designed to operate within institutional systems, and seamlessly integrates with IBM products, such as the DB2 Data warehouse.
Implementations of MedTAS have been developed for major medical institutions. MedTAS/P is a version customized for the pathology domain. It is based on a novel representation of cancer, its characteristics and disease progression.
High Performance Medical Imaging
Our group has a focus on high-performance medical image analytics. We have successfully demonstrated the power of the IBM Cell broadband engine
in this space, gaining up to 60x speed-up on a linear registration task using cell over an x86 implementation. We are extending the registration algorithm for soft tissues using a non-linear transformation.
Another effort is in the area of benchmarking – comparing the performance of key image analytics algorithms and their sub components between implementations on the IBM Cell Broadband Engine and those on GPU implementations. Of particular interest are CT Reconstruction algorithms.
Multimodal Medical Informatics
The Multimodal Medical Informatics project aims at providing systems and tools to support clinicians' decisions and reduce uncertainties at different stages of the clinical care by: analyzing, organizing, fusing and summarizing information embedded in patients' multimodal medical records for enhanced access to data. We built a prototype – the Medical Analytics Platform geared towards helping Radiologists access and process images taking advantage of the IBM Cell Broadband Engine and correlating them with analyzed and relevant textual sources such as pathology and radiology reports.
