IIT Kharagpur and Tata Medical Centre have set up an open architecture image biobank to help cancer research in the country. Titled as CompreHensive Digital ArchiVe of Cancer Imaging (CHAVI) it will address the emerging field of imaging-related research and will be India’s first step towards harnessing artificial intelligence and deep learning methods to find solutions of medical complexities in the field of image banking.
IIT Kharagpur and Tata Medical Center have been jointly working on several novel educational and research programmes including Masters and Fellowship courses to enable this trans-disciplinary research that amalgamated technology and medicine. The two institutions have joined hands in initiating a pilot project on developing an image data bank for cancer patients, in particular, the present focus is radio oncology. The project has been undertaken by IIT Kharagpur through the National Digital Library Initiative (NDLI) of MHRD. The overarching aim here is to build up a national bank of annotated images with a flexible query interface and link it with a pipeline of radiomic services for advance radiological research in large image datasets.
The CHAVI project is the first of its kind. With the CHAVI project, as a beginning, we have chosen cancer imaging database along with Tata Medical Center because of their tremendous expertise. Cancer is one of the most dreaded diseases in our country. If we are able to create a very well defined, annotated database, it will help researchers as well as doctors to be able to do early, more accurate diagnosis and provide better treatment for our people which is a lot more cost effective – Prof. Partha Pratim Chakrabarti, Principal Investigator of NDLI.
As a pilot, radiation oncology related images are being banked within the NDLI CHAVI RO project. It is a prototype system which is under development addressing various such issues. It is also being developed considering multi-institutional participation in building a national image data bank.
Once the pilot project is successful, it can be scaled up to a larger set of medical images. Imaging methodology can then be combined with AI to enable reach of treatment to more people as well as provide targeted therapy based on individual symptoms. This should enable doctors like never before, and revolutionize the way doctors interact with patients and systems.
AI for the medical vertical has three pillars. Descriptive analysis that will help education – students anywhere in the country can access the bank to look at the images and learn from there. Predictive Analysis will help doctors diagnose better. And then Prescriptive analysis that will help doctors reduce the scope of treatment based on past use cases.
We need more affordable solutions in India for cancer treatment, majority of our patients are middle class and lower middle class and cannot afford genomic analysis. Image banking combined with predictive/prescriptive AI can enable us to identify signatures as a much more cost effective alternative – Dr Sanjoy Chatterjee, Tata Medical Center.
While Tata Medical Center has created a large repository of medical data and images of cancer patients including outcomes of treatment in many cases, there are various challenges while building this system. The first and foremost is in preserving anonymity of patients as well as maintaining adequate referential integrity, a necessity for carrying out useful research.
To enhance the CHAVI project, the two institutions organized a workshop titled – “Structuring a Collaborative National Image Banking Program” on 26th July 2019 at Tata Medical Center, Kolkata, supported by MHRD through the NDLI project. The workshop which was coordinated by Dr. Sanjoy Chatterjee and Prof. Jayanta Mukhopadhyay from IIT Kharagpur involved presentations and panel discussions with experts in medical and Computer Science / AI domains. Several expert doctors from India, USA and UK and specialists in the area of Computer Science from India also took part in the daylong proceedings.
What the experts said !!
The scope of image banking is to enable cancer research and move it forward, to access data that is more diverse and come from different centres, different patients and different ethnic groups to help doctors make more informed decisions and deliver personalized treatments – Dr. Emiliano Spezi, Cardiff University, USA
If you have an image bank where you can collaborate all your images, and then you look at certain features, you can probably come up with information which goes beyond the human eye. Imaging when combined with pathological information can then improve outcomes for our patients – Dr. Simon Pavamani, CMC Vellore
It is a kind of personalized medicine. Where a set of images of a particular kind is treated in a particular way which helps predict a specific treatment for each individual patients – Dr. Subhas Gupta, AIIMS, New Delhi.
