Tangent Tuesday: talk by Nabanshu Gogoi, IISERTVM on 10 Nov 2026

We are back with another episode of Tangent Tuesday! Join us for an interesting exploration of inverse problems and the mathematics behind medical imaging.

Abstract

Some of us have had the misfortune of lying down in a Saddam Hussein hiding-spot-esque position on a CT scanner, and while the machine whizzes and readies you to teleport to another dimension (not), I am sure many of us have wondered whether there is mathematics behind this contraption. I shall answer this to those who are still wondering: there is, and it is simple!

This talk aims at introducing the wonderful world of (applicable) mathematics of medical imaging using the colourful language of analysis and later, partial differential equations, all motivated and proved (maybe).

I will set up the Radon transform, talk about the Fourier Slice Theorem, and make my way into the broad field of inverse problems, particularly the Calderón problem, having worked on it over the summer and for my thesis.

All are warmly welcome to attend!
