Solution for the presentation of spectroscopic analysis of kidney stone data
Vilnius University Hospital Santaros is looking for a digital solution that uses artificial intelligence algorithms to compare the composition of kidney stones with baseline spectra and to select possible spectra and stone compositions.
Contex
- Currently, the analysis of the composition of kidney stones is based on “wet” qualitative chemistry reactions, which identify different anions and cations in the composition of stones. The wet chemistry method has the disadvantage that it does not allow the identification of the exact compound, and in mixed composition stones the percentage results are only given in terms of ions and radicals.
- Recently, an extremely accurate and simple test, Fourier transform infrared spectroscopy (FTIR), has become particularly widely used worldwide. The Centre for Urology at VUL SK, in collaboration with scientists from the Faculty of Physics at VU, has started testing this method.
- The different positions of the oscillating bands in the spectrum can be used to determine what constitutes the material under study. It is the most accurate and advanced method for both qualitative and quantitative analysis of the chemical composition of the kidney stone, by determining the chemical composition, structure and concentration of the constituent material. However, FTIR output requires special attention by the researcher in comparing spectra, experience and is time consuming in determining the composition of the stone.
Solution
- The solution, using artificial intelligence algorithms, should allow for a very fast recognition of the composition of the kidney stone, which would allow for the optimal choice of stone fragmentation.
- The solution should be able to retrieve the spectrogram from the spectrograph or from the computer controlling the spectrograph (be able to recognise the outputs (graphs) of the vibrational spectroscopy software OPUS).
- The solution should compare the spectrogram with the baseline spectra, choosing from 500 (five hundred) possible spectra of the stones.
A detailed description of the functional and non-functional requirements of the solution is given in Annex 3 ‘Technical Specification’ to the contract.
