Résumé

Disc degeneration diseases appear due to the natural process of dehydration of the intervertebral disc (IVD). Treatment options help to relieve pain but still impact the spine integrity in the form of a decrease in mobility and acceleration of the degenerative process of the neighbouring discs. Early diagnosis of degeneration is therefore interesting to limit the progression of the diseases and avoid pain. Effective diagnosis methods exist such as magnetic resonance imaging or computerized tomography but they lack flexibility and time effectiveness. We propose the use of photoacoustic imaging as an alternative quantitative method to assess the state of the IVD. We present the results of a preliminary study where numerical reconstructions of the principal chromophores composition (water/collagen) of the IVD were obtained using a gradient descent scheme.
