We find that the use of organically inspired 3D envelopes struggles to capture the different states of matter that surgeons encounter during operations. The tumour is not a clearly delimited foreign body; it is an alteration of the brain matter itself. This alteration is not uniform but progressive, making the tumour a diffuse entity that is difficult to circumscribe. Current images therefore pose a problem of accuracy of representation and can lead to misinterpretation. How then can we represent the uncertainty, the information actually available, without extrapolating our knowledge by using inadequate forms?

Hypothesis

Our experimental attempt is to remove the organically inspired 3D shapes and return to a representation system based on the matrix of voxels - the volumetric pixels of the MRI scan - which constitute the real information available, and then to develop a meta-commentary capability on each voxel position. We hypothesise that this shift in the mode of representation allows us to move from realistic to real. By leaving the realism of 3D forms, we enter an aesthetically abstract model, a kind of mental space that expresses with the same intensity the recorded information and the unknown that surrounds it, thus offering a representation that is closer to the real level of information available on the observed brain.

Seeing Through Digitised Matter

MRI scanned material produces a dataset of voxels: volumetric pixels, arranged in a matrix, which record a state of the material with coordinates. The voxel is therefore the smallest grain of information recorded. It is nevertheless relatively coarse (1mm on a side), in relation to the matter analysed (the brain). The voxel is usually represented as an opaque cube, which varies in colour. This is why MRIs are generally observed on screen in the form of successive slices to allow the complete information of the recording to be taken into account. The challenge for us is to analyse and work on the shape of the voxel to enable the volumetric aspect of the information to be perceived without necessarily using slices that would act as filters for the information.
