Personalised 3D vascular models are valuable for diagnosis, prognosis and
treatment planning in patients with cardiovascular disease. Traditionally, such
models have been constructed with explicit representations such as meshes and
voxel masks, or implicit representations such as radial basis functions or
atomic (tubular) shapes. Here, we propose to represent surfaces by the zero
level set of their signed distance function (SDF) in a differentiable implicit
neural representation (INR). This allows us to model complex vascular
structures with a representation that …
