Siddon's ray-voxel intersection
WebA ray ~r originating from a source position ~s traverses a voxel volume and hits a detector pixel at location d~. Along its intersection with the volume, the latter will be sampled in steps of ~r(cf. Fig. 2). For convenience, the coordinate system is aligned with the voxel grid, i.e. the origin is at the corner of the voxel volume and http://static.tongtianta.site/paper_pdf/2863985e-c0c2-11e9-983d-00163e08bb86.pdf
