Cone beam X-ray scatter removal via image frequency modulation and filtering Abstract: We present a novel method for rapid removal of patient scatter from cone beam (CB) projection images that requires no scatter measurement, physical modeling or strong assumptions regarding the spatial smoothness of the scatter distribution.

· From there, you know the drill: calculate the determinant Δ = b 2 – 4 a c then depending on its value: If Δ < 0, the ray is not intersecting the cone. If Δ = 0, the ray is intersecting the cone once at t = − b 2 a. If Δ > 0, the ray is intersecting the cone twice, at t 1 = − b – Δ 2 a and t 2 = − b + Δ 2 a. But wait!

In a traditional cone-beam CT system, the cost of product and computation is very high. In this paper, we propose a transversely truncated cone-beam X-ray CT system with a reduced size detector positioned off-center, in which X-ray beams only cover half of the object. The reduced detector size cuts the cost and the X-ray dose of the CT system.

· So a 3d cone. One solution would be to import a model of a 3D cone and use the OnCollision methods. You could use a method like the one explained in this blog post. But instead of casting in all directions, you would cast in the direction the player/entity is facing. And you would need to do a 3D grid of rays in the shape of a circle/cone.

It’s called a cone-beam because the x-ray beam is literally in the shape of a cone, where traditional CT scans use fan shaped x-ray beams. The machine takes nearly 600 “slices” of information

Cone tracing solves certain problems related to sampling and aliasing, which can plague conventional ray tracing. However, cone tracing creates a host of problems of its own. For example, just intersecting a cone with scene geometry leads to an enormous variety of possible results. For this reason, cone tracing has remained mostly unpopular.
