Algorithm I. Implementation of the FBP algorithm (on host).

Input:p

Output:${\widehat{\mathit{\alpha }}}_{\mathrm{fbp}}$

1: $w=-C_p{R}^s{\Delta }_{{\theta }^s}{\Delta }_{{\varphi }^s}/\left(\pi \beta c_0^3{\Delta }_t\right)$ {Precalculate the common coefficient}

2: $\mathrm{T}\_\mathbf{p}\leftarrow \mathbf{p}$ {Bound data to texture memory}

3: K_fbp  ⟨⟨⟨ (Ny, Nx), (Nz, 1, 1) ⟩⟩⟩ (ω, $\mathrm{D}\_{\widehat{\mathit{\alpha }}}_{\mathrm{fbp}}$)

4: ${\widehat{\mathit{\alpha }}}_{\mathrm{fbp}}\leftarrow \mathrm{D}\_{\widehat{\mathit{\alpha }}}_{\mathrm{fbp}}$ {Copy data from global memory to host}
