Implement a tomographic backprojection module

[fredericpoitevin]

What?

Forward model:
Given a volume V and N simulation_parameters, use the linear simulator to simulate images:
X = simulate(V, simulation_parameters)

Backprojection:
Given images {X} and simulation_parameters, reconstruct the starting volume:
V = \sum_i back_project(X[i], simulation_parameters[i]).

Why?

• Useful to "close the simulation loop", for testing.
• Could be used as a diagnostic for validation, benchmark.

Where?

• Write backproject.py in the simSPI/simSPI/linear_simulator folder
• (optional) Demonstrate on an example by placing a notebook in the notebooks folder.

How?

TBD
