Tomography is the technology which allows the imaging of a crosssection of an object without cutting the object apart. The most well known application is in medical diagnosis. Crosssections of the human body can be obtained by taking X-rays along a plane perpendicular to the body from various angles. The data from these various X-rays can then be analysed using linear algebra and computer programs to reproduce a picture of the body's crosssection. The result of these assumptions is that each ray will be attenuated by an amount proportional to the number of square regions intersecting the object.
Fractional values arise when the ray passes through only part of a square region.
There may also be some inaccuracy due to the equipment used. The problem of trying to decode an image from such X-ray data is similar to solving the Challenger puzzle, except that in the simplified version of tomography under consideration each cell can only have values either 0 or 1. Using methods developed in the first part, try to determine the image encoded by the data given above. You should keep in mind that your solutions will only be close to 0 and 1 but not exact.
