Tomographic imaging with a stripe-like shaped sensor

Abstract

Tomographic imaging using an imaging sensor that has a stripe-like shape is disclosed where a stripe sensor is mechanically scanned over a sample at different angles. For a single stripe detector imaging, linear motion and angular rotation are required. Single stripe sensor imaging may be performed using an elongated inductive coil detector. By utilizing an array of parallel stripe sensors that can be individually addressed, two-dimensional imaging can be performed with rotation only, eliminating the requirement for linear motion, e.g. with parallel coils array. Imaging with a stripe-type sensor of particular width and thickness (where width is much larger than thickness) is resolution limited only by the thickness (smaller parameter) of the sensor. Multiple sensor families can be produced where this imaging technique may be beneficial such as magneto-resistive, inductive, SQUID, and Hall effect sensors, and particularly in the field of magnetic resonance imaging (MRI).
