Abstract
A method of designing an x-ray emitter panel 100 including the step of determining a pitch scale, r, to be used in placing x-ray emitter elements 110 on the panel 100, thereby arriving at a specific design of x-ray emitter panel 100 suitable for a specific use.

A method of designing an x-ray emitter panel including an array of x-ray emitters for use as a distributed x-ray source, the x-ray emitter panel for use with an x-ray detector panel, the method comprising the steps of
- choosing a predetermined total number of photons produced by a charge available for a single exposure, Etot;
- and
- choosing a predetermined surface area of the emitter panel, F;
- choosing a predetermined absorption factor due to tissue placed between the emitter panel and the detector panel, ηbre;
- choosing a predetermined maximum emitter-detector panel separation, Dmax;
- choosing a predetermined minimum number of photons that is required to arrive at a detector in the detector panel in order to obtain a viable image, Emin;
- choosing a predetermined density of detectors in the detector panel, ρdet;
- choosing a predetermined dimensionless constant having a value between approximately 10 and 20, A;
- solving an inequality of the form:
- (
