X-ray determination of an object’s location within a body

A method of determining a location of an object within a body, the method comprising the steps of:

• providing an x-ray detector panel;
• providing a first x-ray emitter at a first location relative to the x-ray detector panel, the first x-ray emitter configured to emit a first cone of x-rays therefrom such that the first cone of x-rays impinges the x-ray detector panel;
• providing a second x-ray emitter at a second location relative to the x-ray detector panel, the second location spaced from the first location, the second x-ray emitter configured to emit a second cone of x-rays therefrom such that the second cone of x-rays impinges the x-ray detector panel;
• activating the first x-ray emitter and the second x-ray emitter concurrently to produce a single two-dimensional image at the detector panel indicative of absorption of the first and second cones of x-rays by a body placed therebetween;
• determining in the single two-dimensional image respective first and second positions of an object projected by the first and second cones of x-rays respectively;
• and
• establishing a site of the object relative to the x-ray detector panel from the first location, second location, first position and second position, wherein the site of the object is determined in three spatial dimensions from the single two-dimensional image.
