Abstract:
A method of constructing a three dimensional image from a two-dimensional X-ray projection of an object, the method comprising steps of:a) filling the object to be imaged with an X-ray agent, said X-ray agent attenuating X-rays; b) generating an X-ray absorbance profile by irradiating said agent-filled object with X-rays substantially perpendicularly to a selected plane of said object, said object is substantially symmetrical about said selected plane thereof, wherein said X-ray absorbance profile has an x, y coordinates on said selected plane and has an absorbance parameter (P) related to a distance (D) travelled by the X-ray; and c) producing a three-dimensional image of said object using said X-ray absorbance profile, by dividing the X-ray absorbance parameter by two and processing said divided absorbance parameter into a z-coordinate with respect to the x, y coordinate of the corresponding absorbance profile.
