Abstract: A system for obtaining a tomographic image of an object having a plurality of candidate object image locations is provided. The system includes a processor containing object density information as well as a source of radiation energy for irradiating the object wherein the source of radiation is under the control of the processor. A radiograph of the object is provided and applied to a digitizer for indicating a selected object image location on the radiograph and transmitting the selected location to the processor. The processor then controls the source of radiation to adjust the level of radiation in accordance with the transmitted location and the stored object density information. The processor also controls a translator to adjust the relative object to equipment position in accordance with the transmitted location signal. The source of radiation energy can be moved through pluridimensional patterns.
