Computerized tomography or diagnostic TC Tecnica radiologica, through which it is possible to visualize sections of parts of the organism. Such technique allows to get images of organs that cannot be radiografate since don't possess a contrast, as for instance those formed by soft fabrics as the brain. The term computerized tomography currently replaces the old denomination computerized axial tomography or TAC.

TECHNIQUE OF THE TC

The investigation tomografica is effected through the use of a said device body scanner or analyser of images for the computerized tomography. Such tool wheel of 180° around the body of the patient, opportunely sending a thin bundle of X rays in over one hundred select different points. A determined number of crystals of ioduro of caesium, prepared in particular positions, it serves for gaining the brushes of radiation in exit quantifying the degree of absorption of the same radiation and, therefore, the thickness of the fabrics and the bones. The picked data come then envoys to an electronic computer that converts them in an image on a screen.

APPLICATION OF THE TC

The great advantage of the technique of the computerized tomography is represented by the possibility to get images of sequential plans of the organ, while the traditional radiography “it flattens” the three-dimensional structures overlapping the details, making of it therefore less clear the interpretation. The TC has entered the clinical practice in the seventies, and you/he/she was welcomed ahead by the radiologists as a gigantic footstep in the diagnostic one not invasiva for images, kind as it regards the precocious diagnosis of tumors in organs what the brain and the bellows.
