Tomography is a method of using different kinds of penetrating radiation to produce a section image of a given 3d body (human or industrial). In medicine, Computed tomography (CT) is a valuable noninvasive diagnostic imaging tool. In a CT procedure, sectional anatomic images of a patient are digitally reconstructed from multiple X-ray projections, therefore exposing the patient to a high dose of radiation. Comparing the radiation dose in a CT procedure to a regular single X-Ray projection, the exposure could be hundreds of time greater in certain organs imaging. The risks associated with high levels of ionizing radiation have led to increasing efforts to develop a CT scanner based on Ultrasound radiation. Ultrasound technology has been used in medical application for decades serving as a reliable, easy to use, cheap and safe imaging tool. The US based CT technique is not fully developed yet. A part of the world going effort to establish a non-ionizing, safe imaging method, in this work we present the development of a simulative, finite elements based, Ultrasonic CT machine. We then utilized the finite element method to build a ring array of 300 point ultrasonic transducers. These surround the object under test, producing and receiving the ultrasonic radiation from all possible directions. This method is used to numerically solve Partial Differential Equations and simulate the response of solid materials under different loads. We model slices representing both human anatomy and metals under loads to obtain reconstruction of the models.
