Conteúdo: 	Some measurements, with an inexpensive computed tomography (CT) miniscanner allowing the use of different radiation sources (isotopes or x-ray fluorescence) are presented. The use of differential CT technique as well as the use of tracers like iodine and thulium are introduced to improve the image resolution and contrast. As a preliminary study, a 2-dimensional image of a germinated seed of corn with roots and a 3- dimensional image of water draining in a column of soil, performed with a commercial medical CT, are also presented.
