Abstract: The methods comprise: a) obtaining a 3D volume of the object containing two different sub-volumes identified as: well-defined zone (S) and not-well-defined zone (BZ) sub-volumes; b) generating well-defined zone (S) and not-well-defined zone (BZ) patches from the two sub-volumes; c) automatically identifying the possible channels by means of automatically obtaining candidate channels regions (CCR), dilating the perimeters of the well-defined zone (S) patches. The method includes embodiments for a layered approach, an EAM polygonal mesh approach and a volume approach. The computer program product is adapted to implement part or all of the steps of the method of the invention. The EAM system comprises computing navigation means implementing the method of the invention.

Abstract: Described herein is a pulsator device that can be used for generating a pulsed flow starting from a substantially constant flow, for example in reactors for cell growth and other applications in which it is desired to have available pulsed irroration flows. The device comprises a deformable body that is able to define a duct for passage of a substantially constant flow of a fluid subjected to pumping. Associated to the deformable body is at least one actuation chamber that is selectively expandable between at least one contracted condition and at least one extended condition of pumping so as to produce a variation of the section for passage of said fluid through the duct. The variation of the section of passage through the duct is able to cause the generation of a pulsed flow of the fluid subjected to pumping.
