Abstract: A biomedical device (1) for robotized rehabilitation of a human upper limb, particularly for neuromotor rehabilitation of the shoulder and elbow joint, includes a first rigid rod (2) and a second rigid rod (3), both of which can be associated with the upper limb (4) of a patient (5) and are articulated to each other at two adjacent ends (2a, 3a) thereof by way of a first universal joint (6) which can be arranged proximate to the elbow joint (7) of the upper limb (4).

Abstract: A scintillation device with high resolution includes a detection unit (3) to convert into light radiation an ionising radiation originating from a source under examination and a collimator (2) made of a material with high atomic number 3nd including a plurality of grids (4), the grids (4) co-operating with each other in mutually sliding fashion in a transverse direction to the direction of detection (R) to provide a partial coverage of the detection unit (3) in such a way as to expand and reduce in an adjustable manner a surface area of the detection unit (3) offered to the radiation.

Abstract: An apparatus for culturing eucaryotic and/or procaryotic cells comprising an incubator (10), operating means (20) to generate predetermined environmental conditions within the incubator (10), and one or more control devices (30) to control the operating means (20) depending on the desired environmental conditions; apparatus (1) further comprises an electromagnetic-insulation chamber (40) housing the incubator (10) and the operating means (20), the control devices (30) being on the contrary located externally of said insulation chamber (40).

Abstract: A miniaturized scintigraphic device comprising a collimator (1), internally having a multiplicity of equal conduits (10) of determined length, identified and separated by septa (11) of minimum thickness in relation to the energy of the radiation, terminating in a common end plane (12) on the side opposite to the source of the event to be measured, comprising a scintillation crystal structure (2) and at least a photomultiplier (3), in which the scintillation crystal structure is constituted by a multiplicity of individual crystals (20) with polygonal section, each integrally integrated in proximity to the end, oriented towards the photomultiplier (3), of each conduit (10) of the collimator (1), having conforming polygonal section, and arranged in such a way that all the base faces (21) of the crystals (20) oriented towards the photomultiplier (3) are mutually coplanar and lying on a plane parallel to said common end plane (12) of the collimator (1).

Abstract: A scintigraphic device, comprising a collimator, a scintillation crystal structure, a plurality of photomultipliers, electronic circuits for the determination of the position co-ordinates (XY) and energy of the event and their amplification for their subsequent transfer to an electronic processor, wherein photomultipliers (31, 32, 33, 3n) are positioned mutually adjacent, each provided with its own independent electronic circuits (121, 122, 123, 12n), and a circuit (13) for interrogating the respective synchronism signals drawn from the respective electronic circuits (12) determines the signal indicating the photomultiplier (13) that detected the event and enables only a corresponding analogue switch (14) to transfer the signals carrying the position co-ordinates of the event from the enabled electronic components (12) to an analog to digital converter (A/D).

Abstract: The miniaturized gamma camera has all specific functionalities of gamma cameras, with extremely high spatial resolution (about 1-2 mm) and dimensions of about 22 mm×22 mm of active area and total size of about 35 mm×35 mm, such as to fit in one of the surgeon's hands and to be handled with absolute ease.

Abstract: The gamma camera, able to be developed in areas of any size and unlimited, presents such a thickness as to be considered flat and of minimal bulk and it can be assembled in individual modules to be attached one to the other solving the problem of dead zones between individual PSPMTS, with values of intrinsic spatial resolution in the order of 1 mm. The application of the present invention may range from the medical field (PET, SPECT, SPEM, PEM, etc.) to employment in astrophysics.
