Abstract: A device and a method for obtaining densitometric images which comprise at least one radiological device, at least one depth sensor, and image processing means, which combine the radiological absorption information from the set of recorded radiological images obtained with the radiological systems with the distances of the traversed material, provided by the three-dimensional reconstruction of the objects obtained by means of the depth sensors.

Abstract: The GAMMA/RF compact, hybrid and integrated system for PET-SPECT/MR simultaneous imaging of the invention comprises a GAMMA/RF device that integrates an RF coil, of the type used in conventional MR systems, with GAMMA radiation detector modules of the type used in PET or SPECT systems, so that combined PET or SPECT and MR images are obtained.

Abstract: The invention relates to a portable mini gamma camera for intrasurgical use. The inventive camera is based on scintillation crystals and comprises a stand-alone device, i.e. all of the necessary systems have been integrated next to the sensor head and no other system is required. The camera can be hot-swapped to any computer using different types of interface, such as to meet medical grade specifications. The camera can be self-powered, can save energy and enables software and firmware to be updated from the Internet and images to be formed in real time. Any gamma ray detector based on continuous scintillation crystals can be provided with a system for focusing the scintillation light emitted by the gamma ray in order to improve spatial resolution. The invention also relates to novel methods for locating radiation-emitting objects and for measuring physical variables, based on radioactive and laser emission pointers.

Abstract: The invention relates to non-proteolysable oligopeptides that inhibit glycoprotein 41 of the AIDS virus. More specifically, the invention relates to the identification of oligopeptides, particularly hexapeptides, (D), (L) or mixed, preferably D-hexapeptides, which inhibit the binding of a retrovirus to a target cell, thereby providing novel therapies against infection from the human immunodeficiency virus (HIV). The invention also relates to the use of said D-hexapeptides in the form of single components or complex mixtures as prophylactic or therapeutic agents for retroviral infections, especially human immunodeficiency virus type 1 (HIV-1).
