The invention relates to a method for producing a lens for an ultrasound apparatus, as well as to an apparatus comprising the lens. The method comprises choosing a source point, providing a treatment volume situated inside a bone tissue model, providing a plurality of nodes distributed inside the treatment volume, and simulating the emission of a spherical wave from each of the nodes. Thus, a simulated wave front is created, in which each spherical wave has an amplitude and a phase, there being at least two nodes with different amplitudes and/or phases. The simulated wave front is received on a receiving surface. On the basis of the processed results, a holographic lens surface is designed, which can generate a wave pattern equivalent to the simulated wave.

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.
