A reference phantom includes CT-imageable detail together with light-reflective spheres. This item can be placed on a patient table in a known location, following which the diagnostic source can be activated to detect the phantom position relative to the isocentre and camera employed to detect the PSS position. A synthetic image of the phantom can be used for comparison with the CT dataset. This allows improved correlation of the source and the patient support, enable further steps to be taken in enhancing the clinical effectiveness of the apparatus. In-use variations of the isocentre location can be corrected in real time by adjustment of the patient support. Thus, as the isocentre moves, the patient can be moved so as to track the moving isocentre. The linac arm could also be designed differently, as the existing design constraint (that isocentre movement must be limited as far as possible) could potentially be relaxed in order to achieve other aims.

The present invention relates to a method for purifying recombinant HCV single or specific oligomeric envelope proteins selected from the group consisting of E1 and / or E2 and / or E1 / E2, characterized in that upon lysing the transformed host cells to isolate the recombinantly expressed protein a disulphide bond cleavage or reduction step is carried out with a disulphide bond cleavage agent. The present invention also relates to a composition isolated by such a method. The present invention also relates to the diagnostic and therapeutic application of these compositions. Furthermore, the invention relates to the use of HCV E1 protein and peptides for prognosing and monitoring the clinical effectiveness and / or clinical outcome of HCV treatment.

Apparatus and methods for quick acute and chronic pain suppression, particularly useful and effective towards high-grade pains and / or pains resistant to other analgesic drugs such as opiates. One apparatus and method generate synthetic “non-pain” information strings of great clinical effectiveness, allowing high reproducibility of the clinical result. Synthesis of the strings occurs by combining novel geometries of complex waveforms in a sequence, perceived as “self” and “non-pain” by the CNS.

The invention discloses a method and system for clinical effectiveness evaluation of artificial intelligence based medical devices. The clinical effectiveness evaluation system includes a diagnosis result receiving unit receiving diagnosis results for arbitrary clinical data from a plurality of specialists and the artificial intelligence based medical device; a correspondence degree calculation unit calculating a degree of correspondence between the received diagnosis results; a statistical value derivation unit deriving a predetermined statistical value on the basis of the calculated degree of correspondence; and a comparison test unit performing a comparison test on the artificial intelligence based medical device using the derived statistical value.

The invention relates to an environment-friendly production process for high-purity montmorillonite. The production process comprises the following steps: (1) drying, soaking, dispersing and sieving a bentonite raw material to obtain a crude solution of montmorillonite; (2) performing ultrasonic dispersion on the crude solution to obtain suspended emulsion; (3) performing cyclone separation on the suspended emulsion to remove a material with the relative density of more than 2.5g / cm<3>, sieving, standing, and removing water on the upper layer to obtain a material on the lower layer; (4) performing high temperature and high pressure cooperative ultrasonic sterilization on the material on the lower layer to obtain a sterilized material; and (5) performing centrifugal separation on the sterilized material, collecting a material with the relative density of less than or equal to 2.5g / cm<3>, drying, grinding until the average grain diameter of less than or equal to 45mu m, and sieving by using a 325-400-mesh sieve to obtain the montmorillonite. The environment-friendly production process ensures medication safety, clinical effectiveness and controlled quality, the process is simple and environment-friendly, the production efficiency is high, the production cost is low, the product quality is high, and industrial montmorillonite production is easily realized; and high temperature, high pressure and ultrasonic waves are combined for sterilization to ensure safety, reliability and a good sterilization effect.
