Abstract: Disclosed are an imaging method and an arrangement for the computer-assisted evaluation of projected object trajectories obtained from a computer-tomographic measurement. According to the inventive method, the trajectories are arranged in a previously known sequence into a projection matrix as traces of the respective voluminous elements, and the following steps are iterated until a sufficient reconstruction quality has been attained; (a) at least one of the traces is selected; (b) a reconstructed element that is true to the original position is formed from each of the selected traces so as to be added to a reconstructed image; (c) the selected traces are removed from the projection matrix.

Abstract: The invention is directed to a method and a kit for calibrating a photoluminescence measurement system, in particular a fluorescence measurement system. The kit includes a number of fluorescence standards i and their corrected and certified fluorescence spectra Ii(?), whereby the fluorescence standards i are selected, so that their spectrally corrected fluorescence spectra Ii(?) cover a broad spectral range with high intensity. The standards are characterized by large half-widths FWHMi of their bands of at least 1400 cm?1. According to the method of the invention, partial correction functions Fi(?) are generated by forming the quotient of the measured fluorescence spectra Ji(?) and the corresponding corrected fluorescence spectra Ii(?), which are then combined to form a total correction function F(?) for a broad spectral range.

Abstract: A method for producing a bioactive bone cement and a bone cement kit for anchoring artificial joints and for filling out bone defects. The method avoids polymerization-linked by-products and disadvantageous effects, while at the same time providing the bone cement with long-term stability. The inventive method uses a monomer-free polymethylmethacrylate, which is mixed with a suitable non-toxic solvent, and a bioactive, vitreous-crystalline material with a particle size ranging from >20 to 200 ?m, having 15–45 wt. % CaO, 40–45 wt. % P2O5, 10–40 wt. % ZrO2 and 0.7–3.5 wt. % fluoride, having apatite and calcium zircon phosphate as main crystal phases and a glass phase as an auxiliary component until a flowable mixture is obtained. The invention also relates to a bone cement kit having said components.

Abstract: The invention concerns an apparatus for generating and/or detecting radio frequency (RF)-B1 fields in an investigational volume (10) of a magnetic resonance (MR) device, wherein the apparatus comprises a tubular surface coil (1; 20; 30; 41–44; 51–54; 61) which is formed from a conducting strip and is capacitively closed at least two neighboring ends, wherein the ratio between length L and width W of the strip is ?30, and wherein the volume under investigation (10) is disposed outside of the space surrounded by the strip, bordering an outer surface (9) of the surface coil (1; 20; 30; 41–44; 51–54; 61) such that the B1 field lines, generated by the surface coil (1; 20; 30; 41–44; 51–54; 61) in the volume under investigation (10) extend substantially parallel to this outer surface (9) thereby producing an NMR transmitting and receiving apparatus with improved properties, in particular, one permitting precise influence of the distribution of the RF-B1 field.

Abstract: The invention relates to a glass ceramic mass containing at least one oxide ceramic containing barium, titanium and at least one rare earth metal Rek; and at least one glass material containing at least one oxide with boron, at least one oxide with silicon and at least one oxide with at least one bivalent metal Me2+. The glass ceramic mass is characterised in that the glass material contains at least one oxide with bismuth, especially bismuth trioxide. The oxide ceramic is especially a microwave ceramic of formula BaRek2Ti4O12, Rek being neodymium or samarium. The composition of the oxide ceramic remains essentially constant during the sintering of the glass ceramic, enabling the material properties of the glass ceramic mass, such as permittivity (20–80), quality (800–5000) and Tkf (±20 ppm/K) to be specifically predetermined. The glass ceramic mass is characterised by a densification temperature of under 910° C.

Abstract: A force transducer is inserted into a small boring inside a test object. Inside the boring, it can measure the elastic extensions caused by the surrounding stress matrix. The force transducer is provided in two parts. Both parts are provided with a conical inner boring or conical outer periphery in such a manner that they can be held inside the boring of the test object by a tractive force. In order to span a large tolerance zone, the outer part is axially provided with multiple slits on both sides. The outer part is provided with a polygonal shape and thereby detects the deformations to be measured, not over the entire periphery, but it records theres via the contacts axially oriented through the axial lines. The extension is integrated in a peripheral direction between the contacts and is transferred into the inner part.

Abstract: The invention refers to a material which is chemically long-term stable in a neutral or slightly acid environment and which can be used both as bioactive bone replacement material, e.g. in the form of a coating applied onto metallic prosthesis sticks by thermal spraying, and as substrate material in biotechnology, e.g. in the form of a ceramic sheet. According to the invention, said material comprises 15-45% by weight CaO, 40-45% by weight P2O5, 10-40% by weight ZrO2 and fluoride, said material further comprises two crystalline phases being apatite and calcium zirconium phosphate, and a secondary glass phase. Said material has a very high chemical long-term stability, compared to known materials which can also be produced by means of a melting process.

Abstract: A method for evaluating measured periodic or quasiperiodic signals of medical sensor systems. The method comprises digitizing the measured signals with a specific first sampling frequency, normalizing the periods of the measured signals to a predetermined period length, using a database in which previously measured signals are stored after digitization with specific second sampling frequencies and in which medical findings are assigned to the stored signals. If the first and second sampling frequencies are not identical, converting the measured signal of the signals stored in the database so as to have the same sampling frequencies.
