摘要:
A method is disclosed for normalizing the results of an in-vitro analytical method for one or more diagnostically and/or prognostically relevant substances in an organism (biomarker) or one or more substances supplied to an organism from the outside. In at least one embodiment of the method a) one or more concentration values of the substance(s) in an organism, said concentration value(s) being obtained in an in-vitro analytical method is (are) provided, b) data obtained from an imaging study of the same organism are provided, c) from the data according to b), one or more quantitative values are determined as imaging value(s), d) from the values according to a) and c), one or more diagnostic parameters are determined by relating the values according to a) and c) to one another, and also to the use of this method for the type-correct dosage finding of drugs and for the in-vitro diagnosis, prognosis and monitoring the course of a disease. In addition, at least one embodiment of the invention relates to a program for a data processing system which, when carried out in a suitable computer system, carries out the above method, and also to an electronically readable data carrier having electronically readable control information stored thereon, which control information is configured in such a manner that they carry out the above method when a suitable data carrier is used in a suitable computer system.
摘要:
A material layer on a substrate being processed, e.g. to form chips, includes one or more functional structures. In order to control pattern density during fabrication of the chip, dummy fill structures of different sizes and shapes are added to the chip at different distances from the functional structures of the material layer. In particular, the placement, size and shape of the dummy structures are determined as a function of a distance to, and density of, the functional structures of the material layer.
摘要:
An apparatus, system and method to compensate for the proximity effects in the imaging of patterns in a photolithography process. A light exposure of a photoresist layer is effectuated in predetermined patterns through an exposure mask having light-transmissive openings in correspondence to the predetermined patterns. The exposure mask has areas densely populated with the light-transmissive openings and areas sparsely populated with the light-transmissive openings. Light is attenuated through the densely populated light-transmissive openings by a different amount than through the sparsely populated light-transmissive openings.

In a method to determine a kidney function parameter of kidneys of an examination person with the aid of magnetic resonance tomography, at least one magnetic resonance measurement is implemented for an examination region of the examination person that comprises a urinary bladder of the examination person, to acquire magnetic resonance data from the examination region that include at least image data. The concentration of a urophanic substance in the urinary bladder of the examination person is automatically determined based on the acquired magnetic resonance data. A volume of the urinary bladder is automatically determined based on the acquired image data. A kidney function parameter of the kidneys of the examination person is automatically determined on the basis of the determined concentration of the urophanic substance in the urinary bladder and of the specific volume of the urinary bladder.

摘要:
A combined PET/MRI tomography unit has a PET unit with a unit part assigned to the examination space, and a first evaluation unit for evaluating the PET electric signals. The unit part has a gamma ray detector. The combined unit has an MRI unit and a second evaluation unit for evaluating MRI signals. The MRI unit has a high frequency antenna as well as a gradient coil system, the high frequency antenna device being arranged nearer to the examination space than the gradient coil system, as well as a high frequency shield arranged between the gradient coil system and the high frequency antenna device. The PET unit part is arranged between the high frequency shield and the high frequency antenna device. A shielding cover for the high frequency antenna device faces the high frequency antenna device. The shielding cover is opaque to high frequency radiation.

A method and an apparatus for imaging functional and electrical activities of the brain are disclosed. In order to allow improved relative positional determination of the epileptogenic focus with reference to the EEG electrodes, a positron emission tomography measurement using at least one radiation detector, and a magnetic resonance imaging measurement using at least one coil for generating a basic magnetic field, at least one gradient coil and a radio-frequency antenna device are undertaken in at least one embodiment. In addition, in at least one embodiment an electroencephalography measurement using a plurality of electrodes for acquiring spatial and temporal changes of the electrical activities of the brain and a computed tomography measurement using at least one x-ray source and at least one x-ray detector are carried out. By way of an evaluation apparatus in at least one embodiment, a spatial correlation between the computed tomography measurement and the magnetic resonance imaging measurement is undertaken, so as to result in registration between the electroencephalography measurement and the positron emission tomography measurement.
