    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.

    摘要: 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 method for determining positron emission measurement information in the context of positron emission tomography is disclosed. The method includes using a marker substance to carry out a positron emission measurement, in a body area of a subject to be examined, to determine positron emission measurement information, and at the same time, generating images of the body area to be examined by way of a second medical method with a time resolution suitable for determining perfusion and/or diffusion information. The method further includes using the images from the second method to determine perfusion and/or diffusion information for at least a part of the measurement period, and evaluating the positron emission measurement information as a function of the perfusion and/or diffusion information.
