Abstract: The invention concerns an X-ray detection device, comprising: a semiconducting X-ray detecting member provided with first and second electrode contacts; first and second electric wires connected to the first and second electrode contacts, respectively; a dose adjusting element comprising tissue equivalent material, wherein the dose adjusting element is arranged such as to surround the detecting member with tissue equivalent material; and a shielding member configured to provide an electric shield for the detecting member and to protect the detecting member from being exposed to light. The invention is characterized in that the first electrode contact is positioned on the same side of the detecting member as the second electrode contact.

Abstract: A method for determining alignment of light and an X-ray fields of an X-ray apparatus, comprising: directing the light field onto an exposure area, positioning a scale and an X-ray indicating element in association with each other at the exposure area such that said scale and X-ray indicating element cross an edge of the light field, wherein said X-ray indicating element emits light upon exposure to X-rays so that parts exposed to X-rays can be distinguished from non-exposed parts, determining a position on the scale where the light field edge is positioned, and directing the X-ray field onto the exposure area. The method comprises generating an image of the scale and the X-ray indicating element using a digital camera, determining a position on the scale where an edge of the X-ray field is positioned, and comparing the scale positions of the edges of the light and X-ray fields.

Abstract: A simplified method and a device to determine the size and/or the location of focus of an X-ray tube. By means of a slit camera a longish image of the extension of the focal spot is achieved in one direction, the image of which normally is recorded photographically and can be analyzed by a microdensitometer. This is a time-consuming and circumstantial procedure, which normally requires many exposures. According to the invention a slit image is utilized in the same manner as in the slit-camera but instead of a photographic film for the recording one uses a line sensor with its sensor elements being arranged parallel to the slit and at least cover the width of the slit image in question. With this arrangement a pronounced electric signal from a single exposure is obtained due to that each line sensor element detects the signal from sections across the slit along the whole length of the sensor.
