Manufacture of a Collimator Element

Simple SummaryContent extracted from patent full text and abstract with AI.

This patent describes a method for manufacturing a collimator element used in radiological imaging devices. The process involves applying and patterning a special lithographic coating, aligning structural features precisely, developing the pattern, and subsequently coating selective areas with an X-ray absorbing material to create an effective collimator structure. The main goal is to produce highly accurate collimators for use in scattered-radiation control, particularly in devices like CT scanners and radiation detectors.

Use CasesContent extracted from patent full text and abstract with AI.

• Production of collimators for medical CT (Computed Tomography) scanners
• Integration into advanced radiation detectors for more accurate imaging
• Use in manufacturing scattered-radiation collimators for X-ray and diagnostic imaging equipment

Patent Abstract

A method is disclosed for manufacturing a collimator element. The method includes applying a lithographic coating layer. The lithographic coating layer is then exposed using a grid mask. Exposure regions then correspond to a structure of the collimator element. Here, the structure of the collimator element is aligned on a common focus. The lithographic coating layer is then developed to give a pre-structure of the collimator element. Further, an X-ray absorbing layer is applied via cathode sputtering. At least the X-ray absorbing layer is then removed from regions of the pre-structure. A collimator element, a method for manufacturing a scattered-radiation collimator, a scattered-radiation collimator, a radiation detector and a CT device are also disclosed.
