Christopher Drexler has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8120613
    Abstract: The invention described in this application is an image file system for the acquisition and storage of streaming digital image data onto persistent storage media in real time and for full-rate playback of streaming digital image data stored on persistent storage media. Input/output of non-streaming digital image data is processed in system memory with write/read operations buffered by native operating system input/output support. Input/output of streaming digital data is processed in high-speed streaming digital image data I/O memory with write/read operations buffered by a high-performance image buffer thread.
    Type: Grant

  • Publication number: 20060092160
    Abstract: The present invention relates to a method for the rapid image processing of medical images, in particular fluoroscopic image recordings using image-modifying image processing algorithms on an image computer. With this method, a first part of the image processing algorithms is executed on a graphics processor of a graphics card and a second remaining part is executed on a master processor of the image computer. This division, for which standard hardware components are to be used, allows the omission of complex special developments of the hardware for the image computer.

  • Publication number: 20060087508
    Abstract: The invention relates to a method for the rapid image processing of two-dimensional images, in particular medical image recordings using image-modifying image processing algorithms, with which image processing is executed at least partially on a graphics card comprising at least one pixel shader unit and at least one vertex shader unit. With this method, the two-dimensional images are first transformed into three-dimensional representations, with which a first part of the image processing algorithms is executed on the vertex shader unit, and subsequently transformed back into two-dimensional representations, with which a second part of the image processing algorithms is executed on the pixel shader unit. The artificial generation of the three-dimensional representation from the two-dimensional images advantageously allows the vertex shader unit of the graphics card to be used for image processing, so that the computing capacity of the graphics card can be optimally utilized.
