Patent Issued for Rules-Based Approach to Transferring And/Or Viewing Medical Images

May 14, 2014



By a News Reporter-Staff News Editor at Journal of Engineering -- A patent by the inventors Reicher, Murray A. (Rancho Santa Fe, CA); Fram, Evan K. (Paradise Valley, AZ), filed on September 27, 2010, was published online on April 29, 2014, according to news reporting originating from Alexandria, Virginia, by VerticalNews correspondents.

Patent number 8712120 is assigned to DR Systems, Inc. (San Diego, CA).

The following quote was obtained by the news editors from the background information supplied by the inventors: "This disclosure relates to transferring and/or viewing of medical images

"Medical imaging is increasingly moving into the digital realm. This includes imaging techniques that were traditionally analog, such as mammography, x-ray imaging, angiography, endoscopy, and pathology, where information can now be acquired directly using digital sensors, or by digitizing information that was acquired in analog form. Many imaging modalities are inherently digital, such as computed radiography (CR), digital radiography (DR), MRI (magnetic resonance imaging), CT (computed tomography), PET (positron emission tomography, NM (nuclear medicine scanning), FFDM (full-field digital mammography), and US (ultrasound), often yielding hundreds or even thousands of images per examination. Increasingly these digital images are viewed, manipulated, and interpreted using computers and related computer equipment. Accordingly, improved systems and methods are needed for distributing, viewing, and prioritizing these digital images under various network and viewing conditions."

In addition to the background information obtained for this patent, VerticalNews journalists also obtained the inventors' summary information for this patent: "In one embodiment, a method of selecting medical images of an image series for transfer comprises, by a computing device executing software, performing operations comprising, accessing transfer criteria associated with a first computing device, the transfer criteria indicating thin slice criteria for determining whether respective medical images of an image series are classified as thin slices, wherein the thin slice criteria include at least one of a maximum thickness of a particular medical image for classification of the particular image as a thin slice image or a maximum quantity of medical images in the image series for classification of the medical images of the image series as thin slice images, selecting a first group of medical images of the image series that are thin slice images as indicated by the thin slice criteria, initiating transfer of the first group of medical images to the first computing device, wherein medical images of the image series that are not in the first group are not transferred to the first computing device.

"In one embodiment, a method comprises, by a computing device comprising hardware, performing operations comprising accessing thin slice criteria for determining whether respective medical images of an image series are classified as thin slices, selecting a thin slice series of medical images that includes one or more medical images that are classified as thin slices based on the thin slice criteria, selecting a non-thin slice series of medical images that includes one or more medical images that are not thin slice images based on the thin slice criteria, and transferring or displaying the thin slice series in a different manner than the non-thin slice series, such that either the images of the thin slice series are selectively not transferred, selectively transferred with lower priority, selectively transferred but not displayed, or selectively transferred but otherwise displayed or processed in a selectively different manner.

"In one embodiment, a tangible computer readable medium has instructions stored thereon, wherein the instructions are configured for reading by a computing device in order to cause the computing device to perform operations comprising accessing transfer criteria associated with a first computing device and a first user, the transfer criteria indicating thin slice criteria for determining whether respective medical images of an image series are classified as thin slice images, wherein the thin slice criteria include at least one of a maximum thickness of a particular medical image for classification of the particular image as a thin slice image or a maximum quantity of medical images in the image series for classification of the medical images of the image series as thin slice images, selecting a first group of medical images of an image series that are not thin slices as indicated by the thin slice criteria, and initiating transfer of the first group of medical images to the first viewing environment, wherein medical images of the image series that are not in the first group are not transferred to the first viewing environment.

"In one embodiment, a method comprises by a computing device configured for displaying medical images, determining a storage location of a dataset, determining an availability of a processing server to process the dataset, in response to determining that the dataset is locally available to a processing server configured to process the dataset, requesting processing of the dataset by the processing server and accessing the processed dataset from the processing server, and in response to determining that the dataset is not locally available to the processing server and/or the processing server is not available to process the dataset, requesting transmission of at least some of the dataset to the computing device and processing the at least some of the dataset at the computing device."
