  • Patent number: 9600882
    Abstract: A medical image navigation system (2) includes a viewport module (4), a proximity module (26), a visualization module (28) and a matching module (34). The viewport module (4) navigates a plurality of image slices of a study and based on input from at least one input device selects at least one image which is displayed and any annotations associated with the selected at least one image on a display device. The proximity module (26) for the selected image slice returns at least one proximate annotation, if available. The visualization module (28) for the returned at least one proximate annotation visualizes the at least one proximate annotation which is displayed by the viewport module on the selected at least one image. A matching module (34) retrieves for display an image slice in one study which corresponds to a displayed image slice from another study.

  • Publication number: 20160232329
    Abstract: When automatically populating medical report templates, insertable macros are indexed and searched not only my name or title but also by contents, such as keywords times, pre-defined terms for key information included in the macro, free texts in the macros, etc. When a unique macro is found, the system inserts the text of the macro into the report being generated. If multiple related macros are found, the system highlights the macros for user review. After the insertion of the macro into the template, the system identifies pre-defined terms and fills in the key information value(s). The system thus facilitates, e.g., radiologists' observation reporting procedure through an intelligent matching algorithm that facilitates finding a comprising keywords unique macro, which in turn aids in filling in report field instance values and optimizes radiology workflow.

  • Patent number: 9390236
    Abstract: As medical imaging becomes more affordable, and the diversity of diagnostic modalities and therapeutic treatments increase, the amount of data being stored increases, and the problem becomes even more critical. One approach to improve retrieval efficiency of images is to employ semantics to establish a defined set of search and classification terms. However, such semantic systems still require the user to make a selection of the most appropriate term or terms to classify a report or image, and the accuracy of the results are thus dependent on the skill and knowledge of the classifier. According to a first aspect of the invention, a retriever is provided for retrieving a medical image having a searchable attribute, the retriever being configured to interface with a semantic database and an image database, and wherein the searchable attribute is determined by segmenting the medical image, using the anatomical model.
