The present invention relates to method for assisting a user in generating an itemised medical report from at least one medical image. The at least one medical image is displayed in a display area of single computer display unit. In the same display area, a sub-region containing a checklist specific to the one or more images is displayed. Items from the checklist can be de-selected. This checklist comprises a list of selectable items, each item representing an organ, structure, or abnormality that has to be checked by the user. Linked to each item in the checklist is a default statement that is a pre-prepared statement indicative of the normality of the item. The default statement is not displayed by default as part of the checklist. The user can select an item from the checklist for providing comments by dictation thereon responsive to an observation in the radiological image. At the end of the image analysis, an editable itemised medical report is generated containing each item of the checklist as a heading and either the dictated comment or the default statement associated with the item as an observation. The editable itemised medical report is rapidly and accurately generated, information is confined to a single screen reducing the look-away time and general discomfort over time for the user.

Related free-text documents, a corpus, are used to empirically derive a semantic knowledge base through a method in which documents are segmented into unique sentences, and then used to define sentential propositions which are arranged in a knowledge hierarchy. The method takes compound natural language sentences and transforms them to simple sentences by a process that is a part of the invention. A knowledge editor enables a domain expert using the methods of the invention to map the sentences in the corpus to sentential proposition(s). The resulting knowledge base can be used to semantically analyze documents in data mining and decision support applications, and can assist word processors or speech recognition devices. The invention is illustrated in connection with radiology reports, but it has wide applicability.

In a method for the obtaining a tomosynthesis image for a more selective detection of radiology signs, a dose distribution strategy is proposed. The strategy is defined as a function of a substantially uniform depth-of-focus for a variety of sizes and classes of radiology signs. This strategy is coupled with a digital filtering aimed at ensuring optimum propagation of the signal-to-noise ratio beyond the frequency spectrum. This digital filtering is done by means of a class of adaptive filters required to control the propagation of the noise during the reconstruction. The filter to be applied to each projection of the X-ray tube (4) depends on the dose assigned to this projection.
