  • Patent number: 11826188
    Abstract: The present disclosure relates to a medical imaging system having an X-ray source, a detector and a processing system. The the X-ray source is collimated to produce a diverging beam of radiation and transmits X-rays through an object. The detector includes detector pixels arranged in at least one row and is operative to receive the X-ray energy of the X-rays after having passed through the object. The processing system is programmed to select an initial height of the object with respect to the X-ray source plane and determine an initial time delayed summation (TDS) shift frequency based on the initial height. The processing system performs a first scan of the object based on the TDS shift frequency and determines a new height of the object based on a beam angle and an overlap of adjacent images. A new TDS shift frequency is determined based on the new height of the object if the initial height and the new height are not substantially same.

  • Patent number: 11445269
    Abstract: Advertisements are tailored not only to a person's profile but also to the context in which the person finds himself. Thus, for example a video-based advertisement may be reformatted or reprovisioned in audio format when the person is driving, while an audio-based advertisement may be reformatted or reprovisioned to video format in noisy conditions.

  • Patent number: 11123034
    Abstract: An imaging system includes radiation source that emits radiation that traverses an examination region and a portion of a subject therein and a detector array that detects radiation that traverses the examination region and the portion of the subject therein and generates a signal indicative thereof. A volume scan parameter recommender recommends at least one spectral scan parameter value for a volume scan of the portion of the subject based on a spectral decomposition of first and second 2D projections acquired by the radiation source and detector array. The first and second 2D projections have different spectral characteristics. A console employs the recommended at least one spectral scan parameter value to perform the volume scan of the portion of the subject.

  • Patent number: 9717415
    Abstract: Apparatus and methods are described including inserting a tool into a blood vessel, and, while the tool is within the blood vessel, acquiring an extraluminal image of the blood vessel. In the extraluminal image of the blood vessel, a location of a portion of the tool with respect to the blood vessel is detected automatically. In response to detecting the location of the portion of the tool, a target portion of the blood vessel that is in a vicinity of the portion of the tool is designated automatically. Using the extraluminal image, quantitative vessel analysis is performed on the target portion of the blood vessel. Other embodiments are also described.
