  • Publication number: 20100263672
    Abstract: A liquid container and a battery operated blower. The container with blower will go across the shoulder with any available strap. Blower will deliver the air in the container at the bottom of the liquid. Clean and decontaminated air will rise and exit through nasal cannula tube and deliver the clean air at the users nostrils. If the battery runs out the user will be able to connect the provided attachment to the nasal cannula and put the attachment inside the nostrils. Attachment is designed to let user breathe in and breathe out without the need to remove the attachment. Also an air regulator provided in so the flow of air can be regulated as per need of the user.

  • Patent number: 6922462
    Abstract: A method for plaque characterization. The method comprises obtaining a first set of image data created in response to a first x-ray energy level and including a plurality of pixel elements. Each of the first pixel elements corresponds to a unique location in an object being scanned. The method further comprises obtaining a second set of image data created in response to a second x-ray energy level and including a plurality of second pixel elements. Each of the second pixel elements corresponds to one of the first pixel elements and the second x-ray energy level is higher than the first x-ray energy level. The method also comprises calculating a third set of image data in response to the first set of image data and the second set of image data. The calculating includes subtracting each second pixel element from the corresponding first pixel element.

  • Publication number: 20050090737
    Abstract: A method for acquiring a cardiac image from a patient having a paced heart rhythm, an abnormal EKG, or an irregular heartbeat, is disclosed. A gated electrocardiogram signal having local maxima and minima values and trigger points is received. For a period of time, the time between each trigger point and the associated local maxima or minima is determined. In response to the trigger point occurring at the associated local maxima or minima, a zero time differential for a corrected trigger for gating is calculated, and in response to the trigger point not occurring at the associated local maxima or minima, a time differential for the corrected trigger for gating based on the time difference between the trigger point and the associated local maxima or minima is calculated.

  • Publication number: 20040017936
    Abstract: A method for calculating mass scores of calcium deposits. The method includes obtaining patient image data and identifying calcium plaque in the patient image data. The calcium plaque is associated with a plurality of discrete patient pixel elements and each of the patient pixel elements includes a patient pixel value expressed in Hounsfield units. The method also includes converting the patient pixel values into patient density values using a calibration curve equation and outputting the patient density values.

  • Patent number: 6597803
    Abstract: In one aspect, the present invention is a method for scanning an object with a multi-slice CT imaging system having multiple detector rows each having an isocenter. The method includes steps of helically scanning an object with the multi-slice CT imaging system to obtain data segments including peripheral data segments, combining data from a first peripheral data segment with an opposite, second peripheral segment to form a data set for reconstruction of an image slice; and reconstructing the combined data into image slices.

  • Patent number: 6298112
    Abstract: A method for producing a base tomographic image and a subsequent tomographic image of an object using projection data acquired in a scan with a system which includes an x-ray source and a detector array which includes a plurality of detectors. The method includes applying a segmentation algorithm to the projection data to generate base image data comprising a plurality of segments; generating image data for each segment; generate subsequent image data based on image data of each segment; and communicating image data, segments, subsequent image data, or base image data to a remote facility via a network. The remote facility provides remote services.

  • Patent number: 6075835
    Abstract: The present invention, in one form, is an imaging system which, in one embodiment, utilizes scan data and DAS input signals to determine image quality. More specifically, and in one embodiment, by generating a ratio of data from two scans, a group of non-conforming detector cells may be identified. In addition, by comparing scans performed at different time frames, a trend of image quality is also determined. In addition, a group of non-conforming DAS channels may be identified by applying a range of known input signals. By comparing the an absolute gain ratio, the DAS performance is determined.

  • Patent number: 6038278
    Abstract: The present invention, in one form, is a system for performing image reconstruction from projection data acquired in a helical scan. More specifically, the system implements an incremental reconstruction algorithm for helical scan projection data which does not require filtering, weighting and backprojecting such projection data for generating each image. Particularly, a segmentation algorithm divides the projection into a plurality of segments so that subsequent images are generated by generating image data only for those segments that have changed from the base image.
