  • Patent number: 11375914
    Abstract: A method for producing an image representative of the vasculature of a subject using a MRI system includes the acquisition of a signal indicative of a subject' cardiac phase. During each heartbeat of the subject, image slices of a volume covering a region of interest (ROI) within the subject are acquired by applying a volume-selective venous suppression pulse to suppress (a) venous signal for an upper slice in the ROI; (b) venous signal for slices that are upstream for venous flow in the ROI; and (c) background signal from the upstream slices. Next, a slice-selective background suppression pulse is applied to suppress background signal of the upper slice. Following a quiescent time interval, a spectrally selective fat suppression pulse is applied to the entire volume to attenuate signal from background fat signal. Then, a simultaneous multi-slice acquisition of the upper slice and the upstream slices is performed.

  • Patent number: 11328185
    Abstract: A system and method for performing speckle correlation flow cytometry (SCFC). By subtracting out the stationary background when shining light through a sample (e.g., a vessel within a biological tissue), light only scattered by the desired targets (e.g., cells) can be captured and different types of targets (e.g., cells) can be distinguished by the autocorrelation of the speckle pattern. In this way, the targets (e.g., cells) can be classified and counted based on the features of their speckle correlations. The technique can be applied not only for noninvasive, label-free, in vivo CTC counting but also for counting other types of blood cells such as white blood cells or red blood cells.

  • Patent number: 11317896
    Abstract: An ultrasound diagnosis apparatus includes a calculating unit, an obtaining unit, a determining unit, and a controlling unit. By using a plurality of pieces of three-dimensional ultrasound image data in a time series corresponding to a three-dimensional region including a myocardium of a subject, the calculating unit calculates first movement information indicating a movement of the myocardium by tracking a movement of a region of interest that corresponds to the myocardium and that is set in each of the plurality of pieces of three-dimensional image data. The obtaining unit obtains direction information indicating a direction of a myocardial fiber in the myocardium. The determining unit determines second movement information indicating a movement of the myocardium with respect to the direction of the myocardial fiber, on the basis of the first movement information and the direction information. The controlling unit causes a display unit to display the second movement information.

  • Patent number: 11284910
    Abstract: A therapeutic ultrasound system transmits a staggered or interleaved pattern of therapy beams for use in sonothrombolysis and other Vascular Acoustic Resonators (VAR) mediated therapy. The inventive technique minimizes VAR, e.g. microbubble, destruction due to adjacent beams, ensures uniform sonication of the targeted region by filling in the spaces between the beams in subsequent passes, and further provides a means for bubble replenishment to maximize the clot lysis from ultrasound. The technique is also applicable to diagnostic ultrasound, VAR mediated drug delivery and blood brain barrier opening.

  • Patent number: 11138734
    Abstract: A hyperspectral facial analysis system and method for personalized health scoring to assess the risk that a person has a disease. Embodiments capture images in multiple spectral bands, such as visible, infrared, and ultraviolet, and analyze these images to generate multiple health metrics, such as pallor, temperature, sweat, and chromophores. These metrics may be combined into an overall health score that may be used for screening. Image analysis may focus on the area under the eyes, where skin is thinnest. Images may be compared to a reference population to identify anomalous values, so that health scoring automatically adjusts for local conditions. Pallor may be calculated based on hue and saturation of visible light images. Temperature may be calculated based on infrared image intensity. Sweat may be calculated using cross-polarized images to identify specular highlights. Chromophores may be calculated by comparing frequency domain ultraviolet images to those of the reference population.
