  • Patent number: 10413257
    Abstract: An apparatus for collecting super-sampled imaging data includes an imaging scanner, a bed, and a first motor. The imaging scanner includes a plurality of detectors arranged substantially circumferentially about a scanner axis. The bed has a plane and a central axis that is generally in the plane of the bed. However, the bed is oriented so as to form a first non-zero degree angle between the central axis and the scanner axis. The first motor translates the bed along the central axis, and a second motor may translate the bed along an axis orthogonal to the central axis and scanner axis. Since the voxels pass through the scanner in different relative positions of the bed, additional information may be acquired during the scan.

  • Patent number: 10363012
    Abstract: An ultrasonic diagnostic imaging system is described which utilizes one or more transducer arrays affixed to the head of a patient to diagnose and treat stroke victims. The transducer headset produces a two or three dimensional image of the vasculature inside the cranium, preferably assisted by a microbubble contrast agent. A vascular flow map is produced by the system which may be diagnosed for signs of a blood clot. If a blood clot is detected, a therapeutic beam is transmitted while the contrast agent is present to break up the blood clot by the disruption of microbubbles. The headset may also be used in a monitoring application to detect the recurrence of blood clots in a stroke victim.

  • Patent number: 10357181
    Abstract: Provided is a method of analyzing brain activities for realizing a biomarker for neurological/mental disorder, based on brain function imaging. From measured data of resting-state functional connectivity MRI of a healthy group and a patient group, correlation matrix (80) of degree of brain activities among prescribed brain regions is derived for each subject. Feature extraction is executed by regularized canonical correlation analysis (82) on the correlation matrix (80) and attributes of the subject including a disease/healthy label of the subject. Based on the result of regularized canonical correlation analysis, by discriminant analysis (86) through sparse logistic regression, a discriminator (88) is generated.
