  • Publication number: 20160166195
    Abstract: The present invention relates to the area of lifestyle devices and applications, particularly to daily trackers of activities, such as pedometers used for exercise monitoring, and working in collaboration with tools analyzing and planning the food intake and amount of exercises to keep or obtain the desired weight. This invention aims at better controlling: fitness level, food consumption, blood glucose level and weight of a person throughout the day. For daily and weekly tracking of the weight, the ingested and expended calories are reported. Calories meal goals are adjusting daily reflecting the over the goal exercise levels as well as mismatch in food consumed and meal goals. The method for better blood glucose control predicts the effects of the food ingested on raising a post-meal blood glucose level, and suggests a suitable timing and the duration of the exercise following the food intake to minimize a post-meal blood glucose peak.

  • Publication number: 20160166205
    Abstract: This invention relates to a system that adaptively compensates for subject motion in real-time in an imaging system. An object orientation marker (30), preferably a retro-grate reflector (RGR), is placed on the head or other body organ of interest of a patient (P) during a scan, such as an MRI scan. The marker (30) makes it possible to measure the six degrees of freedom (x, y, and z-translations, and pitch, yaw, and roll), or “pose”, required to track motion of the organ of interest. A detector, preferably a camera (40), observes the marker (30) and continuously extracts its pose. The pose from the camera (40) is sent to the scanner (120) via an RGR processing computer (50) and a scanner control and processing computer (100), allowing for continuous correction of scan planes and position (in real-time) for motion of the patient (P).

  • Publication number: 20160166206
    Abstract: In embodiments, an external medical device is intended to care for a patient. If it receives an input that signifies that ventilation artifact is present in a signal of the patient, it transmits a corrective signal responsive to the received input. In further embodiments, a patient signal is received, which is generated from a patient while the patient is or was receiving chest compressions at a frequency Fc, and also receiving ventilations at frequency Fv. At least one filter mechanism may be applied to the patient signal to substantially remove artifacts at a) frequency Fc, b) a higher harmonic of frequency Fc, and c) a third frequency substantially equaling frequency Fc plus or minus frequency Fv, while substantially passing other frequencies between them. As a result, the patient signal can be cleaner, for diagnosing the patient's state more accurately.

A CT system with maximum fan-angle ? and K simultaneously active x-ray sources distributed over an angle of ?-2? radians, the sources partially overlapping on a detector array, measures summed projection data corresponding to K or less line-integrals at each detector element. When the CT machine's dimensions RM, Rd, and RS, corresponding respectively to the measurement field-of-view, detector distance from iso-center, and source distance from iso-center, are such that projections of the two extreme radiation sources do not overlap on the detector, the individual line-integrals can be recovered by inversion of linear systems comprising K or less rows in fewer unknown than rows; the unknowns given by the exponential of the negative of the line integrals to be recovered. The CT scanner then reconstructs an image from the line-integral estimates.

    Abstract: Systems and methods are described for determining a minimum radiation dose for a computed tomography (CT) scanning device. The method includes receiving a first input indicative of a selected minimum detectable contrast and a second input indicative of an estimate of a size of a subject to be exposed to the radiation dose. A minimum radiation dose to be applied via a radiation source is determined. The minimum radiation dose is determined at least in part by a power law model relating the size of the subject, a lesion size, and a minimum detectable contrast. The power law model is defined as MDC=A(L) dB(L) DoseC(L), wherein (i) MDC is the selected minimum detectable contrast, (ii) d is lesion size, (iii) Dose is radiation dose, (iv) A(L), B(L), and C(L) are pre-determined fitted parameters, and (v) L is the estimate of the size of the subject.

    Abstract: The present invention pertains to an apparatus and method for adaptive exposure in imaging systems. An x-ray source for producing x-ray radiation and an x-ray detector for measuring amount of x-ray radiation passing through the human patient and striking the detector can be used. A tomographic image of the human patient or a tomosynthetic image of the human patient can be generated. Region of interest filtering and equalization filtering can be utilized. Filtering can be accomplished with a mechanical shield or shutter or with electronic control of the x-ray source.

  • Publication number: 20160166226
    Abstract: The invention relates to a method for producing an x-ray image (1) of an object (2) by means of an x-ray device (3). An x-ray source (4) and an x-ray detector (5) are moved about an object (2) during an at least partial circulation (8, 9), and the x-ray beams (10) which are generated by the x-ray source (4) and pass through the object (2) are detected from multiple different directions by means of the x-ray detector (5). In the process, at least one optical camera (13, 14) captures the object (2) during the circulation, wherein an optical image (15, 17) is produced. The optical camera (13, 14) has a rigidly defined position relative to the x-ray source (4) and/or the x-ray detector (5). The optical image (15, 17) is then used to determine a movement trajectory of the object (2) relative to the x-ray source (4) and/or the x-ray detector (5).

    Abstract: A method for correcting rotation speed of a rotatable gantry in a CT scanner system is provided. The method may include: detecting an actual rotation speed of the rotatable gantry; determining a deviation percentage of the actual rotation speed from an instructed rotation speed sent to the rotatable gantry; and if the deviation percentage is smaller than a first preset threshold and larger than a second preset threshold, correcting the instructed rotation speed according to the deviation percentage.

    Abstract: A computer-implemented method for correcting measurement variability across a scanner field of view within an image scan, such as in PET imaging. The method operates on a slice-by-slice application and identifies and negates scan inconsistencies across the scanner field of view by normalizing values across the image scan as a function of reference signals measured across the field of view.

  • Publication number: 20160166231
    Abstract: The present invention relates to a monitoring apparatus (100, 200) for monitoring a structural change in an object (280, 340), such as a heart wall tissue. Tissue at first and second locations exhibits first and second velocities. The monitoring apparatus (100, 200) comprises an ultrasound signal providing unit for providing ultrasound signals of the object (280, 340) for different times. The monitoring apparatus (100, 200) further comprises a discontinuity determination unit (120, 220) for determining a discontinuity of the first and second velocities based at least in part on a change in time of tissue velocity differences and of tissue velocity sums. From the discontinuity an ablation depth can be determined, which is an important parameter while performing an ablation procedure. For example, it can be used for determining the progress of ablation within the object and for determining when the ablation has reached a desired dimension.

  • Publication number: 20160166235
    Abstract: A method and apparatus are disclosed for integrating optical coherence tomography (OCT) and very high frequency ultrasound (VHFU) imaging systems. An OCT probe and reference arm are mounted along with an ultrasound probe on a carriage capable of rotational, linear, and/or arcuate motion. The probe carriage may be immersed in water or other suitable medium. The OCT and VHFU probes move about the cornea surface such that the probe axes are substantially perpendicular relative to the cornea surface throughout a scan. The probes are able to be scanned in an arcuate path across the entire cornea surface. The method and apparatus disclosed are also directed towards providing a positioning mechanism and scan head comprising an arcuate guide track wherein only an OCT probe is mounted on the probe carriage. This embodiment allows the OCT probe beam to remain substantially perpendicular to the cornea and lens surfaces.
