  • Patent number: 10674935
    Abstract: A method of obtaining information about the position and/or orientation of a magnetic component relatively to a magnetometric detector, the magnetic component and the magnetometric detector being moveable independently from each other relatively to a static secondary magnetic field, the method comprising the steps of: measuring in the presence of the combination of both the magnetic field of the magnetic component and the static secondary magnetic field essentially simultaneously the strength and/or orientation of a magnetic field at at least a first position and a second position spatially associated with the magnetometric detector, the second position being distanced from the first position; and combining the results of the measurements to computationally eliminate the effect of the secondary magnetic field and derive the information about the position and/or orientation of the magnetic component.

  • Patent number: 10667718
    Abstract: Example embodiments associated with characterizing a sample using NMR fingerprinting are described. One example NMR apparatus includes an NMR logic that repetitively and variably samples a (k, t, E) space associated with an object to acquire a set of NMR signals that are associated with different points in the (k, t, E) space. Sampling is performed with t and/or E varying in a non-constant way. The NMR apparatus may also include a signal logic that produces an NMR signal evolution from the NMR signals and a characterization logic that characterizes a tissue in the object as a result of comparing acquired signals to reference signals. Example embodiments facilitate distinguishing prostate cancer tissue from normal peripheral zone tissue based on quantitative data acquired using NMR fingerprinting in combination with apparent diffusion co-efficient (ADC) values or perfusion values acquired using DWI-MRI or DCE-MRI.

  • Patent number: 10646159
    Abstract: Dual-energy absorptiometry is used to estimate visceral fat metrics and display results, preferably as related to normative data. The process involves deriving x-ray measurements for respective pixel positions related to a two-dimensional projection image of a body slice containing visceral fat and subcutaneous fat, at least some of the measurements being dual-energy x-ray measurements, processing the measurements to derive estimates of metrics related to the visceral fat in the slice, and using the resulting estimates. Processing the measurements includes an algorithm which places boundaries of regions, e.g., a large “abdominal” region and a smaller “abdominal cavity” region. Two boundaries of the “abdominal cavity” region are placed at positions associated with the left and right innermost extent of the abdominal muscle wall by identifying inflection of % Fat values.

  • Patent number: 10529097
    Abstract: In a method and apparatus for generating a three-dimensional multi-slice data set of a heart, a first image sequence with a number of two-dimensional images is acquired in a first slice of the heart during a duration of at least one heartbeat interval, and a second image sequence with a number of two-dimensional images is acquired in a second slice of the heart during the duration of a number of heartbeat intervals. The second image sequence is excised by selecting the two-dimensional images thereof that lie in a heartbeat interval closest to the duration of the heartbeat interval in the first slice. The three-dimensional multi-slice data set is generated by combining the first image sequence and the excised second image sequence.
