A continuous, non-invasive fetal heart rate measurement is produced using one or more ultrasonic transducer array patches that are adhered or attached to the mother. Each ultrasound transducer array is operated in an autonomous mode by a digital signal processor to obtain data from which fetal heart rate information can be derived. Each ultrasonic transducer array patch comprises a multiplicity of subelements that are switchably reconfigurable to form elements having different shapes, e.g., annular rings. Each subelement comprises a plurality of interconnected cMUT cells that are not switchably disconnectable. The use of cMUT patches will provide the ability to interrogate a three-dimensional space electronically (i.e. without mechanical beam steering) with ultrasound, using a transducer device that is thin and lightweight enough to stick to the patient's skin like an EKG electrode. The ultrasound device can track the fetal heart in three-dimensional space as it moves due to the mother's motion or the motion of the unborn child within the womb.

The present disclosure provides methods for determining the ploidy status of a chromosome in a gestating fetus from genotypic data measured from a mixed sample of DNA comprising DNA from both the mother of the fetus and from the fetus, and optionally from genotypic data from the mother and father.

Systems, methods, and apparatuses can determine and use methylation profiles of various tissues and samples. Examples are provided. A methylation profile can be deduced for fetal / tumor tissue based on a comparison of plasma methylation (or other sample with cell-free DNA) to a methylation profile of the mother / patient. A methylation profile can be determined for fetal / tumor tissue using tissue-specific alleles to identify DNA from the fetus / tumor when the sample has a mixture of DNA. A methylation profile can be used to determine copy number variations in genome of a fetus / tumor. Methylation markers for a fetus have been identified via various techniques. The methylation profile can be determined by determining a size parameter of a size distribution of DNA fragments, where reference values for the size parameter can be used to determine methylation levels. Additionally, a methylation level can be used to determine a level of cancer.

Methods, apparatuses, and system are provided for analyzing a maternal sample to determine whether a male fetus of a pregnant female has inherited an X-linked mutation from the mother. A percentage of fetal DNA in the sample is obtained, and cutoff values for the two possibilities (fetus inherits mutant or normal allele) are determined. A proportion of mutant alleles relative to a normal allele on the X-chromosome can then be compared to the cutoff values to make a classification of which allele is inherited. Alternatively, a number of alleles from a target region on the X-chromosome can be compared to a number of alleles from a reference region on the X-chromosome to identify a deletion or amplification. The fetal DNA percentage can be computed by counting reactions with a fetal-specific allele, and correcting the number to account for a statistical distribution among the reactions.
