Provided are a method and a ultrasound imaging apparatus for managing growth of follicles in an ovary where the method comprises detecting, by a signal processor, the follicles and a plurality of parameters associated with each follicle in a three dimensional (3D) ultra sound image, tracking the detected follicles in a longitudinal scan, monitoring a rate of growth of each follicle based on the detected parameters in the longitudinal scan, determining a dosage of hormone for stimulating the ovary based on the rate of growth of each follicle, and generating a report and a nomograph based on the rate of growth of each follicle.

An ultrasonic imaging system is described which visually assists biopsy needle insertion. The system produces pixel values of pixels along one or more paths of needle insertion. A tissue density analyzer is responsive to the pixel values to estimate tissue density along a path of needle insertion. A needle path calculator is responsive to the tissue density analyzer and proposes one or more favorable paths through imaged tissue for insertion of the biopsy needle. The system may be used in conjunction with a three dimensional navigation system which spatially locates the needle and ultrasound image plane in 3D space.

Signal processing devices normally filter the signal to reduce noise. Any filtering is likely to eliminate useful components of the signal too. A device for and method of signal processing is disclosed, wherein intrinsically clean signal cycles are selected for reproduction so that the processed signal retains components of all frequencies. A system that uses the disclosed device and the method for processing periodic physiological signals is also disclosed.

Processing of periodic physiological signals

An analyte measuring device () for monitoring, for example, levels of a tissue analyte (e.g., bilirubin), includes a number of narrow band light sources (), each narrow band light source being structured to emit a spectrum of light covering a number of wavelengths, and a number of detector assemblies () configured to receive light reflected from the transcutaneous tissues of a subject. Each of the detector assemblies includes a filter () and a photodetector (), each filter being structured to transmit a main transmission band and one or more transmission sidebands, wherein for each narrow band light source the spectrum thereof includes one or more wavelengths that fall within the transmission band of at least one of the filters, and wherein for each narrow band light source the spectrum thereof does not include any wavelengths that fall within the one or more transmission sidebands of any of the optical filters.

A tissue analyte measuring device () includes a light source () structured to emit unpolarized light toward the skin surface of a subject, and a detector assembly () configured to receive light reflected from the skin surface of the subject and the transcutaneous tissues of the subject, the detector assembly including a polarizing filter () and a number of light detector subassemblies (). The polarizing filter is structured to filter out s-polarized light and pass only p-polarized light to light detector subassemblies. The light source is structured and positioned to emit the unpolarized light in a manner wherein the unpolarized light will exit the measuring device at a predetermined angle with respect to a normal to a light emitting plane of the measuring device, wherein the predetermined angle is an angle (the Brewster's angle) at which only s-polarized light will be reflected by the skin surface when the unpolarized light is incident thereon.

A bilirubin measuring apparatus includes a sample holding portion for holding at least a sample to be analyzed, a light source for directing light toward the sample holding portion, and means for determining a concentration of bilirubin in the sample based on an amount which the light is refracted while passing through the sample holding portion when at least the sample is held at the sample holding portion. Also, a method of measuring bilirubin in a sample includes holding at least the sample at a sample holding position, directing light toward the sample holding position so that the light will pass through the sample, and determining a concentration of bilirubin in the sample based on an amount which the light is refracted while passing through the sample holding position.
