Abstract: A spectrometer comprises a plurality of isolated optical channels comprising a plurality of isolated optical paths. The isolated optical paths decrease cross-talk among the optical paths and allow the spectrometer to have a decreased length with increased resolution. In many embodiments, the isolated optical paths comprise isolated parallel optical paths that allow the length of the device to be decreased substantially. In many embodiments, each isolated optical path extends from a filter of a filter array, through a lens of a lens array, through a channel of a support array, to a region of a sensor array. Each region of the sensor array comprises a plurality of sensor elements in which a location of the sensor element corresponds to the wavelength of light received based on an angle of light received at the location, the focal length of the lens and the central wavelength of the filter.

Abstract: The present invention relates to multi-dimensional filtering of ultrasound scan data for antialiasing or reconstruction for the purpose of re-sampling.

Abstract: The present invention relates to a method for planning an ultrasound guided biopsy of at least one region of interest in an organ comprising the steps of: a) obtaining backscattered 2D or 3D ultrasound data of a region of the organ, b) identifying one or more regions of interest in said three-dimensional volume using a first processor configured to analyze said 2D or 3D volume data, c) selecting in said first processor the characteristics of at least one ultrasound transducer suitable for the guidance of the biopsy comprising a biopsy needle, d) registering the transducer's characteristics selected in step (c) with the identified region of interest of step (b) using said processor, e) generating at least one biopsy scan plane image using the results of the registering step (d); and f) indicating on said simulated scan plane image the identified region of interest and at least one simulated needle trajectory. The present invention also relates to a method for performing ultrasound guided biopsy.

Abstract: The present invention relates to methods and systems for selecting and recording biopsy sites in a body tissue or organ. More in particular the present invention provides a method for selecting and recording biopsy sites in a body organ comprising: a) obtaining a three-dimensional volume of backscattered Ultrasound data grid of a three-dimensional region of the organ; b) obtaining a two-dimensional matrix of Ultrasound data of a two-dimensional sub-region of said organ; c) positioning the two-dimensional matrix of Ultrasound data in the three-dimensional volume of backscattered Ultrasound data grid obtained in step (a); d) optionally selecting one or more sites in the two-dimensional matrix of Ultrasound data where a biopsy is to be obtained; e) indicating in the three-dimensional volume of backscattered Ultrasound data grid and/or in the two-dimensional matrix of Ultrasound data any sites at which biopsies were obtained; and f) optionally repeating steps (b) to (e) as required.

Abstract: Analytical methods which are complementary to ultrasonic imaging systems and relate to the medical classification of human tissue as healthy or unhealthy (e.g. malignant) are disclosed. Methods and systems for the detection of abnormal tissue, in particular the characterization of tissue morphology which typifies a cancer process, are disclosed. The methods and systems are particularly applicable to ovarian cancer.

Abstract: A method and system for selecting and recording biopsy sites in a body organ. The method comprises obtaining a three-dimensional image of the organ; and a first two-dimensional sub-image of the organ. The position of the first two-dimensional sub-image in the three-dimensional image is determined. Sites in the first two-dimensional sub-image where a biopsy is to be obtained are selected, and sites at which biopsies were obtained are indicated in the three-dimensional image. Additional two-dimensional sub-images of the organ are sequentially obtained, and for each sub-image, the position of the sub-image in the three-dimensional image is determined, and any sites in the sub-image where biopsies have previously been obtained are indicated. One or more sites in the sub-image where biopsies are to be obtained are selected and any sites where biopsies were obtained are indicated in the three-dimensional image.

Abstract: A method and system for assessing a spatial regularity of reflecting members in a tissue. The method comprises irradiating the tissue and detecting waves reflected by the tissue. One or more parameters are then calculated, based upon the reflected waves, indicative of a degree of spatial disorder of reflecting members in the tissue.
