What is disclosed is a system and method for automatically segmenting a breast from surrounding tissue in a thermal image. A thermal image of at least one breast of the patient is received. The thermal image is then analyzed to identify a set of N points around the breast, a contour of an outline of the body, and isotherms of the axilla and infra-mammary fold. Thereafter, the points are connected together to form a N-sided irregular polygon which segments the breast from surrounding tissue. Each of the points is a vertex of the polygon and comprises a draggable object which enables a user to selectively manipulate a shape of the polygon. A user can add/delete vertices from the polygon as desired. The area of the image encompassed by the polygon is communicated to a breast cancer screening algorithm performing automated or semi- automated screening.

Die Erfindung betrifft ein Verfahren zur Kalibrierung mindestens einer 2D-Röntgenaufnähme (31) eines aufzunehmenden Objekts (2), die mittels eines Röntgengeräts (1) aufgenommen wurde, indem Röntgenstrahlen (3), die mittels einer Röntgenquelle (4) erzeugt werden, das Objekt (2) durchstrahlen und mittels eines Röntgendetektors (5) aufgenommen werden. Dabei wird ein bereits vorhandenes 3D-Modell (7) einer Struktur (6) des Objekts (2) mit der 2D-Röntgenaufnähme (31) verglichen, wobei eine tatsächliche Aufnahmelagebeziehung (15, 17) der Röntgenquelle (4) und des Röntgendetektors (5) relativ zum Objekt (2) und/oder relativ zueinander für die 2D-Röntgenaufnähme (31) bestimmt wird.
摘要:
A method of and apparatus for processing optical coherence tomography (OCT) scans through a subject's skin (7), the method comprising: receiving at least one OCT scan through the subject's skin (7), each scan representing an OCT signal in a slice through the subject's skin; processing each OCT scan so as to determine the presence of at least one blood vessel (9) in each scan; determining a diameter of at least one of the at least one blood vessels (9) whose presence has been determined; and typically determining a depth profile of blood vessel density for different vessel diameters.

A skin inspection tool is described. The skin inspection tool utilizes a captured skin area image to identify and classify skin lesions, and displays the image with identified skin lesions on a user interface device, such as a tablet, mobile device, or computer and computer screen. The skin area image display is modifiable by user input. An improved skin lesion inspection method is also described. The systematic inspection method is described for optimizing assessment of inflammatory and non-inflammatory skin lesions. This general method takes into account a skin inspection tool and user input to optimize assessment of skin lesions.

In part, the disclosure relates to intravascular data collections and generation of representations thereof include one or more view of regions associated with side branches or arteries such as a carina or bifurcation. In one embodiment, accessing a set of intravascular data stored in machine readable memory; performing side branch detection with regard to the intravascular data to identify one or more side branches; and identifying a plurality of frames for the one or more side branches is performed. An automatic viewing angle that is toggleable via a user interface is used in one embodiment.

An optical measurement system method for measuring a characteristic of a subject's eye use a probe beam having an infrared wavelength in the infrared spectrum to measure a refraction of the subject's eye at the infrared wavelength; capture at least two different Purkinje images at two different corresponding wavelengths from at least one surface of the lens of the subject's eye; determine from the at least two different Purkinje images a value for at least one parameter of the subject's eye; use the value of the at least one parameter to determine a customized chromatic adjustment factor for the subject's eye; and correct the measured refraction of the subject's eye at the infrared wavelength with the customized chromatic adjustment factor to determine a refraction of the subject's eye at a visible wavelength in the visible spectrum.
摘要:
A medical data processing method, performed by a computer, for measuring the spatial location of a point on the surface of the body of a patient, comprising the steps of: - acquiring at least two two-dimensional image datasets, wherein each two-dimensional image dataset represents a two-dimensional image of at least a part of the surface which comprises the point, and wherein the two-dimensional images are taken from different and known viewing directions; - determining the pixels in the two-dimensional image datasets which show said point on the surface of the body; and - calculating the spatial location of the point from the locations of the determined pixels in the two-dimensional image datasets and the viewing directions of the two- dimensional images; wherein the two-dimensional images are thermographic images.
