Method and device for segmentation of breast cancer pathologic image

ActiveCN108364288AImage enhancementImage analysisBoundary refinementPathologic
The present invention discloses a method for segmentation of a breast cancer pathologic image. There are three main modules consisting of data preprocessing, cell nucleus detection and cell nucleus boundary refinement segmentation. Pathology experts perform artificial calibration of a cell nucleus boundary, the pathologic image is subjected to standardization processing to eliminate dying difference, a training sample based on a cell nucleus pixel, and a cell nucleus boundary pixel and a background pixel is made to train a convolutional neural network classifier and achieve a classifier basedon a Patch image center pixel. A trained convolutional neural network model is detected on the whole pathologic image to output a probability graph, a postprocessing algorithm is employed to generatea binary image as an initialized shape outline of an active outline model, and the active outline model is employed to perform refinement segmentation of the cell nucleus boundary. The method and thedevice for segmentation of the breast cancer pathologic image are high in segmentation accuracy, and can achieve the algorithm for segmentation of overlapped cells in the breast cancer pathologic image.

Optical methods and systems for rapid screening of the cervix

A method and a system is provided for discriminating between healthy cervical tissue and pathologic cervical tissue based on the fluorescence response of the tissue to laser excitation (LIF) and the backscatter response to illumination by white light (in the spectral range of 360 to 750 nm). Combining LIF and white light responses, as well as evaluating a spatial correlation between proximate cervical tissue sites in conjunction with a statistically significant “distance” algorithm, such as the Mahalanobis distance between data sets, can improve the discrimination between normal and abnormal tissue. The results may be displayed in the form of a map of the cervix representing the suspected pathology.

System and method for providing information for detected pathological findings

A system and method of providing information concerning pathological findings evidenced by radiographical reports. A medical care provider may request a radiographical image, in particular, an MRI image of a region of the body. The region of the patient's body is scanned and the images are read and interpreted to determine if there is a positive finding of a pathology. If a pathology is detected, the generated scanned images are reviewed for a radiographical image that best depicts the detected pathology and the image is selected for further annotation. The image is then annotated to highlight and more fully describe and delineate the pathology thus alerting the medical care provider of the pathology's existence. In addition, the report may be further delineated with an identifying mark informing the referring physician of a positive finding of a pathology.

System and method for synthesizing leads of an electrocardiogram

A method for synthesizing electrocardiogram leads includes obtaining a sequence of voltage-time measurements for a set of electrocardiogram leads and subjecting the measurements to abstract factor analysis to obtain a set of eigenvalues and associated eigenvectors. A minimal subset of electrocardiogram leads is identified from which the voltage-time measurements can be calculated with acceptable error. Simplex optimization is performed on a subset of the voltage-time measurements measured with the minimal subset of electrocardiogram leads to obtain a universal transformation matrix, and the universal transformation matrix is multiplied by the subset of the voltage-time measurements to calculate the full set of voltage-time measurements. The full set of leads can be used to calculate a body surface map, and the eigenvalues can be tracked in time to predict the onset of pathology such as myocardial infarction.

Methods and compositions for the treatment of malignant melanoma, breast, prostate, colon, papillary thyroid and pancreatic cancer

It is now recognized that chronic inflammation is an important risk factor for the development of cancer. The proinflammatory cytokine IL-6 is implicated in cancer because it is important for the activation of STAT, a key regulator of cancer growth, survival, metastasis, immune evasion and angiogenesis. Increased IL-6 and Stat-3 exists in vitro in pancreatic cancer, malignant melanoma, papillary thyroid cancer, breast cancer, colon cancer, and prostate cancer cells with high basal expression of Toll-like receptor 3 (TLR3) and Wnt5a. IL6 / STAT3 activation, mediated by overexpressed TLR3 signaling, appears important in the tumor growth process, it may increase Wnt5a signaling, and be associated with increased cellular growth and migration. Using a novel inhibitor of pathologic TLR3 signaling (5-phenylmethimazole [C10]) we have demonstrated decreases in these markers plus suppression of cell growth and migration in human pancreatic cancer, malignant melanoma, papillary thyroid cancer, breast cancer, colon cancer, and prostate cancer cells.
