An ultrasonic breast tumor morphological quantitative feature extraction method based on a shape histogram

ActiveCN109903278ARich morphological and quantitative feature libraryImprove accuracyImage analysisMISCELLANEOUS TUMORSSonification
The invention discloses an ultrasonic breast tumor morphological quantitative feature extraction method based on a shape histogram. Aiming at defects that in a computer-aided diagnosis system, the traditional ultrasonic breast tumor benign and malignant quantitative feature description is inaccurate. Based on the contour of a breast tumor, a shape histogram of the breast tumor is constructed, andthree morphological quantization characteristics are designed on the basis of the shape histogram, namely the maximum curvature sum, the maximum curvature peak value sum and the maximum curvature standard deviation sum, so as to effectively represent the local benign and malignant difference of the ultrasonic breast tumor; The three morphological quantitative characteristics provided by the invention are applied to the classifier, and the obtained benign and malignant recognition rate of the ultrasonic breast tumor is obviously improved compared with the recognition rate of the traditional morphological quantitative characteristics, so that the practical value is realized. The method can effectively reduce the influence of subjective factors of doctors, is helpful for improving the diagnosis accuracy of the doctors, can be suitable for diagnosis of benign and malignant tumors of other tumors, and has a good application prospect.

Tumor specimen storage device

The invention discloses a tumor specimen storage device which comprises a base plate, a barrel and a supporting rod are arranged on the upper end face of the base plate, a movable cover with a taking-out hole is movably connected to the upper end of the barrel, a lifting device is arranged in the middle, located in the barrel, of the base plate, and a condensing device communicated with the barrel is arranged in the base plate. The cylinder body is composed of a plurality of storage cylinders and installation cylinders, the installation cylinders are movably connected between the adjacent storage cylinders, the supporting rods are provided with fixing rods connected with the outer walls of the storage cylinders and stop devices opposite to the installation cylinders, the inner walls of the installation cylinders are provided with corresponding wall-hanging groove blocks and wall-hanging through groove blocks, and the inner walls of the storage cylinders are provided with communicating grooves. A containing device corresponding to the lifting device is movably connected into the wall-mounted groove block. By arranging a plurality of rotary mounting cylinders, tumor specimens can be placed in multiple layers, the required tumor specimens can be selected in rotation through a single taking-out hole when the tumor specimens are taken out, and then other tumor specimens can be protected.
