The application relates to the technical field of textile printing and dyeing, and discloses a waterless printing and dyeing process intelligent control method and system.The method comprises the following steps: collecting dye dispersion and fabric fiber density data in a waterless medium, and generating an initial concentration distribution map; inputting a convolutional neural network to identify concentration instability regions and local deviation values; if the deviation exceeds a preset threshold, iteratively optimizing dye injection parameters to obtain an optimized concentration distribution map; segmenting the regions and extracting dye penetration path vectors of high fiber density regions; determining regional adsorption adjustment coefficients through a support vector machine; updating the parameters to obtain a dynamic concentration regulation sequence; iteratively optimizing the final uniform coloring distribution through coloring simulation; and extracting quality indicators to optimize process parameters and determine a production compatibility scheme.The application solves the problem of uneven dye dispersion through multi-dimensional data fusion and intelligent algorithm regulation, and improves coloring uniformity, process stability and production compatibility.

The invention discloses a mammary gland calcification focus dye positioning method and a dye positioning needle, and relates to the technical field of medical instruments.The dye positioning needle is used for being installed on a three-dimensional positioning arm of a molybdenum target host and comprises a needle cylinder, dye is contained in the needle cylinder, one end of the needle cylinder is provided with a liquid outlet end, and a piston is further arranged in the needle cylinder in a sliding mode; the piston is configured to drive the dye to be discharged from the liquid outlet end during sliding; the needle head comprises a base part and a needle tube, the base part is detachably mounted at the liquid outlet end of the needle cylinder, and the needle tube is used for guiding the dye discharged from the liquid outlet end to be injected into the breast so as to mark and position boundary dyeing of a breast focus. The dye positioning needle injects dye into the four boundaries of the innermost side, the outermost side, the uppermost end and the lowermost end of the mammary gland calcification focus under the guidance of the molybdenum target machine positioning system, and dye marking positioning is achieved. And meanwhile, dye mark positioning of the four boundaries is combined with center point positioning of the metal guide wire, so that crossed three-dimensional boundary positioning can be realized.
