Systems and methods for tuning ultrasound imaging are provided herein. The method comprises: displaying a first scan-converted ultrasound image on a display (S411) based on a first scan line of ultrasound imaging data; receiving screen coordinates of a display point in the first scan converted ultrasound image, the display point having a corresponding depth (S412); converting the screen coordinate of the display point into a data coordinate of a corresponding data point in the first scan line (S413); adjusting a parameter of the first scan line at a scan depth of the data coordinates of the data point to provide a second scan line of the ultrasound imaging data, including the adjusted parameter (S414); performing a scan conversion on the second scan line to obtain a second scan converted ultrasound image, where the second scan converted ultrasound image is changed at a depth of the display point in response to the adjusted parameter (S415); and displaying the ultrasound image converted by the second scan (S416).

Disclosed herein is an optical system that combines optics with a one-dimensional scanner to achieve two-dimensional scanning. The system includes a light source emitting a beam, which is steered in one dimension by a scanner. The optics then convert this one-dimensional scan into a two-dimensional scan across the target scene. The optics comprises multiple distinct optical channels integrated into a single surface, each designed to manipulate light in a specific manner. This arrangement allows for precise control over beam direction, size, and shape, enabling selective illumination of scene elements and adaptable scanning patterns. The system also incorporates a detector and control circuitry to generate a depth map of the scene.

The application discloses a curve weld processing method based on a pre-scanning mode, comprising the following steps: scanning and converting to obtain weld point cloud data in a workpiece coordinate system; performing filtering processing on the obtained point cloud data to obtain filtered data; according to the angle value of the point data in the workpiece coordinate system, the filtered data is segmented according to the angle, and there is overlap between every two segments, curve fitting is performed on each segment of the segmented data; connecting and merging the curve fitted data; filtering the merged fitted data to obtain a backtracking point; and performing welding setting on the point cloud data after filtering out the backtracking point. In the pre-scanning mode, the obtained point cloud data is preprocessed, segmented, curve fitted, merged and filtered to the backtracking point, so that one-time welding of an irregular spiral weld in the pre-scanning mode can be realized, welding cost is reduced, and the method can be suitable for regular or irregular curve welds, welds with large local curvatures, special welds such as wrap angles or weld segments, and the like, and the weld data is accurate.

A method (400) includes receiving an image scan (40) of a patient and extracting, from the image scan having a first image format (40A), metadata (202). The method also includes standardizing the metadata extracted from the image scan having the first image format according to a format of a schema (200) associated with a relational database (190), and storing the received image scan having the first image format in data storage (180) and the standardized metadata in the relational database. The method also includes converting the image scan having the first image format into a corresponding image scan having a second image format (40B) different than the first image format, and storing the corresponding image scan having the second image format in the data storage.
