Objective: to develop a landmark suitable for fast image acquisition of the sacroiliac ligament in the longitudinal section. Material and methods. The position of the longitudinal axis of the sacro-ligamentous ligaments relative to the line of the spinous processes on the sonograms of 36 patients (the age range was 27-80) and 33 cadavers (the age range was 50-75) has been determined. Results. The obtained data allow to trace the image of the sacrotuberous ligament in the longitudinal section quickly (using the ischial tuberosity as a landmark and orienting the scanning plane of the sensor at an angle of 19-25° according to the line of the spinous processes).
Amount of data in collecting data of fabric image in the textile industry put forward a new challenge to sensor end. Compressed Sensing (CS) breaks limit of conventional Shannon’s sampling theorem, so we can reconstruct a signal in Sub-sampling rate. In addition, theoretical analysis tells us that collecting the fabric image data by CS method have a better advantage than collecting the general image data. Having reconstructed three fabric images and one general image by CS method, we can easily find that the former have a high quality of reconstruction.
