Abstract

The invention discloses an image data transmission method and device. The method comprises the following steps: acquiring a target image data frame; performing compression processing on the target image data frame based on a target processing mode; storing the processed target image data frame in the cache device; and acquiring a to-be-transmitted image data frame from the cache device for data transmission. According to the image data transmission method and device, the acquired target image data frame is compressed, and then the processed target image data frame is stored in the cache device, so that the storage capacity of the cache device can be improved, the number of the image data frames stored in the cache device is increased, the problem of data buffer overflow caused by excessive data retransmission or data transmission link blockage delay due to interference is effectively solved, the robustness of data frame transmission is improved, and a foundation is laid for subsequent accurate and rapid image reconstruction.

Description

technical field [0001] The present application relates to the technical field of tomography, and in particular to an image data transmission method and device. Background technique [0002] A computerized tomography (Computed Tomograph, CT for short) system usually includes a data acquisition unit, a slip ring, a data receiving card, and an image reconstruction unit. During the scanning process of the CT system, in each sampling period, the data acquisition unit will collect and generate an image data frame, and send the image data frame to the data receiving card through the slip ring in real-time serial transmission mode to transmit the data The image reconstruction unit is used for real-time image reconstruction. [0003] However, slip rings are prone to interference, which will cause image data frame transmission errors, resulting in loss of image data frames, and the data receiving card cannot receive image data frames, so it needs to be compensated by post-processing,...
