Problems solved by technology
Due to the relatively high image rendering quality required in medical diagnosis, the method of reducing image data transmission by reducing image resolution is obviously not suitable for medical diagnosis
In addition, although there have been some related studies on medical image data transmission in recent years, these studies are all based on two-dimensional image technology, and no mature solutions have been proposed for the stuttering phenomenon of three-dimensional image data during low-bandwidth transmission.

Embodiments of the present invention provide a data transmission method and apparatus, relating to the technical field of communication. A sending time interval of an image operation instruction is adjusted according to a calculated current network bandwidth, so that image data transmission instructions are not accumulated, and the image data is transmitted more fluently. The method comprises the steps that firstly, a client acquires time that the client spends in receiving a designated image and a size of the designated image; and then, the client determines a current bandwidth according to the time that the client spends in receiving the designated image and the size of the designated image, so that the client sends a data transmission operation instruction to an image server according to the sending time interval corresponding to the current bandwidth. The data transmission method and apparatus are suited to three-dimensional image data transmission.
Description
[0001] 【Technical Field】 [0002] The present invention relates to the field of communication technology, in particular to a method and device for data transmission. [0003] 【Background technique】 [0004] With the development of medical technology and the continuous advancement of hierarchical diagnosis and treatment, the demand for data sharing of medical data through communication networks is becoming more and more urgent. However, most medical institutions have uneven network bandwidth. When various medical institutions realize data transmission, especially in the process of 3D image data transmission, data transmission is stuck. [0005] In the current communication technology field, the problem of data transmission jams is solved by reducing the resolution of three-dimensional images. Since the image rendering quality required in medical diagnosis is relatively high, the method of reducing image resolution to reduce the transmission of image data is obviously not suitable for m...
