Background

Computer tomography (X-CT or CT) is a device which uses X-ray to carry out tomography on human body, the attenuation information of human body collected by a detector is converted into digital signals after analog-to-digital conversion, an electronic computer calculates the attenuation coefficient of each pixel, and then the image is reconstructed to display the tomography structure of each part of human body.

In various hospitals, when the patients with symptoms are subjected to tomography scanning through CT equipment, medical staff need to know accurate weight data and height data of the patients before scanning, so that the medical staff can calculate and evaluate the dosage of a contrast agent and a scanning scheme, particularly the adjustment and optimization of radiation dose during tomography scanning according to relevant parameters of the corresponding weight data and the corresponding height data. It is well recognized in the industry that the guidelines for the use of CT contrast media also specify that the total amount of contrast media and the injection flow rate are both proportional to the patient's weight, and that optimization of the radiation dose requires consideration of the patient's BMI, and therefore, the patient's height and weight are of great importance. However, the weight data and the height data of the medical staff informed by the patient are often not accurate enough, especially the weight of the patient, the weight of the patient can be changed greatly due to diseases, and a large error exists between the weight data informed by the patient and the actual weight data, so that the dosage of a contrast medium used by the subsequent medical staff and the formulated scanning scheme are not optimal, and the final CT enhanced scanning effect and the scanned CT image cannot reach the optimal state.
