Scanning control system and computed tomography system

Abstract

The invention provides a scanning control system and a computed tomography system using the same. The scanning control system comprises a monitoring module and a preheating control module, the monitoring module is used for monitoring various information probably triggering computed tomography in real time and judging whether an instant scanning mode needs to be started or not, and the preheating control module sectionally control preheating of a ball tube according to instant scanning mode information sent by the monitoring module. By using the scanning control system, when the ball tube is insufficient in heat capacity while a patient urgently needs scanning, the preheating process of the ball tube and other operations can be performed at the same time without causing damage to the ball tube, so that the problem that scanning cannot be performed timely due to the fact that other operations cannot be performed in the preheating process or damage is caused to the ball tube due to the fact that a cold target is used in order to scan the patient as soon as possible in the prior art is solved.

Description

technical field [0001] The invention relates to the field of medical imaging equipment, in particular to a computed tomography imaging system. Background technique [0002] Computed Tomography (CT) system is a layer-by-layer cross-sectional scan of a certain part of the human body with X-ray beams, obtains a certain number of layers of information and then obtains a cross-sectional anatomical map of the human body after computer processing, which is helpful for doctors It can diagnose patients' disease information more accurately and comprehensively, so it has been widely used in the field of modern medical imaging. [0003] From the perspective of the external structure, the CT system mainly includes a frame, an examination bed, and a computer system. The frame also includes a high-voltage generator, a ball tube, a detector and a data acquisition system, and the ball tube is used to produce X-rays. Usually, the tube must be preheated before scanning the patient, otherwise...

AI Technical Summary

Problems solved by technology

Under normal circumstances, the tube must be preheated before scanning the patient, otherwise it will cause greater damage to the tube and greatly reduce the service life of the tube

In the existing CT system, it takes a few minutes to warm up the tube. During these few minutes, doctors generally cannot perform other operations and can only wait.

When the machine is not very busy or does not work continuously, such as at night, and the heat capacity of the tube drops to the threshold, if there is an emergency patient who needs to scan immediately, there are generally three options: the first is to perform normal warm-up, then Patients need to wait for a few more minutes. However, for emergency patients, a few minutes of waiting may cause a great delay in the diagnosis and treatment of the disease; the second is to scan immediately and reduce the scanning conditions, but reducing the scanning conditions will reduce the Image quality, which is very unfavorable for the diagnosis of the disease, may lead to misdiagnosis; third, the doctor chooses to abandon the warm-up stage and directly conduct cold target scanning, which will cause great damage to the tube and greatly shorten the equipment. service life, but this is also what the hospital is not willing to see
