Small-sized bedside CT (computed tomography) scanner

Abstract

The invention discloses a small-sized bedside CT (computed tomography) scanner. The small-sized bedside CT scanner comprises a frame, a rotating component, an imaging system and a drag chain component. The imaging system is provided with an X-ray source module and a detector module which are arranged on the same sidewall of the rotating component symmetrically along the axial center, the X-ray source module is connected with the rotating component through a rotating shaft, and the detector module is used for receiving emergent rays from the X-ray source module correspondingly in a translational motion manner. The drag chain component straddles the sidewall of the frame, the straddling length is not more than the semi-perimeter of the frame, one end of the drag chain component is fixed on the frame while the other end thereof is arranged on the sidewall of the frame movably along with the rotating component, and a cable is connected with a power supply and the imaging system through the drag chain component. The small-sized bedside CT scanner mainly solves the technical problem that an existing CT scanner has extremely high requirements on worksite floors.

Description

technical field [0001] The present invention relates to a kind of medical equipment, more specifically, the present invention relates to a small bedside CT scanner. Background technique [0002] In my country, with the continuous growth of national health needs, and the rapid development of central nervous system diseases and critical illnesses, the number of patients who need head CT scans due to brain diseases is increasing every year. Currently, about 20 million brain scans are required each year. However, it is very dangerous or even impossible to send some seriously ill patients to the CT room for scanning examination, because when transferring patients to the CT room, it is often necessary to temporarily stop the use of various important physiological monitoring and some rescue equipment, which has It may aggravate the patient's condition or lead to complications, and it is difficult to provide timely monitoring and treatment measures when the condition changes. Ther...

Problems solved by technology

At the same time, it also has a large ambient dose, which relatively increases the environmental risk of bedside examination

In addition, the scanning aperture of CereTom is only 30cm, the space is small, and it is difficult to be compatible with some important physiological monitoring and rescue equipment

It also uses crawlers to realize scanning movement, which not only has very high requirements on the ground of the workplace, but also the movement of the rack during the scanning process may affect the real-time monitoring of patients

[0005] Bedside CT scanners have the characteristics of light weight, small size, and flexible movement. However, the current medical diagnosis function of bedside CT scanners on the market is relatively simple. They can only perform CT scan detection on patients, and do not have DR filming functions, making patients need to move around Multiple testing rooms are used to complete the required testing information, which brings a lot of inconvenience to patients. Especially for critically ill patients who are not easy to move, a multifunctional CT scanner is needed to facilitate multiple testing. At the same time, the existing A CT scanner needs at least a 360-degree rotation to scan effective data to reconstruct and obtain multiple tomographic images. If carbon brushes and low-voltage slip ring technologies are used for power supply and communication, the cost will be too high and the functions will be wasted. If the end face of the synchronous pulley is configured with a rotary drag chain, the width of the scanning disk will be greatly increased, making the whole machine bloated

Although other overly complex wiring methods can meet the requirements of power supply and communication, there are safety hazards such as scattered, pulled, and twisted cables, and the actual effect is not ideal
