Problems solved by technology

However, there are still many deficiencies in G-SCAN scanning. Due to the low field strength of the open MRI scanner in the upright position, the image quality is poor compared with high-field MRI, and the scanning time is long. Difficult to maintain posture; upright lumbar spine MRI studies are limited to morphological findings

Embodiment 1

[0033] Three-dimensional scanning imaging of patients in standing position:

[0034] Such as figure 1 and figure 2As shown, after the operator enters the basic information of the patient, he selects the vertical three-dimensional scanning mode. After the confirmation of the auxiliary system, the patient stands correctly on the standing platform 3. The auxiliary system defines the required scanning inspection range, starts the inspection, and the equipment presses Control the operation of the required logical action: the rotating scanning table 10 rotates, the ball tube 6 emits the beam as required, the dynamic flat panel detector 7 receives the projection information, the control system transmits and saves the data, and after scanning for one week, the scanning frame 5 moves down by one imaging height Carry out the next scan until the defined truncation is scanned, and the machine returns to the initial state. The patient leaves the machine. The data processing system gene...

Embodiment 2

[0036] Three-dimensional scanning imaging of the patient in the supine position:

[0037] like image 3 , Figure 4 and Figure 5 As shown, after the operator enters the basic information of the patient, the operator selects the horizontal three-dimensional scanning mode, and the system will switch to the horizontal scanning mode: the scanning frame 5 is turned 90 degrees at the height H Figure 4 state, the scanning couch 12 is lowered to the lowest final initial position.

[0038] Under the confirmation of the auxiliary system, the patient lies correctly on the scanning table 12, defines the required scanning inspection range with the auxiliary system, starts the inspection, and the equipment operates according to the logical action required by the control: the scanning table 12 rises to a predetermined height, moves forward Move to the scanning start position, the rotary scanning table 10 rotates, the ball tube 6 emits the beam as required, the dynamic flat panel detecto...

Embodiment 3

[0040] Patient two-dimensional scan imaging:

[0041] In the scanning process of Embodiment 1 and Embodiment 2, the rotating scanning table 10 is only statically photographed in the front and side positions to complete the set axial imaging range of the human body, and DR imaging in standing and lying states can be realized.

[0042] The cone-beam CT multi-directional scanner of the present invention can change the current situation that it is impossible to obtain three-dimensional bone image data in the upright position of the human body. Three-dimensional cone-beam CT imaging and two-dimensional DR shaping can be performed in the standing and lying positions to obtain three-dimensional images of the human skeletal system and soft tissues with high-quality spatial precision and high-quality density precision. Provide good support for clinical biomechanical assessment, diagnosis, treatment, surgical planning, simulation, etc.

Abstract

The invention discloses a cone-beam CT multi-directional scanner, which comprises a host machine frame, a cone-beam CT scanning device, a scanning frame and a rotary drive device; the cone-beam CT scanning device is installed on the frame body of the scanning frame, The scanning frame is connected with the host frame through a rotary driving device, so that the scanning frame can turn over inside the host frame. When flipped to a horizontal state, the human body can be scanned in a standing position; when the flipped to a vertical state, a human body can be scanned in a supine position. The cone-beam CT multi-directional scanner of the present invention can change the current situation that it is impossible to obtain three-dimensional bone image data in the upright position of the human body, and can also change the current situation that the image resolution accuracy of the sagittal plane of the CT image is relatively low. Three-dimensional cone-beam CT imaging and two-dimensional DR shaping can be performed in the standing and lying positions to obtain high-quality three-dimensional images of the human skeletal system and soft tissues with high-quality spatial precision and high-quality density precision.

Description

technical field [0001] The invention relates to the technical field of medical scanning equipment, in particular to a cone-beam CT multi-directional scanner. Background technique [0002] Spinal surgery and pain department are the fastest growing departments in the past ten years. With the development of technology and changes in lifestyle, the number of patients with various pains has exploded, and they are getting younger and younger. Neck, shoulder, waist, and leg pain in the human body, including pain in the hands, arms, and feet, is largely caused by the spine, intervertebral discs, bones, and joints of the human body. With the development of modern clinics, the research and application of bone structure and biomechanics are becoming the key and hot spot in clinical practice. Three-dimensional imaging and 3D printing technology have brought gratifying changes to clinical technology. [0003] As the main means of imaging examination at present: MRI and CT are basically...
