Description

Technical Field

[0001] The invention relates to the technical field of medical imaging, in particular to a mobile slide rail CT. Background Art

[0002] CT, or computer tomography, uses precisely collimated X-ray beams, gamma rays, ultrasound, etc., together with extremely sensitive detectors to perform cross-sectional scans one after another around a certain part of the human body. It has the characteristics of fast scanning time and clear images. CT uses X-ray beams to scan a layer of a certain thickness of a certain part of the human body. The detector receives the X-rays that pass through the layer, converts them into visible light, and then converts them into electrical signals by photoelectric conversion, and then converts them into digital signals through an analog / digital converter and inputs them into a computer for processing.

[0003] At present, CT equipment, as a large-scale medical imaging equipment, is usually fixedly installed. Patients need to enter a dedicated CT room to complete the scanning and imaging. In addition, the scanning process mostly adopts the method of moving the patient while the CT scanning equipment does not move. Since some patients, especially critically ill patients, need to move their life support equipment with the patients when they are transported to the CT room for scanning, there are great safety risks for patients and it is very inconvenient. In some special clinical scenarios, such as during surgery, it is necessary to confirm the spatial and anatomical information of the lesion before surgery, to evaluate the surgical effect in time after surgery, or during radiotherapy, when the patient's tumor position and morphology need to be confirmed online, the CT equipment needs to be installed in the operating room or radiotherapy room. Therefore, hospitals are usually equipped with multiple operating rooms or radiotherapy rooms. If a fixed CT is used, the equipment cost of the hospital will increase exponentially. Summary of the invention

[0078] Example 2

[0079] See also Figure 17-Figure 22 , a mobile slide rail CT, wherein the coordinate system of the scanning ring 1 is O1, the coordinate system of the U arm body 2 is O2, and the coordinate system of the base table 3 is O3;

[0080] When in use, since the U-arm body 2 is hinged above the base platform 3, the U-arm body 2 can rotate around the Y-axis of the base coordinate system O3;

[0081] When the slide rail CT is in the moving state, the U-arm body 2 rotates until the YX plane of the U-arm coordinate system O2 is parallel to the YZ plane of the base coordinate system O3, so as to pass through a narrow passage or door frame;

[0082] When the slide rail CT is in the scanning state, the U-arm body 2 rotates until the YZ plane of the U-arm coordinate system O2 is parallel to the YZ plane of the base coordinate system O3, so that the X axis of the U-arm body 2 is parallel to the X axis of the base platform 3;

[0083] And because the scanning ring 1 is hinged on the U-arm body 2, the scanning ring 1 can rotate around the X-axis of the U-arm coordinate system;

[0084] When the CT device is in a moving state, the scanning ring 1 rotates until the scanning ring coordinate system O1 and the U-arm coordinate system O2 completely overlap;

[0085] When the CT device is in scanning state, the scanning plane can be rotated to a specified working angle according to the scanning task;

[0086] Through the above arrangement, the scanning ring 1 and the U-arm body 2 are moved along the Z-axis of the base platform 3, so that the angles of the scanning ring 1 and the U-arm body 2 can be adjusted according to clinical needs.

[0087] Example 3

[0088] See also Fig.10 and Fig. 22 , a mobile slide rail CT, wherein the coordinate system of the scanning ring 1 is O1, the coordinate system of the U arm body 2 is O2, and the coordinate system of the base table 3 is O3;

[0089] When in use, the first U-arm locating pin 2201 is pressed into the U-arm locating pin hole 2208 provided on the slide assembly 34, and the cable handle 204 is pulled up, so that the cable rope 2206 exerts an operating force on the connecting rod 2207 through the guide wheel 2205, and the first U-arm locating pin 2201 is moved in the +Y direction and disengaged from the U-arm locating pin hole 2208, and then the cable handle 204 is released, and the U-arm body is manually pushed to the target position. When the first U-arm locating pin 2201 and the U-arm locating pin hole 2208 are aligned, the first U-arm locating pin 2201 automatically slides into the U-arm locating pin hole 2208 under the action of the first spring 2202 to lock the position of the U-arm body 2;

[0090] When the first U-arm positioning pin 2201 is inserted into the U-arm positioning pin hole 2208c, the YX plane of the U-arm coordinate system O2 coincides with the YZ plane of the base coordinate system O3. In this state, the angle between the U-arm body 2 and the base platform 3 is defined as 0 degrees, and the device is in mobile mode.

[0091] When the first U-arm positioning pin 2201 is inserted into the U-arm positioning pin hole 2208a, the Z axis of the U-arm coordinate system O2 is parallel and in the same direction as the Z axis of the base coordinate system O3. In this state, the angle between the U-arm body 2 and the base platform 3 is defined as 90 degrees, and the device is in a 90-degree scanning mode;

[0092] When the first U-arm positioning pin 2201 is inserted into the U-arm positioning pin hole 2208b, the Z axis of the U-arm coordinate system O2 is parallel to and opposite to the Z axis of the base coordinate system O3. In this state, the angle between the U-arm body 2 and the base platform 3 is defined as -90 degrees, and the device is in a -90 degree scanning mode;

[0093] Through the above settings, after the slide rail CT enters the treatment room, it can flexibly select a 90 degree or -90 degree scanning mode for scanning according to the indoor conditions, thereby improving the flexibility of the equipment.

[0094] Example 4

[0095] See also Figure 24-26 A mobile slide rail CT, wherein four sets of universal wheels 301 and two sets of running wheel bodies 302 are arranged below the base platform 3, and the four sets of universal wheels 301 are respectively universal wheels 301a, universal wheels 301b, universal wheels 301c and universal wheels 301d, and the two sets of running wheel bodies 302 are respectively running wheel bodies 302a and running wheel bodies 302b;

[0096] When in use, when the walking wheel retracting slide 3409 moves along the length direction of the walking wheel retracting guide rail 3408, the walking wheel gas spring 3407 drives the walking wheel leg 3404 to rotate around the hinge point between it and the slide plate 3417, thereby realizing the retracting and extending movement of the walking wheel body 302;

[0097] When the running wheel retracting slide 3409 moves to the left side, the running wheel body 302 is retracted, and the running wheel retracting slide 3409 moves to the right side, and the running wheel body 302 is lowered.

[0098] When the slide rail CT is in the moving mode, the four sets of universal wheels 301 and the running wheel body 302 are on the ground, and the base shell 3101 is off the ground. The moving direction and speed of the slide rail CT can be controlled by controlling the rotation direction and speed of the two sets of running wheel bodies 302a and the running wheel body 302b;

[0099] When the walking wheel body 302a and the walking wheel body 302b rotate forward at the same speed, the slide rail CT moves forward, and when the walking wheel body 302a and the walking wheel body 302b rotate backward at the same speed, the slide rail CT moves backward;

[0100] When the walking wheel body 302a and the walking wheel body 302b both rotate forward, and the speed of the walking wheel body 302a is less than the speed of the walking wheel body 302b, the slide rail CT moves to the left front;

[0101] When the rotation speed of the walking wheel body 302a is greater than that of the walking wheel body 302b, the slide rail CT moves to the right front; when the walking wheel body 302a and the walking wheel body 302b rotate in opposite directions at the same speed, the slide rail CT rotates clockwise or counterclockwise in place;

[0102] Through the above settings, the CT equipment can be flexibly moved between different work positions, which effectively solves the clinical problem of multiple work positions sharing one CT equipment and is conducive to reducing the hospital's equipment costs.

[0103] Example 5

[0104] See also Figure 11-Figure 14 , a movable slide rail CT, the slide assembly 34 can move along the length direction of the first linear guide rail 3102 on the seat assembly 31, and the gear 3402 of the slide assembly 34 is meshed with the rack 3104 of the seat assembly 31;

[0105] When in use, since the scanning motor body 3403 is mounted on the slide plate 3417, the gear 3402 is mounted on the output shaft of the scanning motor body 3403, and the gear 3402 is meshed with the rack 3104 mounted on the seat assembly 31, the scanning motor driver 3406 is used to control the scanning motor body 3403 to rotate according to the scanning parameters, thereby driving the slide assembly 34 and the U-arm body 2 and the scanning ring 1 mounted on the slide assembly 34 to move according to the scanning parameters, thereby realizing a scanning method in which the scanning ring moves while the patient does not move;

[0106] The above settings effectively solve the potential risks and inconveniences caused by moving life support equipment when scanning critically ill patients. In addition, due to the use of a scanning method in which the patient does not move but the scanning moves, the problem of motion artifacts caused by the movement of the patient is solved, thereby improving the imaging quality.

[0108] See also Figure 1-Figure 27 A mobile slide rail CT, wherein the rotor controller 1105 is the control center of the rotor assembly 11, and controls the battery module 1107, the data acquisition module 1106, the rotor drive assembly 13, the high voltage generator 1103 and the collimator 1108. The U arm controller 2102 is the control center of the U arm body 2 and the base platform 3, and controls all devices of the U arm body 2 and the base platform 3. The rotor controller 1105 and the U arm controller 2102 communicate data via the slip ring 1203.

[0109] When in use, the grid power enters the charger 2105 through the interface 3103, and then charges the battery module 1107 through the slip ring 1203, so that the battery module 1107 can provide power for the power load on the rotor assembly 11. The battery module 1107 can also transmit the power to the power module 2106 installed on the U-arm body 2 through the slip ring 1203, and then the power module 2106 provides power for the various power loads of the U-arm body 2 and the base platform 3.

[0110] The raw data collected by the data acquisition module 1106 on the rotor assembly 11 is transmitted to the rotor computer 1104 also installed on the rotor assembly 11. The raw data is reconstructed into CT image data by the rotor computer 1104, and then sent to the wireless router 2103 installed on the U-arm body 2 via the wireless network, and then transmitted to the U-arm controller 2102 via the wireless router 2103 and finally displayed on the user interface of the control box 201. It can also be connected to a remote control device through the interface 3103, thereby directly communicating with the U-arm controller 2102 through the interface 3103, controlling the slide rail CT and acquiring CT image data.

[0111] Through the above settings, the CT equipment is installed on a movable base. At the same time, the battery module 1107 of the CT equipment allows the equipment to rely on its own energy storage to work, and gets rid of the constraints of cables on the equipment. In addition, since the CT equipment can rely on its own energy storage to work, the reliability requirements for the hospital's power grid facilities are greatly reduced, and normal operation can be achieved in the event of an unexpected power outage. It is particularly suitable for rescue scanning of critically ill patients and use in field and disaster relief scenarios, expanding the scope of application.
