Description

Technical Field

[0001] The present invention belongs to the field of tomographic imaging equipment, and in particular, relates to a tomographic imaging equipment and an imaging method based on molecular probes. Background Art

[0002] The third generation of computer tomography systems has a gantry with a fixed part and a part that rotates relative to the fixed part. This rotating part has the shape of a drum, on which some components of the computer tomography system are arranged, such as an X-ray source that rotates around a patient arranged in a measurement field during operation of the computer tomography system, an X-ray detector, a control system, etc. The fully equipped drum has a mass of about 800 kg to 900 kg in a system with only an X-ray source and an X-ray detector and rotates at a speed of up to 240 rpm during operation.

[0003] In order to support the drum relative to the fixed part of the machine frame, rolling bearings are currently used in various embodiments. However, these rolling bearings are subject to a certain amount of wear and must be regularly maintained, for example relubricated. In addition, the noise level from the rolling bearings increases with increasing rotational speed, so that it can be perceived as disturbing and requires additional measures to reduce the noise. Summary of the invention

[0004] The purpose of the present invention is to provide a molecular probe-based tomographic imaging device and imaging method. The imaging device is connected by a shaft rod, and the shaft rod is fixed to the frame by a small bearing, which can effectively reduce noise and wear, and the shaft rod can be directly connected to the motor, which is simple to drive. Through the adsorption effect of the suction cup on the surface of the first ring plate, and the clamping and fixing effect of the clamping rod on the peripheral surface of the first ring plate, the entire rotating imaging device can be effectively fixed, the rotation stability is improved, and then the imaging effect is improved.

[0005] The purpose of the present invention can be achieved by the following technical solutions:

[0007] The tomographic imaging device comprises a fixed frame and an imaging device mounted on the fixed frame;

[0008] The fixed frame includes a square frame body, a first through hole for accommodating the imaging device is opened on the square frame body, a C-shaped plate is fixed on one surface of the square frame body, and a second through hole for installing the imaging device is opened at the center of the surface of the C-shaped plate;

[0009] The imaging device comprises a carrier and a rotating clamping device connected to the carrier, the carrier comprises a first ring plate and a second ring plate arranged in parallel, two third ring plates are vertically fixed between the first ring plate and the second ring plate; the rotating clamping device comprises a three-jaw chuck, the three-jaw chuck is fixed on the driving shaft, a circular disc is also fixed on the driving shaft, three seat plates are evenly fixed on the surface of the circular disc along the circumferential direction, a first connecting plate is movably installed on the seat plate, one end of the first connecting plate is rotatably connected to the seat plate, and the other end is connected to the second connecting plate, a first round rod is fixed to the other end of the second connecting plate, a third connecting plate is fixed to both ends of the first round rod, the third connecting plate is installed on the second round rod and the third connecting plate is rotatably connected to the second round rod, the second round rod is fixed to the two side surfaces of the clamping claws of the three-jaw chuck, a clamping rod is fixed to the end surface of the third connecting plate, and a clamping groove for clamping with the first ring plate is provided on the side wall of the clamping rod; a suction cup is fixed to the surface of the clamping claw of the three-jaw chuck, and the suction cup is adsorbed on the surface of the first ring plate; the driving shaft is installed on the C-shaped plate through a bearing, and the driving shaft is connected to the first motor;

[0010] The hospital bed equipment includes a bed base and a bed body matched with the bed base. A limit groove is arranged on the upper surface of the bed base. A side plate is fixed on the upper surface of the bed base, and a threaded shaft is installed through the side plate. Two limit bars are fixed on the lower surface of the bed body, and the limit bars are slidably matched with the limit groove.

[0011] Furthermore, the two end surfaces of the C-shaped plate are fixed to the surface of the square frame and are arranged parallel to the ground.

[0012] Furthermore, a cavity for accommodating the molecular probe imaging system is formed between the first ring plate, the second ring plate and the third ring plate.

[0013] Furthermore, the threaded shaft is rotatably connected to the side plate and the threaded shaft is connected to a second motor.

[0014] Furthermore, a mounting block is fixed to the lower surface of the bed, and the mounting block is threadedly connected to the threaded shaft.

[0015] An imaging method based on a molecular probe tomography device comprises the following steps:

[0016] The first step is to lie on the bed, turn on the second motor, and slowly move the bed along the axial direction of the threaded shaft to transport the patient's head on the bed into the tomographic imaging device, and then turn off the second motor;

[0017] Step 2: After the suction cup is attached to the surface of the first ring plate, the angle between the first connecting plate and the seat plate is adjusted so that the clamping rod is clamped and fixed to the peripheral surface of the first ring plate;

[0022] The present invention includes two ways to fix the entire imaging device. After the suction cup is adsorbed on the surface of the first ring plate, by adjusting the angle between the first connecting plate and the seat plate, the first round rod drives the third connecting plate to rotate around the second round rod through the connecting rod transmission, thereby realizing the rotation of the clamping rod. The rotation of the clamping rod can realize the clamping and fixing of the peripheral side surface of the first ring plate; through the adsorption effect of the suction cup on the surface of the first ring plate, coupled with the clamping and fixing effect of the clamping rod on the peripheral side surface of the first ring plate, the entire rotating imaging device can be effectively fixed, the rotation stability is improved, and the imaging effect is improved.
