Referring to fig. 1, in one embodiment, a radiation detection system 100 includes a gamma ray detector 120 and a position and orientation adjustment mechanism 110. The gamma ray detector 120 is used to detect molecular imaging information of the lesion area of the patient 200. The gamma-ray detector 120 is installed at the end of the position and posture adjusting mechanism 110, and can drive the gamma-ray detector 120 to move, so as to detect the radioactivity of the lesion region of the patient 200.

The gamma ray detector 120 is used for performing radioactive detection on the patient 200, and can detect a lesion region of a living body and generate a molecular image containing biological physiological information, thereby providing assistance for diagnosis and treatment of medical staff. Specifically, a radioactive isotope medicament is injected into a specific organ in the body of the patient 200, the isotope medicament is enriched in a region of a human body where metabolism is vigorous, such as a tumor or inflammation region, the region is a focus region, the isotope decays and releases gamma rays, the intensity of the gamma rays released by the patient 200 can be detected when the gamma ray detector 120 moves along the body surface of the patient 200, and a region with high ray intensity, such as the tumor or inflammation region, is determined, and the region is the focus region. Moreover, after receiving the radiation intensity of the focal region, the gamma ray detector 120 reconstructs the image of the detected point carrying the spatial position information detected in each direction through the reconstruction algorithm of the computer, so as to obtain the spatial distribution of the gamma rays in the living body, thereby generating a molecular image with the gamma ray information, and further tracking and monitoring the focal region of the patient 200 in real time.

Also, the gamma ray detector 120 is provided at the end of the position and orientation adjusting mechanism 110. The position and orientation adjusting mechanism 110 has a two or more degrees of freedom of motion capability. On one hand, the position and orientation adjusting mechanism 110 has a larger movement range, so that when the position and orientation adjusting mechanism 110 drives the gamma-ray detector 120 to move, the gamma-ray detector 120 can have a larger movement space, so that the gamma-ray detector 120 can perform comprehensive detection on the body of the patient 200 to determine the region with high radiation intensity. On the other hand, the position and posture adjusting mechanism 110 may also adjust the position and/or posture of the end thereof, and further adjust the position and posture of the gamma ray detector 120, so that the gamma ray detector 120 may be aligned to the lesion area of the patient 200 at any angle and at any distance, so as to obtain a molecular image of the lesion area with higher quality.

Because the existing detector is arranged in the imaging body, the detector is driven to rotate by the rotary motion frame of the imaging body, and the radioactivity detection of a patient is realized. However, the rotating motion frame in this way has only a single degree of freedom, so that the detector can only detect the image of the lesion area of the patient at a single angle, which affects the imaging quality of the image. Therefore, the utility model discloses a radiation detection system 100 sets up gamma-ray detector 120 independent of formation of image organism 400 to adopt position and posture adjustment mechanism 110 to drive gamma-ray detector 120 and realize the kinematic position of six degrees of freedom in space, when making gamma-ray detector 120 carry out the radioactivity detection to patient 200 again, can carry out the molecule image information formation of image to the focus region with arbitrary angle and/or position, improve the formation of image quality of image, the medical personnel's of being convenient for diagnosis.

Moreover, when the position and posture adjusting mechanism 110 acquires the molecular image information, the gamma ray detector 120 can be driven to move to any angle above the lesion area, and the distance between the gamma ray detector 120 and the lesion area can be adjusted, so that the problem of poor imaging quality caused by acquiring the metabolic information of the lesion area from a fixed direction at present is effectively solved, the molecular image information of the lesion area in any direction is acquired, the image quality of the molecular image information is improved, and the diagnosis of medical care personnel is facilitated.

The radiation detection system of claim 1, wherein the position and orientation adjustment mechanism comprises a mounting base and a robotic arm assembly disposed on the mounting base, the gamma ray detector being mounted at a distal end of the robotic arm assembly, and the robotic arm assembly comprises a serial robotic arm and/or a parallel robotic arm.

3. The radiation detection system of claim 2, wherein said robotic arm assembly comprises a plurality of rods and a plurality of joint shafts, said plurality of rods being rotatably connected in series by said joint shafts, a head end of said plurality of rods being rotatably mounted to said mounting base by said joint shafts, and a tail end of said plurality of rods being rotatably mounted to said gamma ray detector by said joint shafts.

4. The radiation detection system of claim 2 or 3, wherein the mounting base is detachably disposed on an end face of the imaging body;

or the mounting seat is detachably arranged on the hospital bed.

5. The radiation detection system of claim 2, wherein the mounting block is provided with an axially extending bore having a transmission line disposed therein.

6. The radiation detection system of claim 5, wherein the transmission line extends beyond the mounting block and is disposed along an outer contour of the robot arm assembly.

7. The radiation detection system of claim 2, wherein an end of the imaging body has a top beam disposed above the scanning bore of the imaging body, and wherein the mounting block is disposed on the top beam of the imaging body.

8. The radiation detection system of claim 2 or 3, further comprising a sliding track disposed on a floor, wall, or ceiling;

9. The radiation detection system of claim 2 or 3, wherein the position and orientation adjustment assembly further comprises a mounting plate disposed at an end of the robotic arm assembly, the mounting plate removably mounting the gamma ray detector.

10. A medical apparatus comprising an imaging body, a patient bed, and the radiation detection system of any one of claims 1-9, the imaging body having a scanning bore into which the patient bed moves;
