Description

Technical Field

[0001] The present invention relates to the field of medical devices, and in particular to an integrated imaging device and method. Background Art

[0002] Positron emission tomography (PET) and single photon emission computed tomography (SPECT) are both medical imaging techniques used to diagnose and study a variety of diseases.

[0003] PET uses positron emission tomography technology. When radioactive isotopes decay, positrons are emitted. These positrons annihilate when they encounter negative electrons in the tissue, producing two gamma photons with an energy of 511keV flying in opposite directions. The PET scanning ring locates the position of the radioactive isotope by detecting these two gamma photons and generates images through computer reconstruction algorithms.

[0004] SPECT uses single photon emission tomography, which directly emits single gamma photons when a radioactive isotope decays. The SPECT scanning ring detects these photons through a rotating gamma camera and generates images through a computer reconstruction algorithm.

[0005] In clinical practice, both PET and SPECT are based on the principle of radionuclide tracer detection and are deployed in nuclear medicine departments as clinical disease diagnostic imaging equipment. The high cost of testing leads to a low frequency of use of both. In addition, both are generally packaged in two fixed examination rooms, each occupying a large space.

DETAILED DESCRIPTION

[0025] In order to make the above-mentioned purposes, features and advantages of the present application more understandable, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present application.

When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. "Substantially equal" or "substantially equal" as used herein means that the difference between the two is within an error range that is considered equivalent in the art. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein are only for the purpose of describing specific embodiments and are not intended to limit this application. The terms "and / or" or "and / or" used herein include any and all combinations of one or more of the related listed items.

[0028] In response to the technical problems existing in the prior art, the present application proposes an integrated imaging device, which integrates PET and SPECT into one device, thereby improving the utilization rate of the overall equipment and reducing the space occupied. Both PET and SPECT detection can be achieved in only one examination room, and the cost is well optimized.

[0029] Some preferred embodiments of the present application are described below with reference to the accompanying drawings. It should be noted that the following description is for illustrative purposes and is not intended to limit the scope of protection of the present application.

[0030] In one embodiment, the integrated imaging device may include a PET detection component and a SPECT detection component, wherein PET stands for positron emission tomography and SPECT stands for single photon emission tomography.

[0031] Specifically, see Figure 1 , Figure 8~Figure 10 , the PET detection assembly 100 includes a plurality of PET detectors 110. Figure 2 , Figure 8~Figure 10 , the SPECT detection assembly 200 includes a plurality of SPECT detectors 210. Figure 3In one example, the PET detector 110 generally includes a scintillation crystal 111 and a photoelectric converter 113. The scintillation crystal 111 is coupled to the photoelectric converter 113. In some cases, a light guide is further provided between the scintillation crystal 111 and the photoelectric converter 113. The scintillation crystal 111 may be an inorganic scintillator, such as a cerium-doped yttrium lutetium silicate crystal (LYSO for short), and the photoelectric converter 113 may be a photomultiplier tube (PMT for short), a photodiode, an avalanche photodiode (APD for short), a silicon photomultiplier tube (SiPM for short), etc. See Figure 4 The SPECT detector 210 includes a collimator 211 and a detection module. The collimator 211 is arranged at the front end of the detection module and can be coupled with the scintillation crystal of the detection module. The detection module is the same as the PET detector 110, that is, the SPECT detector 210 can be formed by the PET detector 110 and the collimator 211. The photons incident on the scintillation crystal are screened by the collimator 211 to ensure that only photons whose incident direction is substantially perpendicular to the light receiving surface of the scintillation crystal pass through. By setting the SPECT detector 210 to be formed by the PET detector 110 and the collimator 211, the system integration can be improved, so that the structures of the SPECT detector 210 and the PET detector 110 are as similar as possible, which is convenient for assembly.

[0032] See also Figure 5 and Figure 6 , Figure 5 The photons enter the scintillation crystal 111 and are deposited therein. The black dots are the deposited points and are output in the form of electrical signals after conversion. Figure 6 and Figure 5 The difference is that the photons are screened by the collimator 211, and only the photons meeting the conditions are allowed to enter the scintillation crystal.

[0033] The number of the PET detectors 110 and the number of the SPECT detectors 210 may be the same or different. For example, see Figure 1 , the number of both is the same, both are 20.

[0034] Specifically, the PET detection assembly 100 and the SPECT detection assembly 200 both have an initial state and a use state. When both are in the initial state, the PET detector 110 and the SPECT detector 210 are arranged according to a preset rule, and at the same detection moment, only one of the PET detection assembly 100 and the SPECT detection assembly 200 is in the use state. It is understandable that at the same detection moment, only one of the PET detection assembly 100 and the SPECT detection assembly 200 is in use.

[0035] More specifically, regarding the preset rule, the PET detector 110 and the SPECT detector 210 may be arranged at intervals, or may be arranged one by one at intervals ( Figure 1 ), or it may be a one-to-many spacing arrangement, for example, one SPECT detector 210 is arranged behind two PET detectors 110, or vice versa. It is understood that the specific form of the spacing arrangement is set according to the number of the PET detectors 110 and the SPECT detectors 210.

[0036] In one example, when both are in the initial state, the PET detector 110 and the SPECT detector 210 are arranged according to a preset rule so that the PET detection component 100 and the SPECT detection component 200 together form a first ring structure ( Figure 1 and Figure 2 ), the first ring structure can be circular or elliptical. It can be understood that the first ring structure does not mean that all detectors are seamlessly connected. There can be some gaps between the detectors. It only requires that the connection lines of all detectors form a ring.

[0037] Specifically, in the use state, the PET detection assembly 100 is a second ring structure ( Figure 7 and Figure 8 ), the SPECT detection component 200 is a third ring structure ( Fig. 9 and Fig.10), the diameters of the second ring structure and the third ring structure are both smaller than those of the first ring structure. Similarly, the second ring structure and the third ring structure may be circular or elliptical. It is understandable that the second ring structure and the third ring structure do not mean that all detectors are seamlessly connected. There may be some gaps between the detectors, and it is only required that the connection lines of all detectors form a ring. More specifically, when the PET detection component 100 and the SPECT detection component 200 are both in the initial state and the state is switched, for example, a PET examination is required, all the PET detectors 110 move to form a second ring structure, and all the SPECT detectors 210 are guaranteed to be stationary in the initial state.

[0038] Preferably, in one example, the first ring structure, the second ring structure and the third ring structure are concentric.

[0039] In another example, when both are in the initial state, the PET detector 110 and the SPECT detector 210 are arranged according to a preset rule so that the PET detection component 100 and the SPECT detection component 200 together form a ring structure with an opening. It is understandable that the ring structure with a specific opening should have an obvious opening, and the opening should be an opening that allows the object to be detected to enter the detection field of view of the device during detection. In their respective use states, the PET detection component 100 and the SPECT detection component 200 can also be a ring structure with an opening, and the opening size of the ring structure with an opening can be different from that in the initial state, or it can be transformed into other shapes, such as a ring or an arc.

[0040] In another example, when both are in the initial state, the PET detector 110 and the SPECT detector 210 are arranged according to a preset rule so that the PET detection assembly 100 and the SPECT detection assembly 200 together form a plurality of arc structures. The number of arc structures may be two, three or more, but it should be noted that the maximum number does not exceed the sum of the number of the PET detector 110 and the SPECT detector 210. In their respective use states, the PET detection assembly 100 and the SPECT detection assembly 200 may also be arc structures, and the curvature and number of the arc structures may be different from those in the initial state, or may be transformed into other shapes, such as a ring.

[0041] In another example, when both are in the initial state, the PET detector 110 and the SPECT detector 210 are arranged according to a preset rule so that the PET detection component 100 and the SPECT detection component 200 together form two flat plate structures. The two flat plate structures can be arranged relative to each other or at a specific angle to facilitate the object to be detected to enter the detection field of view. In their respective use states, the PET detection component 100 and the SPECT detection component 200 can also be flat plate structures, and the size of the flat plate structure and the distance between the two can be different from that in the initial state, or can be transformed into other shapes, such as a ring or an arc.

[0042] Applied to any of the above examples, the position of the PET detector 110 changes when the PET detection component 100 switches states, and the position of the SPECT detector 210 changes when the SPECT detection component 200 switches states. For example, in an example where the PET detection component 100 and the SPECT detection component 200 together form a first ring structure when both are in the initial state, when a PET examination is performed, when switching from the initial state to the use state, all the PET detectors 110 gather inwardly, all the SPECT detectors 210 remain stationary, and all the PET detectors 110 form a second ring structure with a smaller diameter than the first ring structure.

[0043] Applied to any of the above examples, the integrated imaging device further includes a first driving mechanism (not shown) and a second driving mechanism (not shown), the first driving mechanism is used to drive the PET detector 110 to achieve the state switching of the PET detection component 100, and the second driving mechanism is used to drive the SPECT detector 210 to achieve the state switching of the SPECT detection component 200, and two sets of driving mechanisms are used to drive the PET detector 110 and the SPECT detector 210 respectively to avoid mutual interference. Wherein, the first driving mechanism and the second driving mechanism can both be motors.

[0044] Applied to any of the above examples, the integrated imaging device further includes a sensor (not shown), which is connected to both the first driving mechanism and the second driving mechanism. The sensor is used to coordinate the first driving mechanism and the second driving mechanism, which can further avoid mutual interference between the PET detector 110 and the SPECT detector 210.

[0045] Applied to any of the above examples, the integrated imaging device also includes a fusion system (not shown), which is connected to both the PET detection component 100 and the SPECT detection component 200. The fusion system is used to fuse the data collected by the PET detection component 100 and the SPECT detection component 200, so as to more accurately display the detection results and enable the image to combine the advantages of PET and SPECT at the same time.

[0046] In addition, the integrated imaging device further comprises a detector housing (not shown), and the PET detection assembly 100 and the SPECT detection assembly 200 are arranged in the detector housing. In some cases, the integrated imaging device further comprises an examination bed (not shown).

[0047] The integrated device provided in the present application can realize multi-functional imaging in one machine by integrating the PET detection component and the SPECT detection component into an all-in-one machine, and can also reduce the equipment configuration cost and save equipment installation space. While innovating in technology, it clearly reduces the cost of clinical application in site space, equipment purchase, operators and operation management, etc., to achieve optimal operation.

[0048] Corresponding to the above-mentioned integrated device, the embodiment of the present application also provides an integrated imaging method. Fig.11 FIG. 1 is a flow chart of an integrated imaging method in one embodiment of the present application. Fig.11 As shown, the integrated imaging method provided by the present application generally includes: S10: receiving a scanning instruction, wherein the scanning instruction includes a PET scan or a SPECT scan; S20: Acquire the current status of the PET detection component and the SPECT detection component; S30: judging whether it is necessary to adjust the state of the PET detection component or the SPECT detection component according to the scanning instruction and the current state; S40: If not, start the PET detection component or the SPECT detection component to perform scanning; S50: If yes, adjust the state of the PET detection component or the SPECT detection component, and after the adjustment is completed, start the PET detection component or the SPECT detection component to scan.

[0049] It is understandable that when the scanning instruction is a PET scan, it is checked whether the current state of the PET detection component is in use and whether the current state of the SPECT detection component is in the initial state. If both are true, the PET detection component is started for scanning. If the PET detection component is not in use or the SPECT detection component is not in the initial state, the PET detection component is adjusted to the use state and the SPECT detection component is adjusted to the initial state, and then the PET detection component is started for scanning. When the scanning instruction is a SPECT scan, it can be deduced by analogy based on the above-mentioned PET scanning process.

[0050] In addition, in a further example, the scanning instruction further includes fusion scanning, and the integrated imaging method further includes: S60: determining a scanning order according to the current states of the PET detection component and the SPECT detection component; S70: switching the states of the PET detection component and the SPECT detection component and performing scanning in sequence according to the scanning sequence.

[0051] It is understandable that when the current state of one of the PET detection component and the SPECT detection component is the initial state and the current state of the other is the use state, the detection component in the use state is directly used for scanning first, and the state is switched after scanning to simplify the process. When both the detection component and the SPECT detection component are in the initial state, the PET scan can be performed first and then the SPECT scan can be performed according to the system setting. The order can be adjusted here. Of course, it is understandable that the PET detection component needs to be adjusted to the use state before scanning, and the state is switched after one scan is completed, and then another scan is performed.

[0052] After step S50 and step S70, the integrated imaging method further includes performing PET imaging, SPECT imaging or fusion imaging according to the scanning instruction.
