Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention.
The embodiment of the present invention provides a scanning and positioning method, which can be applied to a scanning and positioning system (hereinafter referred to as a system) of PET CT or PET MR, as shown in fig. 1, and includes the following steps:
in step S101, registration information of a scanned object is acquired.
In the present embodiment, when a PET CT or PET MR scan is required, registration can be performed in the system in advance, so that the system can acquire registration information of the scanned object. The registration information may include the name, sex, height, weight, etc. of the scanned object.
Step S102, determining the number of beds needed by the scanning of the scanned object according to the length of the bed, the initial value of the overlapping area between the two beds during scanning and the height of the scanned object.
The length of the bed refers to the length of each PET bed when PET CT or PET MR scanning is performed. The initial value of the overlap between two beds (i.e., the overlap between two adjacent PET beds) may also be referred to as overlapminI.e. the minimum percentage of overlap. In this embodiment, the system extracts the height of the scanned object according to the registration information of the scanned object, so that mathematical calculation can be performed according to the height of the scanned object, the length of the PET bed and the initial value of the overlapping area between the two beds during PET imaging, and the number of beds required during scanning of the scanned object can be further determined.
According to the embodiment of the invention, the height of the scanned object is obtained in advance, so that the bed number required by the scanned object during scanning is calculated and automatically planned, the time for an operation technician to manually adjust the bed number is saved, the examination time is further shortened, and the injury caused by the fact that nuclide drugs stay in the scanned object for too long is reduced.
In one embodiment, the number of beds required for scanning the scanned object is determined according to the length of the bed, the initial value of the overlapping area between the two beds during scanning and the height of the scanned object, and can be calculated by the following method:
let it be assumed that the height of the scanned object, the length of the PET bed, and the initial value overlap of the overlap region between two beds during scanning are knownmin(the unit is percentage), the following expression is required to be satisfied between the bed number couchSize required by the scanned object to scan:
length*couchSize-length*overlapmin(couchSize-1)≥height
since the number of bed bits is an integer, the number of bed bits couchSize required for scanning the object to be scanned can be calculated by the following formula according to the above expression:
wherein the ceil function represents returning the smallest integer greater than or equal to the specified expression.
In one embodiment, as shown in fig. 2, the scan positioning method may further include the following steps:
step S201, determining the actual value of the overlapping area between two beds according to the number of beds needed by the scanned object when scanning and the height of the scanned object.
In this embodiment, after determining the number of beds required for scanning the object to be scanned, in order to avoid the situation that a large part of the first bed or the last bed is not covered by human tissue when the object to be scanned is scanned, the overlap region needs to be adjusted reasonably.
Specifically, in the whole body PET scanning and positioning process, a certain spatial distance is required between the head and the foot of the human body and the boundary region between the first bed and the last bed, and in this embodiment, it is assumed that the spatial distance required between the head of the human body and the boundary region between the first bed and the bed (i.e., the first bed) during the PET scanning is LhThe space distance needed between the sole of the human body and the boundary region of the bed (the last bed) is L during PET scanningfThen, the following relationship needs to be satisfied with the value overlap of the overlap region between the two beds:
couchSize*length-length*overlap*(couchSize-1)＝height+Lh+Lf
from the above relationship, the overlap value between the two beds can be calculated by the following formula:
in this embodiment, ifoverlap≥overlapminDetermining the actual value of the overlapping area between the two beds as overlap; otherwise, determining the actual value of the overlapping area between the two beds as overlapmin。
Step S202, automatically adjusting the overlapping area between the two beds according to the actual value of the overlapping area between the two beds.
In this embodiment, when the actual value of the overlap region between the two beds is determined to be overlap, the overlap region between the two beds is automatically adjusted according to the actual value of the overlap region between the two beds, so as to complete the scanning positioning process. Therefore, an operator does not need to manually adjust the overlapping area between the two beds, automatic planning and adjustment of the overlapping area between the two beds are realized, and the examination time is further shortened.
It should be noted that the scan positioning in this embodiment refers to a process of determining the number of beds required for scanning the scanned object and the actual value of the overlapping area between two beds according to parameters such as the height of the scanned object before scanning the scanned object, and automatically adjusting the overlapping area between two beds so as to perform scanning after the scan positioning.
In one embodiment, the registration information may further include positioning information of the scanned object during scanning, wherein the positioning information may be specific information of lying on the back, lying on the stomach, lying on the side, advanced in head, advanced in feet, or the like of the scanned object during scanning. As shown in fig. 3, the scan positioning method may further include the following steps:
step S301, determining the scanning direction according to the positioning information.
In this embodiment, in order to further improve the scanning efficiency, the scanning direction of the whole-body scout image protocol may be determined according to the positioning information of the scanned object, and then the scanning direction of the scanned object may be determined according to the scanning direction of the whole-body scout image protocol. For example, if the positioning information of the scanned object is head-advanced (i.e. the head corresponds to the center of the magnet), the whole body scout protocol scan is first required during the PET scan. At this time, if the scanning direction of the whole-body scout image protocol is set from foot to head, the bed needs to be moved first when the whole-body scout image protocol is scanned. Therefore, in order to avoid unnecessary bed moving, the scanning direction of the whole body scout image protocol can be set from head to foot, so that the scanning direction of the scanned object is set from foot to head according to the scanning direction of the whole body scout image protocol. During the scanning process of the whole body scout image protocol, the sliding bed board is reset (at the moment, the feet correspond to the center of the magnet). And then can directly carry out the scanning from foot to head to the scanned object after carrying out the scanning of whole body location image agreement to realize also carrying out image scanning at the slide bed board in-process that resets, thereby effectively utilized the time that the slide bed board resets and consumed, promoted scanning efficiency greatly.
Step S302, determining the human body part corresponding to each bed according to the scanning direction, the bed number required by the scanned object during scanning and a preset bed anatomical structure comparison table.
In this embodiment, the table of bed anatomical structure includes the corresponding relationship between the height and the number of beds required for scanning and the length of each part of the human body. As can be seen from the statistical knowledge, the statistical values of the human body-to-leg ratio (i.e., perineal height/height 100) are shown in table 1 below, and the statistical values of the human body-to-head ratio (i.e., height/head full height 100) are shown in table 2 below.
Table 1:
| for male | Woman | |
| Asia | 45.70 | 44.90 |
| Oumei (European and American) | 47.68 | 47.34 |
Table 2:
and the set data table of the corresponding relation between the required bed number and the height range can be established by the formula for calculating the required bed number according to the height. Assuming a PET bed length of 320mm and an initial value of 25% for the overlap between the two beds, the following relationship set data Table 3 can be established according to the above formula.
Table 3:
| number of beds required | Height range (cm) |
| 1 | (0，32] |
| 2 | (32，56] |
| 3 | (56，80] |
| 4 | (80，104] |
| 5 | (104，128] |
| 6 | (128，152] |
| 7 | (152，176] |
| 8 | (176，200] |
| 9 | (200，224] |
In the present embodiment, the correspondence between the height and the number of beds required for scanning and the length of each part of the human body including the head, the trunk, and the lower limbs is known from the above formula and tables 1, 2, and 3. Assuming the Asian male as an example, the following bed anatomy comparison Table 4 can be derived.
Table 4:
for example, if asian male a with a height of 170cm is to be scanned by PETMR whole body scanning imaging, it can be seen from the above table 4 that 7 PET beds are required for scanning the scanned object a, in this embodiment, the overlapping region between the two beds is exemplified by the initial value of 25%, LhAnd LfAll are 3 cm. Assuming the scanning direction is from head to foot, the head length corresponding to the 1 st bed (head length is 23.68cm calculated according to the head length range corresponding to height in Table 4 or Table 2, plus Lh26.68cm) of the patient, and the last three beds correspond to the lower limbs of the human body (the length of the lower limbs is 77.69cm, calculated from the range of lengths of the lower limbs corresponding to the height in table 4 or table 1, plus Lf80.69cm), so the 2 nd bed corresponds to the chest, the 3 rd bed corresponds to the abdomen, and the 4 th bed corresponds to the pelvic cavity. Thereby quickly and intuitively determining the correspondence of each bedThe human body part of (1).
In this embodiment, the overlap between the two beds can be automatically adjusted according to the actual value calculated by the above formula.
Step S303, automatically setting a scanning protocol of each bed according to the human body part corresponding to each bed.
In this embodiment, after the human body part corresponding to each bed is determined according to the method, the scanning protocol required by the human body part corresponding to each bed can be determined according to the protocol table corresponding to each preset anatomical structure of the human body, so that the scanning protocol of each bed is automatically set according to the scanning protocol required by the human body part corresponding to each bed. In this process, the protocols in the protocol table corresponding to each anatomical structure of the human body can be deleted, added or modified according to the needs. The protocol table corresponding to each anatomical structure of the human body comprises scanning protocols corresponding to human body parts determined according to a large number of experiments. The scanning protocol includes various MR protocols and their parameters. Therefore, the automatic setting of the scanning protocol is realized, the workload of an operator is greatly reduced, the damage to the scanned object is reduced while the scanning efficiency is improved, the misoperation or experience influence is avoided, and the scanning precision can be effectively improved.
