The terminology used herein in the description of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
Referring to fig. 1 and fig. 3, the present application provides a data processing method. The data processing method comprises the following steps:
and S10, determining the region of interest.
And S20, screening the data signals corresponding to the region of interest, and transmitting the screened data signals.
It is to be understood that the method for determining the region of interest is not particularly limited as long as the site to be detected of the object to be detected can be marked. In an alternative embodiment, the region of interest may be determined experimentally. In another alternative embodiment, the region of interest may be determined by way of simulation.
By means of the screening it is possible to distinguish between X-ray data included in a region of interest and X-ray data not included in said region of interest. For example, in an alternative embodiment, X-ray data at the edges of the detector 10 are marked as not included in the region of interest based on scan angle information contained in the data signals. In another alternative embodiment, since the attenuation degree of the X-ray data included in the region of interest is different from that of the X-ray data not included in the region of interest, the data signal of the region of interest may be screened and transmitted according to the attenuation degree of the data signal. The screening process described above may be performed in the data processing module 20.
It is understood that the manner of transmitting the data signal of the region of interest to the reconstruction module is not limited in particular, and in an alternative embodiment, the data signal of the region of interest may be transmitted to the reconstruction module 50 by wireless transmission. In another alternative embodiment, a low-cost fiber slip ring or other transmission means may be used to transmit the data signals of the region of interest to the reconstruction module 50.
It will be appreciated that X-rays emitted by the X-ray generator are received as a beam by the detector 10, and the optical signal is converted to an electrical signal, which is then converted to a data signal by analog-to-digital conversion. It CAN be understood that the stator interface module is in communication connection with the data processing module 20 through the CAN, and the stator interface module controls the data processing module 20 through the CAN to control the high-voltage module, so as to control the X-ray generator to pay off. Of course, the above-mentioned method is only one method for controlling the X-ray generator to pay off, and the control of the X-ray generator can be realized by any method known to those skilled in the art.
In this embodiment, the data processing method includes determining an area of interest, screening out a data signal of the area of interest, and transmitting the screened data signal. The data processing method screens the data signals before transmission, distinguishes the X-ray data included in the region of interest and the X-ray data not included in the region of interest, and then greatly reduces the data volume needing to be transmitted by combining the X-ray data not included in the region of interest or only transmitting the X-ray data included in the region of interest, so that the problem of reducing the data volume needing to be transmitted on the basis of ensuring that the required information is not distorted due to compression so as to influence judgment is solved.
In one embodiment, step S10 includes emitting at least two beams at different angles to define the image scanning area. It will be appreciated that each beam defines a scan area and the region of coincidence of the two scan areas may be defined as the image scan area. And then, placing the object to be detected in the image scanning area to finish the positioning of the object to be detected.
In one embodiment, referring to fig. 2, the object to be detected may be scanned by a positioning sheet at two angles, i.e. a positive direction and a lateral direction, to determine the position of the image scanning center, and thus the image scanning area. Then, the part to be scanned of the object to be detected can be placed in the image scanning area, and the positioning of the object to be detected is completed.
It will be appreciated by those skilled in the art that by emitting more than two angularly distinct beams, the image scan area may also be determined.
In this embodiment, the image scanning area of the beam is determined experimentally by emitting at least two beams of different angles by an X-ray generator. And then, the part to be scanned of the object to be detected is placed in the scanning area, so that the part to be detected of the object to be detected is ensured to be positioned in the image scanning area. The X-ray data of the region of interest can then be distinguished from X-ray data not included in said region of interest. Optionally, the data signals not included in the region of interest are combined by means of the data processing module 20. After the data signals are acquired by the detector 10, the data processing module 20 merges the X-ray data, which is located at the edge of the detector 10 and is not included in the region of interest, in each detection range, for example, four pixels are merged into one pixel, and the compression degree may be set according to the needs of the user, for example, 8 pixels are merged into one pixel, or 16 pixels are merged into one pixel, so that the X-ray data, which is not included in the region of interest, at the edge of the detector 10 is compressed to a certain extent, and the amount of data transmitted is greatly reduced compared with the amount of data transmitted uniformly by all the data received in each detection range in the conventional technical solution, where all the data include not only the X-ray data of the region of interest but also the X-ray data not included in the region of interest. The technical scheme greatly reduces the data volume to be transmitted, can ensure that the required information is not distorted, and reduces the problem of the data volume to be transmitted on the basis of good imaging quality.
In one embodiment, step S10 includes:
and acquiring a standard human body model. And adjusting the standard human body model by using the body characteristic information of the object to be detected so as to obtain the human body model of the first object to be detected. And identifying the position of the object to be detected, and adjusting the human body model of the first object to be detected so as to obtain the human body model of the second object to be detected. And marking the region of interest on the human body model of the second object to be detected. Specifically, before scanning, the identity information of the object to be detected is input into the standard human body model, so as to perform personalized adjustment on the standard human body model, and obtain the human body model of the first object to be detected. And recognizing the arrangement position of the object to be detected by using a visual recognition system 80, finishing the registration of the human body model of the first object to be detected and the object to be detected according to the recognition result, and adjusting the human body model of the first object to be detected so as to obtain the human body model of the second object to be detected. Marking the region of interest of the human body model of the second object to be detected, and marking the region on the detector 10 corresponding to the region of interest at each angle.
The standard mannequin may be established in the controller 70. The identity information of the object to be detected can be basic information such as height, sex, age, weight, illness history and the like. The region of interest of the manikin of the second object to be detected is marked in the controller 70. The region of interest may be a heart, a lung, a kidney, etc. When the gantry rotates after the marking is completed, the data of the detector 10 part corresponding to the interested area corresponding to each angle of the bulb is determined in a one-to-one correspondence manner. The received data of the detector 10 can be processed by the data processing module 20, so as to screen out the data of the region of interest, and only the data of the detector 10 corresponding to the region of interest is transmitted. The amount of data transmitted in this way is considerably reduced compared to the conventional solution, in which all data received per detection range are transmitted uniformly, said all data comprising not only X-ray data of the region of interest but also X-ray data not present in the region of interest. The technical scheme greatly reduces the data volume to be transmitted, can ensure that the required information is not distorted, and reduces the problem of the data volume to be transmitted on the basis of good imaging quality.
In one embodiment, the step of obtaining the human body model of the second object to be detected further includes:
and further adjusting the human body model of the second object to be detected by using the pre-scanned image of the object to be detected. Specifically, the object to be detected is pre-scanned, and the pre-scanned image is compared with the identification image of the visual identification system 80, so as to correct the human body model of the second object to be detected.
In one embodiment, the step of identifying the data signal of the screened region of interest further includes compressing, rearranging and/or encapsulating the screened data signal. The steps of compressing, rearranging and encapsulating are basically the same as those of the prior art, and are not described herein again. The amount of compressed, reordered and/or packed data is further reduced.

The X-ray data passing through the region of interest and the X-ray data not included in said region of interest can be distinguished by the screening function of the data processing module 20. For example, in an alternative embodiment, X-ray data at the edges of the detector 10 are marked as not included in the region of interest based on scan angle information contained in the data signals. In another optional embodiment, since the attenuation degree of the X-ray data included in the region of interest is different from that of the X-ray data not included in the region of interest, the data signal corresponding to the region of interest may be screened and transmitted according to the attenuation degree of the data signal.

In one optional embodiment, the data processing module 20 is further configured to combine data signals not included in the region of interest. After the data signals are acquired by the detector 10, the data processing module 20 merges the X-ray data, which is located at the edge of the detector 10 and is not included in the region of interest, in each detection range, for example, four pixels are merged into one pixel, and the compression degree may be set according to the needs of the user, for example, 8 pixels are merged into one pixel, or 16 pixels are merged into one pixel, so that the X-ray data, which is not included in the region of interest, at the edge of the detector 10 is compressed to a certain extent, and the amount of data transmitted is greatly reduced compared with the amount of data transmitted uniformly by all the data received in each detection range in the conventional technical solution, where all the data include not only the X-ray data of the region of interest but also the X-ray data not included in the region of interest. The technical scheme greatly reduces the data volume to be transmitted, can ensure that the required information is not distorted, and reduces the problem of the data volume to be transmitted on the basis of good imaging quality.
In one embodiment, the region of interest determination module is configured to obtain a standard human body model, and adjust the standard human body model, so as to obtain a human body model of the first object to be detected. The interesting region determining module is further used for identifying the arrangement position of the object to be detected and adjusting the human body model of the first object to be detected so as to obtain the human body model of the second object to be detected. The region of interest determining module is further used for marking the region of interest on the human body model of the second object to be detected.
In this embodiment, the region of interest is determined in a simulation manner. At this time, the region of interest determining module may include a controller 70 and a vision recognition system 80. Please refer to fig. 4.
The controller 70 is configured to establish a standard human body model, and perform personalized adjustment on the standard human body model to obtain a human body model of the first object to be detected. The visual recognition system 80 is connected to the controller 70, and is configured to recognize the positioning of the object to be detected, and send a recognition result to the controller 70. The controller 70 completes registration of the human body model of the first object to be detected and the object to be detected through the recognition result, so as to obtain the human body model of the second object to be detected. And marking the region of interest of the human body model of the second object to be detected, and marking the region on the detector 10 corresponding to the region of interest at each angle. And the controller 70 controls the data processing module 20 to screen out the data signal corresponding to the region of interest, and sends the data signal corresponding to the region of interest to the wireless sending module 30. Alternatively, the controller 70 may control the data processing module 20 through a stator interface module.
The standard mannequin may be established in the controller 70. The identity information of the object to be detected can be basic information such as height, sex, age, weight, illness history and the like. The region of interest of the manikin of the object to be detected is marked in the controller 70. The region of interest may be a heart, a lung, a kidney, etc. When the gantry rotates after the marking is completed, the data of the part of the detector 10 corresponding to the region of interest corresponding to each angle of the bulb is determined in a one-to-one correspondence manner. The received detector data can be processed by the data processing module 20 to screen out data of the region of interest, and only the detector data corresponding to the region of interest is transmitted, so that the transmitted data volume is greatly reduced compared with the data volume in the conventional technical scheme in which all the data received in each detection range are uniformly transmitted, and all the data not only include the X-ray data of the region of interest but also include the X-ray data of the region not of interest. The technical scheme greatly reduces the data volume to be transmitted, can ensure that the required information is not distorted, and reduces the problem of the data volume to be transmitted on the basis of good imaging quality.
In one embodiment, the controller 70 includes a registration module 71. The registration module 71 is connected to the visual recognition system 80, and is configured to compare the pre-scan image with the recognition image of the visual recognition system 80, and correct the human body model of the object to be detected. The registration module 71 is arranged to correct the human body model of the object to be detected.
In one embodiment, the data processing module 20 is further configured to compress, rearrange, and/or encapsulate the filtered data signal. The steps of compressing, rearranging and encapsulating are basically the same as those of the prior art, and are not described herein again. The amount of compressed, reordered and/or packed data is further reduced.
