Step S401, a DICOM image sending module transmits DICOM images of a patient to an address extraction module and a data storage module through a DICOM protocol; the DICOM image is a DICOM image sequence output by the image equipment or a new DICOM image sequence generated by processing the DICOM image by a post-processing workstation;
Step S402, the address extraction module extracts the IP address of the image equipment or the post-processing workstation corresponding to the DICOM image based on the DICOM image header file information, and sends the IP address to the data storage module;
Step S403, the data storage module extracts and stores patient information, position information of a patient, image checking time, serial numbers of DICOM image sequences, model of image equipment and model of a post-processing workstation based on DICOM image header file information, and receives and stores IP addresses; the method comprises the steps of correspondingly storing patient information, position information of a patient, image examination time, serial numbers of DICOM image sequences, models of image equipment, models of post-processing workstations and IP addresses in a list form, and defining the patient information, the position information of the patient, the image examination time, the serial numbers of the DICOM image sequences, the models of the post-processing workstations and the IP addresses as a first list;
Wherein, the information of the patient comprises name, age, ID, doctor information, medical institution information and the like; the data storage module 30 is part of a PACS database.
In general, the following architecture is adopted in the database of PACS: patient (Patient grade), as the highest ranking; visit (visit level), as a second level; one patient may visit multiple times, with one independent visit record at a time, and only one patient record; study (inspection level) as a third level; multiple imaging examinations may be performed with each patient visit; each time an imaging examination generates a new Study number and gathers under Visit numbers of the present visit, under the Patient's fixed Patient level, and then down to the Serial (image sequence) as the fourth level. If an examination scans multiple sequences, or generates new sequences for post-processing, each sequence will have a unique number placed under the Study. If the imaging device generates multiple sequences of Patient images, then a post-processing workstation processes the images to generate new sequences, all of which are inherited under the same Patient/Visit/Study library table, except for the different numbers of the image sequences. The images of the same sequence are certainly all from one imaging device/post-processing workstation without distinction, but different sequences under the same inspection may indeed be from different devices/post-processing workstations. The PACS server using the management system records the IP address corresponding to the DICOM image sequence into the corresponding position of the Serial list when DICOM communication occurs each time.
FIG. 8 is a schematic diagram showing a first list formed by data storage modules in a method for managing devices based on DICOM transmission addresses according to a fourth embodiment of the present invention; as shown in fig. 8, when the DICOM device of the PACS receives the DICOM image sequence, the model numbers of the imaging device and the post-processing workstation and the IP addresses corresponding to the model numbers are stored in the image sequence table Serial table, including Serial ID, study ID, image examination time (including date and time of generating the DICOM image sequence), serial NO, location information of the patient, model numbers of the imaging device or the post-processing workstation, IP addresses of the imaging device or the post-processing workstation, and so on.
Step S404, the equipment list recording module records the name of each image equipment, the name of each post-processing workstation, the IP address of each image equipment, the IP address of each post-processing workstation and the scheduling data of each image technician; the name of each image device, the name of each post-processing workstation, the IP address of each image device, the IP address of each post-processing workstation and the scheduling data of each image technician are correspondingly stored in a list form and are defined as a second list.
The equipment list recording module belongs to a part of RIS (medical image information management system), when a medical institution configures an own RIS system, corresponding names are set for each image equipment and each post-processing workstation, the names are set according to own requirements, and the IP addresses of the equipment are recorded in the equipment list;
The shift data of the image technician may be in a list form or a chart form, and is not limited in any way.
Step S405, a matching generation module extracts a first list and a second list within a preset time period, and based on the IP address, the model of the image equipment is in one-to-one correspondence with the names of the image equipment, and the model of the post-processing workstation is in one-to-one correspondence with the names of the post-processing workstation, so as to generate a third list for an administrator to check; the parameters of the third list at least comprise the name of the image equipment or the post-processing workstation, the model of the image equipment or the post-processing workstation and the IP address of the image equipment or the post-processing workstation.
Wherein the preset time period is set by the medical institution according to the own requirement, such as a week, a month and the like;
Fig. 9 shows a third column of the intent generated by the matching generation module in the method for managing devices based on DICOM transmission addresses according to the fourth embodiment of the present invention, where, as shown in fig. 9, the device model in the first list is displayed in the third column, the IP address of the device and the corresponding device in the RIS, for example, the DICOM device model with the IP address 172.19.72.101 corresponds to the 16-row CT name of the RIS device, so that it is known that the DICOM image sequence from the IP address 172.19.72.101 is a DICOM image output by the imaging device in the RIS for 16-row CT, which is convenient for the administrator to manage the device.
Wherein the method further comprises: the port extraction module extracts port data of the image device or the post-processing workstation corresponding to the DICOM image based on the DICOM image header file information, and sends the port data to the data storage module.
Wherein the method further comprises: the data storage module also receives and stores port data, and adds the port data into a first list in the form of a list; the device list recording module also records the port data of each imaging device and the port data of each post-processing workstation and adds the port data to the second list in the form of a list.
