Description

Medical image PACS system and examination association management method thereof

Technical Field

The present invention belongs to the field of Picture Archiving and Communication Systems (PACS), and relates to a medical image PACS system having a history examination management function.

Background

PACS is a system that is commonly used in hospitals to store, manage, and view a large number of medical images generated in the hospitals. With the rapid development of hospital informatization in recent years, more and more devices use digital storage, and the number of images stored by a PACS system in a hospital is also rapidly increasing. The same patient may undergo multiple different types or the same type of imaging examinations at different times, resulting in a large amount of historical data. When a doctor views an examination image of a patient through a PACS in daily work, other relevant examination images (such as a historical examination of the patient) are often required to be found from the PACS system for viewing, and finding required image data from a large amount of stored image data is a complicated matter and is easy to make mistakes.

The patient may be examined many times in different hospitals, and when a certain hospital is diagnosed, the historical examination completed in other hospitals is probably needed, so that the urgent need exists for data integration across hospitals.

When a patient is examined in a certain hospital, the patient is usually identified by an identity card or an identity card issued by the hospital, but the identity card may be lost, the identity card number may be changed, so that the patient adopts different identifications for multiple examinations, and a doctor needs to refer to complete historical examination information during diagnosis.

The existing technology is only simple to search according to a plurality of fixed fields such as patient ID, examination description and the like, and images wanted by doctors can not be found in the complex environment of a hospital. And as the hospital scale increases and the informatization degree increases, the historical examination of the patient may have images which are not concerned by many doctors, and the non-selective automatic loading mode wastes the network bandwidth of the hospital greatly.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and examples.

The invention provides a medical image PACS system and an examination association management method thereof, which can flexibly set matching conditions aiming at other association examinations according to a loaded examination when obtaining other association examinations interested by an operator according to the loaded examination, and is beneficial to more quickly, accurately and comprehensively obtaining the other association examinations interested. The related examination herein may include examinations (referred to as historical examinations) performed by the same patient at different times, different image acquisition devices, different departments, different hospitals, etc., or examinations other than the loaded examination (for convenience of description, it is described as a parallel examination, which is not meant to be limited in practice) when the loaded examination is divided into several examination records due to hospital operation habits.

According to the characteristics of the medical image data, the medical image data can be described using four levels as shown in fig. 1: patient, exam, sequence, and image. The mutual relationship is as follows: multiple examinations may be performed before and after the same patient, and at least one sequence of scans may be taken of the patient for a single examination, with at least one image being obtained for each sequence. Based on the above-described relationship, the medical image data of the patient layer is generally stored in the database in units of examination, such as the patient information data 01 stored in the examination 01, and the patient information data 02 stored in the examination 02. Storing in this way allows patient information data from different sources during an examination to be simultaneously maintained in the database. Different patient information data can be used by the same patient in different examinations and still be identified as belonging to the same patient in the present invention because other characteristic matching conditions can be used, so that strict synchronization of patient information is not required between different history periods or different devices. Based on the data structure, when an image included in the examination of a patient is loaded, other relevant examinations of the patient and the image included therein can be searched according to the model of fig. 4, and the images of the examinations are loaded and displayed in a suitable manner. Loaded exams, as described below, refer to one or more images of loaded exams, and what the operator ultimately needs to view is also the image that each exam contains, but because data is stored in units of exams, the exams are used to describe the system and method of the present invention.

When an operator views image data of a certain patient using a medical image PACS system, the operator usually manually loads a certain examination of the patient and observes images included under the examination. In acquiring additional checks associated with loaded checks, the check association management method shown in FIG. 2 may include check acquisition management and check load management, respectively managing how the associated checks are acquired and loaded.

As shown in fig. 3, in the examination acquisition management step, it is determined that the characteristic information that the association examination that the operator wishes to acquire should include is first determined according to the loaded examination, the characteristic information is used as a matching condition for querying the association examination in the system database, and then the corresponding association examination can be obtained by using the matching condition query. The determination method is related to the image data loaded with the examination, and the matching condition used for obtaining the associated examination is adaptively adjusted according to the corresponding content contained in the image data.

For example, patient characteristic information including patient ID, patient name, patient identification number, patient medical insurance number, etc. can be extracted from the loaded examination, and one or more combinations of the patient characteristic information can be used to search for the examination of the same patient in different periods, different places, different acquisition items, etc. The examination here corresponds to the previously described historical examination, and it may be necessary to identify the historical examination of the same patient by a combination of different characteristic information. The association management method of the invention can configure the matching conditions according to the requirements of the operator and identify the previous examination of the same patient.

For example, inspection ID information such as an inspection serial number, an HIS order number, and the like corresponding to the inspection can be extracted from the loaded inspection, and the remaining inspections corresponding to the same serial number and the HIS order number can be acquired using the inspection ID information. The checks here correspond to the parallel checks described previously; this is caused because it is possible for a hospital to split one examination of a patient into a plurality of examinations recorded in the database for practical reasons, and these split examinations share examination ID information. When one of the checks is selected to be loaded, the association management method of the invention can automatically inquire according to the check ID information to obtain other parallel checks.

The matching conditions can be flexibly configured by adopting the above checking acquisition management steps. As shown in FIG. 3, to accurately obtain the associated examination of interest to the operator, the examination acquisition management step may further filter the associated examination, based on the interest and/or purpose of the operator, to remove non-interesting examinations. Specifically, the association management method of the present invention can set the filtering condition, and use the filtering condition and the matching condition in combination to obtain the examination really interested by the operator. The filter condition may be determined based on inspection information of the current load inspection. The filtering condition determined according to the examination information may include an examination type, an examination description, an examination time, an examination place, an examination part, and the like. The examination type includes, for example, ultrasound image, CT, MRI, DR, CR, etc., the examination description includes examination conclusion description, disease description, interpretation conclusion, etc., the examination site may refer to an organ of a patient or a specific section of an organ to which the examination is directed, and the examination site may include a department number, hospital information, etc. The filter condition may also be determined based on operator information reflected by the current loading check. The filtering condition determined according to the operator information may include an operator account and/or operator habits, and the like. For example, for a doctor in the ultrasound imaging department, the account information of the doctor reflects that the department is the ultrasound imaging department, the filtering condition is determined to retain the examination under the ultrasound image, and filter the examination under other acquisition means, because the doctor usually cares about the ultrasound image. Operator habits reflect historical operational information associated with an account, which may reflect both the type of examination that will be viewed, and further reflect the time period during which viewing may be desired under a certain type, etc. The filtering conditions can be automatically extracted according to the current loading inspection, and the logic relation of different filtering conditions is selected and set according to the input of an operator, so that the associated inspection is filtered by using one or more filtering conditions. Of course, the filtering conditions can also be directly entered manually into the system by the operator to perform the filtering based on the loaded exam and his personal information, as described above.

The checking, matching and filtering shown in fig. 3 may be performed simultaneously, that is, the association management method determines the matching condition and the filtering condition first, and uses the matching condition and the filtering condition to query the association check meeting the corresponding condition in the database, thereby completing the checking and obtaining. The examination matching and the examination filtering shown in fig. 3 may also be performed sequentially, that is, the association management method first obtains the association examination corresponding to the loaded examination by querying in the database according to the matching condition, then performs filtering processing on the obtained association examination by using the filtering condition, and filters the non-interesting examination (i.e., the examination that does not meet the requirement of the filtering condition) from the association examination to complete the examination acquisition.

As shown in fig. 4, the checking load management step may include performing a multi-stage load on the obtained associated checks, and configuring a load mode of each stage of associated check respectively. Under the multi-level loading operation, the obtained association check is firstly processed in a grading way according to the grading rule. The association check of each level corresponds to the loading condition of each different level contained in the multi-level loading conditions, and the loading conditions of the different levels can respectively determine different loading contents of the association check to be loaded. The ranking rules may be unified with the matching conditions, i.e., the associated exams may be ranked according to the exam ID information and the patient characteristic information. The examination ID information and the patient characteristic information (and the details thereof) have different priorities in ranking, which may indicate that when two or more examinations meet a certain ranking rule, they are considered to belong to the same level of associated examination even if other ranking rules are not met due to the priority principle. The present invention is not limited to specific ranking rules as long as the association check can be broken down into multiple different levels as the operator intends to accommodate the loading configuration of subsequent different levels. For example, it is preferable to classify checks of the same check ID information into the same-level association check, classify checks in the same check period into the same-level association check, and finally treat the other checks as another-level association check.

In a particular embodiment, the multi-level load conditions may include a high-level load condition, a mid-level load condition, and a default load condition in which the load content decreases in order. The high level loading condition may indicate that all images of the corresponding association check are loaded, the middle level loading condition may indicate that key images of the corresponding association check are loaded, and the default loading condition may indicate that only check information of the corresponding association check is loaded. The key image may be, for example, a lesion marked image. The multi-level loading condition can also be flexibly set according to the requirement, and the above description of the high-level, intermediate-level and default is only a specific example and does not limit the present invention in any way. In other embodiments, as non-limiting examples, the multi-level loading condition may be set such that the loaded content resolution is gradually decreased, the degree of compression of the loaded images is gradually increased, the number of loaded images is gradually decreased, and so on.

In a specific embodiment, a high-level loading condition for loading all images is used as a first-level loading condition, and in the association check of the loaded check, the association check belonging to the parallel check (i.e. the check data recorded by splitting one check into a plurality of checks) corresponds to the first-level loading condition, so that all images of the split checks are loaded. The intermediate level loading condition for loading the key (i.e. partial) image is taken as the second level loading condition, and the associated checks belonging to a certain time period (e.g. the current day or several days) in the associated checks of the loaded check correspond to the second level loading condition, so that the partial images of the associated checks will be loaded. The default loading condition for loading only the checking information is taken as the third level loading condition, and the rest of the associated checks loaded with the checks correspond to the third level loading condition, so that the checking information of the associated checks is loaded. The multi-level loading may be further illustrated by the example described below in connection with FIG. 6.

The checking load management step may include additional substeps. After observing the information of the above-mentioned intermediate level or default level, if the operator considers that it is necessary to further understand the information of other images, an additional command may be triggered to additionally view the image of the related examination. The association management method can receive additional input of an operator, perform association check on loading under the intermediate level loading condition and/or the default loading condition, and perform additional loading on loading content corresponding to at least one upper level loading condition. That is, for the associative checking under the mid-level loading condition, other images that have not been loaded before may be additionally loaded; for the association check under default loading conditions, part of its images or all of its images may be additionally loaded.

The examination loading management step can selectively load different contents for different associated examinations, and can effectively reduce the number of images contained in the loaded examinations and reduce the loads of a medical image PACS system and a hospital network on the premise of not influencing the reading of the PACS by an operator.

The present PACS system can store not only medical image data of a single department or a single hospital, but also data integration between different departments and different hospitals is gradually realized as more and more devices use digital storage. When the PACS system is used for reading, the correlation examination obtained from different PACS system databases can be regarded as the data of the same patient, and the medical image data obtained by crossing the databases needs to be integrated. As shown in fig. 4, the checking and loading management step may include classifying and sorting the obtained association checks from different sources by using a specific rule, and determining the loading configuration when the association check is displayed on the terminal according to the classification result and the sorting result. The subsequent terminal can load the associated examinations by using the loading arrangement, so that the associated examinations of the same patient from different sources (especially different databases) are integrated at one time, and the operator can obtain all the associated examinations desired to be browsed at one time. The classification rules and ordering rules herein may include classification and ordering by patient name, exam type, exam date, and/or acquisition device. For example, when loading, the related examinations belonging to the same patient are determined first, classification is completed, and then sorting is performed according to the examination time of each related examination. The specific classification and sorting method can be flexibly adjusted according to actual requirements.

For example, Zhang Sanqi patient made a CT examination at the first hospital on 1/3 of 2010. In 2013, 11-12 months, Zhang San patients come to the Jia hospital again, and a plurality of ultrasonic examinations are performed. In 5 days 10 months in 2014, Zhang III patient came to the hospital A again, and a CT examination and an MR examination were performed, and a supplementary examination was performed during the MR examination because some problems were not photographed. Then when the doctor opens the MR examination of patient Zhang III in 10/5/2014, the filtering condition is set as 'retrieval radiographic image department image', the grading rule is set as 'first-stage loading corresponds to parallel examination, second-stage loading corresponds to radiographic examination in the current year, third-stage loading corresponds to associated examination before 2014', at the moment, after the associated examination is selected and loaded, the supplementary examination is automatically loaded and displayed because the serial number is the same, the CT examination in the current day is also loaded, but only a few images marked with suspicious lesions by the doctor are displayed, and only the type, time and basic description of the examination are displayed in the CT examination in 1/3/2010. Because the physician configured interest was not to include US, several US exams in 2013 were not displayed, avoiding loading too many useless exams.

FIG. 6 illustrates the results of the implementation of the above example of check association management, and in particular illustrates different load configurations for different levels of association checks under multiple levels of loading conditions. Wherein for the radiologist, in the last obtained associated examination, only the examination images of the radiographic department are presented, and for the secondary associated examination only the key images thereof are displayed, and for the tertiary associated examination only examination information of which type of examination was made on a certain day is displayed. For the sonographer, the last acquired correlation exam included only ultrasound images, as well as only key images for the secondary correlation exam. Fig. 6 shows that for operators with different interests or concerns, even if the data sources are based on the same association check belonging to the same patient, the association check actually interested by the operator is finally obtained by using the association management method of the present invention, without presenting all the association checks to the operator in a general manner, with high accuracy and low system load.

The present invention also provides a medical image PACS system, and fig. 5 illustrates a modular block diagram of the medical image PACS system according to an embodiment. The PACS system comprises communication means 1, storage means 2 and control means 3, the storage means 2 being adapted to store a plurality of medical image data from at least one medical imaging device, the medical image data being stored in the storage means 2 as a plurality of examinations, an examination comprising at least one sequence, the sequence comprising at least one image. The communication device 1 is used to realize incoming communication and outgoing communication of medical image data. The incoming communication stores the image data obtained by the medical imaging equipment in the storage device 2 for later calling and reading. The calling communication provides image data to a display terminal after receiving a reading request. The communication device 1 can also be used for realizing the communication of image data between PACS systems of different hospitals, and corresponds to the data fusion of different courtyards. The control device 3 is used for controlling the storage and communication of medical image data. The control means 3 may be a stand-alone control logic arranged in the PACS system or may be a control module arranged in a computer system communicatively coupled to the PACS system.

The control device 3 of the present invention may further include a check association management unit 31 for managing loading of an association check of the current load check. The check association management unit 31 includes a check acquisition subunit 311 and a check loading subunit 312, where the check acquisition subunit 311 is used to determine the association check to be acquired, and the check loading subunit 312 is used to determine the loading mode of the association check to be loaded.

The check acquisition subunit 311 includes a matching condition determining module 3111 for determining a matching condition for acquiring the association check according to the current load check, and a querying module 3112 for querying in the storage unit using the matching condition to obtain the corresponding association check. The matching condition includes patient characteristic information extracted from the current loading examination or examination ID information, the patient characteristic information can include patient ID, patient name, patient identification number and/or patient medical insurance number, the examination ID information can include examination serial number and/or HIS order number, and the like, and other available examination ID information is determined mainly by actual operation recorded by hospital splitting examination. The inspection acquisition subunit 311 further includes a filtering module 3113, and the filtering module 3113 is configured to: determining a filtering condition according to inspection information or operator information reflected by the current loading inspection; and filtering non-interesting examinations from the associated examinations using a filter condition at the same time as the associated examination is acquired or after the associated examination is acquired. The filtering conditions may include, but are not limited to, inspection type, inspection description, inspection time, inspection execution place, operator account, and/or operator habit.

The check loading subunit 312 is configured to configure a loading mode of the obtained association check when the association check is invoked through the communication unit. In an embodiment, the check loading subunit 312 includes a multi-stage loading module 3121 configured to configure a loading mode of the obtained associated check with a plurality of stages of loading conditions, and the multi-stage loading module 3121 ranks the obtained associated check, where each stage of associated check corresponds to a different stage of loading conditions included in the multi-stage loading conditions, and each stage of loading conditions corresponds to loading contents of the associated check determined to be loaded. The multi-stage loading module 3121 will further determine the loading content to be loaded for each stage of the association check according to the loading conditions of the different stages. For example, the multi-stage loading conditions include a first stage loading condition corresponding to all images included in the loading correlation check, a second stage loading condition corresponding to part of images included in the loading correlation check, and a third stage loading condition corresponding to the check information of the loading correlation check. In this embodiment, the first to third level loading conditions may be defined as high level, middle level, and default loading conditions according to how much of the contents are loaded. The high-level loading condition is a loading condition of the upper level of the middle-level loading condition, the loading condition of the upper two levels of the default loading condition, and the like.

The multi-level loading module 3121 may further include an additional sub-module for additionally loading the loading content of the associated check corresponding to the lower-level loading condition according to the requirement of the operator. After receiving the additional input of the operator, the additional submodule performs associated check on loading under the intermediate-level loading condition and/or the default loading condition and performs additional loading on the loading content corresponding to at least one upper-level loading condition. This additional operation can further improve the operation adaptability at the time of calling the association check.
