Description

Medical image archiving and communication system

Technical Field

The invention relates to the technical field of medical information, in particular to a medical image archiving and communication system.

Background

At present, the state is developing a new online medical and health service mode based on the internet, encouraging the construction of medical image, health file, inspection report, electronic medical record and other medical information resource sharing service platforms in the hospital, establishing a medical data sharing and exchanging standard system across hospitals, fully utilizing the internet, big data and other means to obtain the mutual identification inspection and inspection results among medical institutions in the hospital, and improving the prevention and control capacity of major diseases and sudden public health events; encourages to set up independent regional medical inspection mechanism, pathological diagnosis mechanism, medical image inspection mechanism, disinfection supply mechanism and blood purification mechanism, realize regional resources such as medical image center, inspection center, disinfection supply center, logistics service center, etc. share; the system encourages medium and large hospitals to provide services such as remote consultation, remote pathological diagnosis, remote image diagnosis, remote electrocardiogram diagnosis and remote training for basic-level medical health institutions, improves the remote medical service capability, and improves the accessibility of high-quality medical resources and the overall efficiency of medical services.

Nowadays, medical imaging technology has fully entered digital era, and health institutions such as hospitals and the like have a large amount of digital equipment such as computers and the like in the process of diagnosing and treating diseases. With the widespread use of these devices, a great deal of digital medical data is generated, such as fluoroscopy of the patient, video of the detection of internal structures, video of the surgical procedure and associated text descriptions. And uses a PACS (Picture Archiving and Communication System) to centrally store and manage the digitized images generated by various imaging devices. The PACS system and various image devices support and use the DICOM (Digital Imaging and Communication in Medicine) protocol for data sharing and Communication. The DICOM protocol defines not only the communication protocol between the image equipment and the PACS system, but also the format for storing images on mobile archival media (e.g., compact discs, usb disks, etc.). Various imaging devices and PACS systems supporting the DICOM protocol may store images on mobile archival media in a format defined by the DICOM standard.

However, the existing primary medical institution and county-level medical institution areas do not form a regional hospital PACS; although the middle and large hospitals have PACS projects, the traditional PACS generally adopts three architectures: the image data of all medical institutions is centrally stored in an image data center of a district/county health bureau), the image data of all medical institutions is distributed (the image data of all medical institutions is stored respectively, and the data among the medical institutions is retrieved as required when being shared), and the image data of all the medical institutions is combined in a centralized mode and a distributed mode (the image data of all the medical institutions is stored locally, and the recent image data is centrally stored in the data center, so that the retrieval across institutions is facilitated). However, with the rapid development of imaging and the increasing number of cases, the disadvantages of the conventional PACS system gradually appear:

firstly, as time goes on, the amount of imaging data increases in a geometric progression, and hospitals often need to increase the cost of storage equipment and equipment maintenance continuously;

secondly, the development standardization degree of PACS is low, the compatibility between different systems is poor, each hospital adopts different PACS systems, a closed information isolated island is generated, the sharing among different hospitals is difficult to realize, and a set of complete digital imaging data reflecting the disease condition change is difficult to form;

third, in most medical practices, physicians do not need to review the raw data of the imaging examination, and what they are interested in is more imaging diagnosis reports containing example data of images, and hopefully, the multiple imaging reports in the disease process can be seen, and by comparing the imaging images and reports, the judgment on whether the disease is progressing and the treatment is effective is made;

fourthly, mining and analyzing regional medical data is very difficult because the output formats of different types of examination equipment cannot be compatible;

fifth, PACS products are not proprietary in hospitals today, doctors conduct business autonomously, third party diagnostic centers, artificial intelligence diagnoses, user referrals, inquiries, and remote consultations all require cloud PACS product support.

With the development of the industry, the traditional PACS can not meet the requirements of hospitals, and can not realize PACS application, scene application, cross-regional information sharing and the like of more platforms. Therefore, developing a medical image data sharing method, a cloud platform and a system is a trend of future development, and has significant application value and practical significance.

Example one

As shown in fig. 1, a medical image archiving and Communication system according to an embodiment of the present invention includes an inquiry module a101, a user right setting/managing module a102, a dicom (digital Imaging and Communication in medicine) device managing module a103, a system basic information setting module a104, a report single format defining module a105, a system parameter setting module a106, an inspection data managing module a107, and a diagnosis report processing module a 108;

the query module A101 is used for a user to query prestored information through preset relevant rules, wherein the relevant rules comprise preset numbers, storage dates and/or attributes of the information, and the attributes comprise report numbers, examination types, examination parts, examination doctors, submission departments, submission doctors and examination equipment;

the preset number comprises a medical record number and a check number. All numbers in the system are unique in the system and do not allow for duplicate values. In case of input of a repeated value, the system will prompt a corresponding error message. The length of each type of number is fixed and consists of 0-9 numeric characters. The underdigit system will automatically complement the character '0' in the front. Thus, if the user enters a character other than between 0 and 9 while entering the numbering data, the machine will sound a "beep" alarm and the entered character will be invalid. If the length of the input character is less than the designated length, the character '0' is automatically complemented in front after the 'enter' key is knocked.

Many data in the system are related to dates, and all date data in the system are stored in a YYYY-MM-DD standard format.

A plurality of quick input methods are provided during input, and the method comprises the following steps:

12/21 or 12.21, denoted as 21 days 12 months this year;

21, indicated as 21 days of the month

78-12-21 or 78/12/21, indicated as 21/12 in 1978;

1.1.1 or 1/1/1, indicated as 1 month 1 day 2001;

the year, month and day separators in the dates can be one of '/', ' - ', and', or can be combined randomly, after the vehicle is input and is driven back, if an unidentifiable illegal date is input, an alarm sound can be given, otherwise, the complete date can be automatically supplemented.

The censorship department comprises a medical department, a shell, a traditional Chinese medicine department, an orthopedics department, an ENT department, a paediatrics department, an emergency department, a housing courtyard department of a medical department, a hand surgery department and a CT (computed tomography) room;

examination types include US, CT, DM, DR, DSA, ES, MR, and NM.

The system provides a method for comprehensively inquiring various data, the input of data inquiry conditions has a certain rule, and under the condition of various inquiry conditions, the relation among the inquiry conditions is a 'AND' relation. No input, the query condition is invalid, the input result must satisfy the current condition, multiple conditions are input, and the result must satisfy the input multiple query conditions

Each user in the system has password protection, the length is 10 bits at the longest, the user password can be modified at will, as long as the user logs in the system, no matter which functional module is entered, the user can press an F11 key, open a user parameter setting window, and then select a password changing page, and the operation method for changing the password is as follows:

inputting an original password of a user currently entering a system in an original password input box;

inputting the same new password in the input boxes of the new password and the confirmation new password; the password modification is completed.

When a system user registers a patient or writes a diagnosis report, some places need to input Chinese characters, some places need to input numbers, frequent input method conversion is troublesome, and different users are used to different input methods. Meanwhile, when a certain printer on the network is busy when a diagnosis report or an inquiry result is printed, the printer for outputting data must be changed at any time, so that it is necessary that each user can define the familiar Chinese input and can change the printer for outputting data at any time.

The user can click the 'Chinese input method' drop-down list to select the Chinese input method installed by the local computer, and can also click the 'output printer' drop-down list to select the printer installed by the local computer, and then the setting is saved, and the saved result is always effective for the user regardless of whether the user logs in again or changes the work site to log in.

In order to improve the security level of the system, the work responsibility of each doctor is determined, the illegal person is prevented from having an opportunity to change data, the workstation can be locked when a user leaves the workstation for a short time, the locked workstation can be unlocked only by inputting a correct user password, and the illegal person is prevented from modifying the data when the user leaves the workstation. There are two ways to lock: manual locking and automatic system locking.

Manual locking: in actual use, a user can lock the current workstation screen by pressing the key F12, and open the locking dialog box after locking, and the user can only input an unlocking password and cannot perform any other operation, and the dialog box can only be closed after inputting a correct user password.

The system is automatically locked: and after the time that the workstation is idle for one time reaches the time that the system is set to be locked, the system automatically locks the workstation. The locking time is determined by the default locking time of the system and the locking time of the user, after the default locking time of the system is set, the user cannot cancel the locking function, and only under the condition that the default locking time of the system is not set, the user can forbid the locking function.

the user defaults to the screen locking time: when the user leaves the system and the system enters an idle state, the system starts timing, and when the timing reaches the set value, the screen is automatically locked immediately, and the user can continue to use the system only by inputting the password of the original user. The screen locking time is effective for all users, each user can also independently lock the screen, if the user sets the screen locking time, the screen locking time is the time set by the user, if the user does not set the screen locking time (the user setting value is 0), the default screen locking time set at the point is taken, if the screen locking function needs to be cancelled, the value is set to be 0, but the setting of the user is still effective, and the user himself must forbid the automatic screen locking function at the same time to complete the prohibition;

report single coding number: the system automatically allocates a unique report number to each diagnosis report according to the test type, and the parameter can control the bit number of the report code;

WORKLIST operation date matching: when image equipment executes the WORKLIST inquiry, whether only a work list of a specified date is taken or all the work lists which are not checked are taken, and the date can be used as a matching condition when the system is inquired by the WORKLIS according to the parameter;

the working returns the number of records: when the image device executes the WORKLIST query, the parameter is used for controlling the maximum number of records returned by the SCP service program, and the default is set to 100.

Advanced parameter setting

Care must be taken to set advanced parameters in the system, and after setting, the parameters do not need to be changed under normal conditions.

Medical record number generation rules: the system allocates a medical record number (a numeric character string) for each patient to identify the medical record information of the patient, the medical record number can be input by a registered doctor or automatically generated by the system, and the parameter is mainly used for controlling the generation method of the medical record number;

initial medical record number: the first medical record number automatically allocated by the system is automatically increased in number later and is effective only under the rule of automatically generating the medical record number;

length of medical record number: the number of medical record numbers, the number of medical record numbers automatically allocated by the system or input by a user, and when the number of medical record numbers input by the user is insufficient, the character '0' is automatically supplemented in front;

check number generation rule: the system allocates a check number to the patient for each check, which uniquely identifies the check, and the check number, like the case history number, can be automatically generated by the system or manually input by the user, and this parameter is mainly used to control the generation method of the check number.

Checking the number of digits: checking digit number, automatically distributing by system or checking digit number inputted by user, and automatically supplementing character "0" when checking digit number inputted by user is insufficient;

maximum capacity of optical disc backup: in the 'backup filing' function module, when the diagnostic data is backed up to the optical disc, the parameter is used to control the data quantity of the optical disc which can be backed up at most when the optical disc is backed up each time;

optical disc backup buffer folder: in the "backup and filing" function module, when the diagnostic data is backed up to the optical disc, the system first transfers the data to a buffer folder, and then records the data in the folder into the optical disc, where the path of the buffer folder can be set.

An inspection data management module A107 for inputting images or characters to obtain target data;

the query condition input part can input simple query conditions only, and can also input any combination, including:

specifying the date of examination: inquiring date conditions of the registered data, taking the initial date and the ending date as inquiry conditions when options are checked, or taking the date (one day) of the 'date' input box as the inquiry conditions;

date: the inquiry condition is valid only when the 'specified check date' is not selected, which means that only the check registration data of the specified date of the input box is inquired, the date in the input box can be changed, and the inquiry result is returned;

name: the name of the patient is specified, only one character in the name can be input, and fuzzy matching is carried out during query;

sex: selecting the sex of the patient, optionally;

reserving a patient: checking the options, only inquiring the data of the reserved patient, or else, inquiring all the examination records;

and (3) checking type: the method can be selected or deselected for inquiring the inspection record of a specific inspection type;

patient type: either or not, for querying examination records of a particular patient type;

an inspection device: one or not can be selected for inquiring the inspection record of the specific inspection equipment;

and (3) fast searching: returning and displaying a query result according to the input query condition;

and (3) accurate searching: and opening a more detailed query condition input dialog box to accurately query the patient examination record.

The diagnosis report processing module a108 is configured to write contents of a diagnosis report and output the diagnosis report, and further includes:

reviewing the diagnostic reports of the previous and subsequent records;

and (4) auditing report: if the current report is not audited, the report can be audited, the audited report can not be modified, and the report can be continuously modified only by executing report rewriting operation by an auditor;

rewriting reports: if the current report is already audited, changing the report into a rewriting state cancels the audit;

and (4) modifying the report: opening a report compiling window and modifying the current report;

duplicate reports: copying the current report to a memory so as to paste the current report in a report compiling window;

and deleting the report: deleting the current diagnosis report;

printing: and printing out the diagnosis report, wherein the login user has to have the operation authority of printing the report sheet to print out the report.

The system has a visual and visual report writing template and can quickly generate an accurate diagnosis report by matching with a comprehensive diagnosis module library. Selecting an examination record in the image reporting function module may turn on a diagnostic reporting function to compile a diagnostic report for the currently examined patient.
