3.1 Requirements Overview
Doctors see the patient sometime need to reference the past specific medical record, doctors need to know the patient medical treatment account in order to get the patient medical record, but doctors often only have patient medical record number or identity card number. At this point we have to use the medical number or identity card number to obtain patient all medical treatment records, but manually operation often spends a lot of time, therefore this query must to be programmable. So that doctors can quickly get all of the patient medical treatment records.
Traditionally in the establishment of the medical image record must spent a lot of time to generate the image file, and the process of generating the image file would generate a lot of wastewater to cause the environmental pollution, and these image files are often not easy to preserve. It often spends a lot of manpower and resources in the maintenance of these medical records, therefore we must allow all the image files can be electronicalized, making the establishment of medical image records to become a simple matter and not wasting resources.
When the doctor establishes the medical image record, doctor often needs to make the point mark on the image file, but sometime the doctor would make mistakes on the image file to lead the image file have
to be regenerated. Such editing of the image file is not only inconvenient and inaccurate, therefore we must provide users can do on-line editing of image files, allows users can do any editing on the image file, it would be no more difficult to edit the image file.
When the hospital has many patient medical image records, it is very time-consuming things to find the patient medical image records manually, therefore we must provide a function can quickly query the medical image record; the doctor could quickly understand the patient condition according to the medical image records. And the doctor could edit the medical image record for the demand, so system has to record every time modify to avoid the record will not be randomly changed.
Because Medical Image Maintenance System may be used on many record systems, the system has to be designed to easily join in other systems. Let Medical Image Maintenance System can perform its functions in the needed systems.
Through the requirement overview I separate the system into six main functions on the requirement functions; I will analyze every function in the next chapter.
Requirement Functions
1. Query patient medical treatment records 2. Establish patient medical image records 3. On-line image editor
4. Query and edit patient medical image records 5. Query medical image record editing history 6. Medical Image Maintenance System integration
3.2 Requirement Analyses
1. Query patient medical treatment records
Because doctors often need to search patient medical treatment account in order to do the medical record on the specific account or search specific medical treatment record, the requirement has to provide doctors can search all patient medical treatment records depending on the identity card number or medical record number. And medical treatment records must provide some information to facilitate the doctor obtains the medical treatment record he wants.
2. Establish patient medical image records
In order to electronicalize the traditional medical image paper records, the system has to design an electronic medical image record which combines with text and image, and the doctor can set the view permission on the medical records to protect the privacy of patients. On
image file part that I supply the basic medical template pictures to doctors to select as the image source or doctors can use the local side image files as the image source.
And system must automatically record some information about the uploader, the upload time, department, etc. The information can be the clues for the future investigations. When all records are electronicalized, we can reduce the manpower to maintain the paper medical records.
3. On-line image editor
The traditional editing the image directly mark the point on the image is not only inconvenient but also easy to damage image. When image files after electronicalizing, system has to provide direct on-line editing image features. Let the doctors can easily make modifications to the image, the functions of the editor must likes the functions of “Microsoft Paint”, doctors can make accurate modifications on the image, no longer be troubled by image of the damage.
4. Query and edit patient medical image records
In the past, access to the medical image records of patients, not only time-consuming and laborious. However, if all files are electronicalized, we can make the work of these queries to be completed by the computer.
Doctors need only enter a patient treatment account, medical record number or identity card number; the system can be based on these ID to get patient medical image records. It can improve the efficiency of
medical treatment to reduce the waste of manpower.
After doctors access the medical image records of a patient, the doctor may do additional modifications or statements to the medical image record. Therefore, the system must provide the doctor can remodify the medical image record in the future.
5. Query medical image record editing history
Because of the same medical image record may be remodified by the different doctors, the system must save every time medical image records to record the history of the modification. Let doctors be able to view the modification history of the medical image records to understand the change.
6. Medical Image Maintenance System integration
HIS system of NTUH has many record systems need to use medical image records, so Medical Image Maintenance System must has a characteristic which is that Medical Image Maintenance System can be easily established in other systems. Let capabilities of Medical Image Maintenance System can be used in various record systems.
