CHAPTER 1

1 THE APPLICATION OF INFORMATION TECHNOLOGY IN MEDICAL AND MEDICAL IMAGING

1.1 The world

1.1.1 Non-filmed X-ray

With the California Center for Community Health, a not-for-profit hospital group in California, a recent change to a non-filmed environment has brought a lot of economic benefits, given the traditional approach Imaging such as x-rays, MRI, and ultrasound on expensive and time-consuming films Two years ago, the organization switched to a system that allowed medical images to circulate on the Web so that technicians, doctors and medical staff from anywhere could access it [1]

Figure 1: X-ray images are digitized

(Trud)

Today, for many countries, the term "telemedicine" is no longer in the field of science fiction but has become familiar and in the near future, telemedicine will spread throughout the world In fact, in recent years, some countries (including our country)

have started to apply remedial measures remotely, healing through the Internet, mobile phones, even though waves form…

Currently, many national health systems have implemented a "telemedicine" program that includes remote diagnostic and therapeutic services with the help of state-of-the-art communication technologies Russia is leading the way in the widest and most comprehensive implementation of this program Since 1991, governments at all levels and authorities have adopted the "telemedicine" through telephony This allows any on-site physician, even in remote areas, to instantly contact leading medical professionals not only within a country but also across the country Consult with well-known experts in many fields around the world In Russia, at the end of the Soviet era,

a large amount of fiber was installed in the fiber optic communications system that was not used at full capacity The satellite communication system also has an abundance of transmission lines And they have been utilized for the program

"Telemedicine" [2]

1.2 Vietnam

In Vietnam, most hospitals have not applied image automation technology from the x-ray, ultrasound on the server, but mainly connected to digital printers, to print black and white photos For the patient, want to save to copy to USB and then copy to computer Some hospitals still use old x-ray machines, without a digital x-ray machine However, a number of hospitals have experimentally transmitted MINI-PACS in a LAN or Intranet

Figure 2: The connection model of online television project of Viet Duc Hospital was constructed in the period of 2013 - 2015

(Viet Duc Hospital)

1.2.1 City

X-ray automation, ultrasound on a central database is one of the most popular computer applications in PACS and Telemedicine networks Many countries have applied the transmission of signals from the X-ray machine to the operating room orthopedic surgery, in Vietnam only a few medical institutions apply that method, one

of the few It is the largest hospital in Hanoi such as Viet Duc Hospital, 108th Central Military Hospital, and Huu Nghi Hospital Smaller hospitals such as the K Institute, the National University Hospital are just testing the PACS system, and the HIS (Hospital Information System) is still incomplete

In 2015, Huu Nghi Hospital was chosen by the Ministry of Health as a pilot site

to build the first "filmless hospital" model in the whole country In 2018, the effectiveness of the hospital was studied and applied by some hospitals Filling the image into the PACS system has enabled the quality of magnetic resonance imaging (MRI), CT scanner, digital X-ray, ultra humidity to become sharper, longer storage times, and more It is convenient for doctors to follow and diagnose diseases quickly, accurately, accessible anywhere The use of film and chemicals to diagnose diseases also reduces the cost of printing films, avoids toxicity to health care workers when they are not exposed to chemicals, prints daily film and improves pollution

environment Moreover, the results are also saved on the patient CD, reducing waiting time for the results

1.2.2 Remote areas

In remote and isolated provinces, not only have information technology be used

in imaging diagnostics but the facilities and medical equipment of hospitals are still lacking and not modern Particularly, Moc Chau General Hospital - the largest provincial hospital in Son La province has not used electronic medical records

2 TREND IN THE FUTURE

Technology 4.0 is the 'smart spice' for hospital management FPT Chief Executive Officer Bui Quang Ngoc said that the emergence of technology such as AI would help Vietnam's health care industry become more modern and attractive Mr Bui Quang Ngoc: "The fourth industrial revolution has been talked about Last year, the concept was not as uniform as the previous three However, that does not matter The main concern here is the emergence of new technologies that can be applied in many industries, including healthcare For example, virtual assistants can chat, counsel patients automatically without the need for human assistance, or use artificial intelligence, large data analysis to assist the physician to diagnose the disease as well

as appropriate prescribing counseling; Cloud computing allows for fast, easy-to-use software leasing, which is suitable for small and medium-sized hospitals There are a number of pioneering hospitals that use technology solutions 4.0 There are very few

So the land for the application of 4.0 technology in the Vietnamese health sector is still very large " [3]

2.1 Telemedicine

There are two major developments in the medical world from a distance One is the study of network organization and transmission The medical data, medical texts including audio, images, etc are processed and operated by telephone or local area network, internet, television, optical cable The second direction is Developing data management software to develop a hospital information management system, storage, processing, database, audio and visual systems for diagnosis and treatment telemedicine and other data from imaging equipment such as ultrasonography, radiography, CT scanner, nuclear magnetic resonance imaging, etc Many countries have built networks with storage, processing and transmission systems or digital video processing and transmission networks Such networks are used in many fields at hospitals, research institutes and universities, which can be connected to many other remote centers via telecommunication lines The most applied areas are Telemedicine, Telepathology, Telemedicine Imaging and Remote Medical Care, Home Health Care for Chronic Patients, or Outpatient Treatment Telemedicine will definitely grow rapidly, as with the development of information and communication technology, the cost of these services will decrease dramatically They are becoming more and more familiar with the technology and increased use these services

Figure 3: The equipment from the remote diagnosis

In 2007, the Help International “family doctor” model was first founded in Vietnam, followed by many similar models, such as

Homecares, Jio Health, Vina Healthcares, etc transmission network, and data management software, one of the important systems for automating digital imaging to the central database in medical imaging, Future, medical distance will grow further

Figure 4: Number of outpatient visits at healthcare facilities in Ho Chi Minh City

(Health Department of Ho Chi Minh City)

The number of outpatient visits is increasing year by year, particularly in the period 2010-2017, increasing from 24,262,490 to 36,286,624, an increase of approximately 50% compared to 2010

CHAPTER 2

1 PACS (Picture Archiving and Communication System)

1.1 Concept

PACS (Picture Archiving and Communication System)is a medical imaging and storage system in which images are taken from medical devices such as ultrasound, X-ray, CT, nuclear magnetic resonance imaging (MRI) With the current format, DICOM images are stored in servers and transmitted to computers for diagnostic and therapeutic purposes

The information storage and retrieval system are responsible for managing the storage, transmission, and receipt of images on the computerized information network

of the Diagnostic Imaging Unit or the Hospital, in which images are taken From the devices: ultrasound, X-ray, tomography, nuclear magnetic resonance with the current image format is DICOM is stored at the server and transmitted to the computer

in the diagnostic department images and faculty in the hospital for the examination, diagnosis, and treatment Other PACS RIS is the management, storage, transmission and receipt of images on the network without regard to the text data such as patient details, number of screenings, medical records, treatment, etc

1.2 Role

PACS has two basic roles: storage and transmission of images However, it is only a system for managing, storing, transmitting and receiving images on the network without integrating textual data such as patient details, treat

Digital Imaging and Communications in Medicine (DICOM) is the standard for handling, storing, printing and receiving images in medicine This standard includes defining the file structure and the communication protocol The communication protocol is an application protocol that uses the TCP / IP platform to communicate between systems DICOM files can be exchanged between systems as these systems are capable of receiving images and patient data in DICOM format [4]

2.2 Role

Image standards DICOM provides protocols for combining devices from different manufacturers in the image processing process In addition to providing the image, a DICOM image file also provides textual information such as patient information, the type of camera that produces the image

2.3 Main function components

Figure 7: Main function components of DICOM

CHAPTER 3

1 THE OPERATION OF THE AUTOMATION SYSTEM

1.1 The operation

In the HIS (Hospital Information System), there are PACS and RIS connected systems, though different in terms of data display, when PACS only displays images in DICOM format, while RIS manages and saves them excluding image files, accompanied by detailed patient information

The input will be images taken from medical devices managed by the HIS / LIS administration department, and the images will then be processed through the DICOM standard

Images can be exchanged based on two models: Network Exchange - Online Streaming and Interchange Storage - Offline Streaming

Exchange-based online communications based on DICOM's upper layer services and TCP / IP (Transmission Control Protocol / Internet Protocol)

Exchange-based offline news delivery based on Dicom's basic file-mediated packet-based packet-based physical media and intermediate file format With these two models, during the exchange can be optional data security However, in Vietnam, most of the new hospitals are exchanging image information in physical form, copy to USB, only big hospitals such as Viet Duc Hospital, Huu Nghi Hospital has tested and implemented This automated system has been in the last few years

After the encryption or compression process (depending on the image characteristics) Move backup all the patient image data stored on the server automatically triggers the distribution of clinical information, remote diagnosis, diagnosis, photo-based treatment through the hospital information system In addition, from the central database, medical staff can still print DICOM images on paper or export data to CDs / DVDs, which can be in two-dimensional (2D) or (3D) three-dimensional formats

Here are some pictures at the National University Hospital on the transfusion of fetal ultrasound images through physiological mediating equipment in, from ultrasound to computer for diagnosis and presentation by physicians Directly on the television screen so patients can watch live

management based

on the medical network model)

1.2 The relationship between DICOM and PACS

DICOM's main role is reflected in PACS The current "mini PACS" and "partial PACS" approach make DICOM adaptable to a variety of device interfaces In an imaging device environment with a variety of manufacturing technologies, this avoids arbitrary or proprietary interfaces for devices This leads to reduced complexity and cost in device connectivity, and simplifies the service [5]

1.3 Limited in line speed

Although X-ray automation and ultrasound on the central database are excellent diagnostic measures in imaging, with patient overload in some hospitals, data transfer rates may be slow This is especially true for systems that are under testing and are not yet complete

CHAPTER 4

1 CONCLUSION AND RECOMMENDATION

1.1 Experience and benefits learned from the study of the topic

Throughout the course of the project, the benefits and experiences learned are how to select a topic, find information and synthesize information

Extend the understanding of databases, information systems and the development of digital technology

1.2 Conclusion

The study sought to answer three research questions This section will summarize the answer to a question obtained through the results of the study

The first question is what is the benefit of automating X-ray imaging on a central database during a medical examination? There are three main benefits that the X-ray and ultrasound automation systems provide the central database

The economic benefit of saving money on film and chemicals

Health benefits when health workers are not exposed to chemicals during X-ray film cleaning

Improving medical services and technology development is the cornerstone of Telemedicine
