Types of Image Compression for Medical Imaging Essay

Databases, Electronic Healthcare Information Systems, Data Sets and Data Standards Patient data is crucial to healthcare practice. Having the ability to create, modify, delete, and view patient data is the most important aspect of healthcare. A vital storage mechanism to perform the above functions is a database. A database is essential in development of Electronic Health Record system A database is an organized collection of data saved as a binary-type file on a computer (Sayles, 2013). Binary-type files only contains ones and zeros so it is unreadable to end users. A database management system provides the ability to perform the functions mentioned above. Many vendors are available in the marketplace for different kinds of database

Medical imaging is used to create visual images of the interior part of the body so that it would be easier to examine, diagnose & treat patients without the need of surgical processes. This process is used to see what is beneath the skins and bones to find any abnormalities present.

The advancement in technology has rapidly transformed the world today, and the increase in the number of web-enabled devices has completely changed peoples ' lives especially the way they communicate. Electronic Health Record system, which is a digital copy of a patient’s medical history is one of the revolutionary ideas that have come with this advancement. Electronic Health Records (EHRs) are instantaneously updating records that are patient-centered designed with the aim of providing real-time information to the authorized users (Cohen, 2010). It contains all the patient’s information that is in the hand of the medical providers including their medical history, treatment dates and types, immunizations conducted to the patient and their dates, radiology images and all the laboratory results from the tests conducted in the past. All this information is held in a digital format and can only be updated by authorized users who are stationed in the medical facilities. Electronic records are designed to make it easy for different health providers and organizations to share patients’ information which streamlines their operations since all the necessary information and history can be accessed from any location at any time.

being attacked, encrypt it with a secret key to obtain an encrypted bit stream . For that AES encryption is used. After AES encryption, will embed at the fourth bit position of . Some related information about the mosaic image generation process into the mosaic image for use in the secret image recovery process are also embed at the last fourth bit position of . Such information, described as a bit stream I like M, includes the following data items: 1) encryption key; and 2) total length of before encryption. After all this process Target image with mosaic image, residual value and all information that required to recover original image are transmitted to receiver

The rapid growth of the Internet (World Wide Web) has been a major force facilitating and allowing hospitals in the U.S. to send images (i.e., X-rays, Ct scans, MRI scans, and ultrasound) over the internet to doctors/skilled workers overseas who specialize in reading/interpreting diagnostic medical images. This reduces the workload on medical specialists in the U.S., cuts costs, and is effectively faster. Some of these countries are on the opposite side of the globe, thus the images could be interpreted while it is nighttime in the U.S. and be ready for the attending physician when he/she arrives for work the following day. In addition to developments in communication technology, a major innovation in transportation

Table I displays six solid binary images along with their corresponding compression ratios. On considering Run-Length coding, the alternative encoding scheme produces better performance than the other encoding scheme. On an average, the proposed algorithm performs well on comparison with the standard Huffman coding algorithm by approximately 1.58%.

In radiography, picture archiving and communication system enables the capture, storage, retrieval and sending of digital

The articles by Branstetter, Bartholmai and Channin (2004) and Kohli, Dreyer and Geis (2015) make an important contribution to the knowledge base of radiology informatics. The overall delivery of health care has benefited greatly from the technology explosion that has affected almost every industry. This benefit has been highly visible in the practice of radiology. The introductions of radiology information systems, voice recognition dictation systems, and picture archiving and communication systems (PACS) led to significant advancements in workflow efficiencies. To this end, both articles examine informatics innovations of the past several decades that have immensely enhanced

Goal of coding theory is different to data hiding method even though both methods use the error correction codes [23]. In coding theory, syndrome equation in the first stage of decoder block is used to detect and correct error which is not expected in advance at the encoder block, whereas in data hiding, syndrome is used to choose proper coefficients to insert a watermark signal and decrease distortion. In the embedding process, by choosing proper e(x), some of the host image bits are modified intentionally.

Picture Archiving and Communication Systems (PACS): capture and store medical images such as x-rays, Computerized tomography (CT) scans, Magnetic Resonance Imaging (MRI) scans, and other medical diagnostic images (Glandon et al., 2014).

Every single Medical Image is saved in DICOM file format. Therapeutic Imaging Equipment creates DICOM documents. Specialists use DICOM Viewers, Computer Software applications that can show DICOM pictures, to analyze the discoveries in the pictures. DICOM documents contain more than just pictures. Each DICOM record holds Patients data (name, ID, sex and DOB, etc.), essential procurement information (e.g. Modality, Body region, etc.), and connection of the imaging study that is utilized to interface the picture to the medicinal treatment it was a part of.

Clinging our research onto (Ghazisaeedi, Mohammadzadeh, & Safdari, 2014), electronic health records is a digital version of a patients health record or chart. It is unique in its own way since information is readily available and restricted to a number of users hence maximum security. Information in it is confidential since it contains medical reports of patients which include their progress, reaction towards treatment and a record of treated illnesses. Not only does Electronic health records contain the information or date named above but also tests and results taken on patients over certain duration of time. As a result, this helps in correct procedures and work flow in health institutions.

Medical records comprises of a patients treatment history and relevant value information’s about a patients, the records provide written proof of a patients medical life over time. Such private and important informations should be securely kept and highly restricted. The storing and easily accessing of medical records is a very important part of managing in healthcare .Most healthcare organizations and providers are custodians of such records, and they keep this records either through the traditional paper recording system method or the revolutinalized computer based system called Electronic Halth Record System (EHR), or even used both methods of record keeping. Although the electronic health record is efficient and valued more than the

In the modern years, medical imaging has become a very important aspect of medical field since its origin in the 1970s Image processing has developed into an integral part of medical science ranging from PET scan to melanoma detection. Both the hardware and software required for Image processing have improved drastically resulting in today’s world where the medical professionals can recognise and diagnose thousands of diseases using this technology.

Modern medicine has undergone major advancements over the past years. One of these developments include the capacity to retrieve crucial information about the human body and its health beyond the use of manual diagnostic techniques. This is referred to as Medical or Diagnostic Imaging.
