Abstract: Advancements in data transmission has allowed radiologists at a given workstation anywhere in the world to send and manipulate any digital information. Wireless networks have been gaining popularity as a result of advancements that has solved security issues that have confined with the use of wireless technology in low-cost applications. This paper discusses an approach for transmission of medical images obtained from various imaging modalities and its remote transmission. The purpose is to study the existing method of medical image transmission over wired network and the proposed method here uses wireless network for the transmission of medical images to remote location. Remote transmission of various imaging modalities like Computed Tomography (CT), Magnetic Resonance Imaging (MRI) and Ultrasound (US) is done. The authentication allows user who are authorized to access the data. Security is provided through the process of encryption and decryption of data. The input is given as a DICOM (Digital Imaging and Communication in Medicine) image from source and is compressed and encrypted at source. The encrypted DICOM file is sent to destination over the network. Once the file reaches its destination, it is decrypted and decompressed. This implementation is done using Java programming language. Medical images are transmitted to doctors Laptop/I pad from source to destination over distributed network. Thus application may be hosted from a single system accessed by many others. A client/server architecture is an example of a distributed network where the server is the producer of a resource and many interconnected remote users are the consumers who access the application from various networks
