  3. Main Application of IoT in medical field

    In the hospitals and also in various other field of health sector the main challenge faced is the storing of medical data, at the most for X-ray, images and other related pictorial data. At the date many of the Healthcare locations are having their own Picture Archival and Communication Systems (PACS) due to this they are archiving the records related to any of patient. As it is beneficial but it also consists of one drawback namely the high cost for storage, it goes up to billions of terabytes of the records. As the solution for this issue have also been discovered that is the cloud which provides storage-as-a- service. As a result, many of the specialists can see the x-ray of their patient at any of the location via INTERNET.

    Figure 3: Functional Platform of Cloud Computing There has been a lot riding on the cloud and both

    Microsoft and Google are investing heavily in the technology [2]. But technology for the sake of it and without any specific implications is going to be counterproductive in the healthcare Industry. The two examples mentioned are just a minute part

    which has been utilized but for sure in the upcoming duration there would be more sectors in healthcare would access this (cloud) in the healthcare. The main motive of healthcare organizations is to provide a proper care, high technology in short, the business for the betterment of the people.

    Rather than offering the cloud as a cover to just earn money in healthcare industry they should provide a time to spend of its beneficial part which can help to develop the healthcare system and should offer in that manner or else the cloud accessing level would be low only in the healthcare sector as compare to other service sectors.
