Electronics In Telemedicine
Majority of the Indian population is settled in rural locations where a clinical set up with proper facilities is almost non-existent. Even if by any remote chance, an individual is able to find one, reaching the facility will prove to be a tiresome journey. However, quality of the medical treatment cannot be assured as the medical facilities in most will not be equipped with latest machines and equipment, or the professionals will not be trained to operate them. In a scenario such as this ‘Telemedicine’ seems to be the answer to ease medical complications. The term Telemedicine refers to the use of telecommunications and information technology to d deliver healthcare services thereby ruling out the constraints of distance, time or physical inability to travel. There are three broad types of Telemedicine:
- Remote Patient Monitoring:Is a technology which enables a patient to use a mobile medical device to perform routine tests and send the test data to a healthcare professional.
- Store and Forward Technology: It is the technology of acquiring and storing the clinical details (image, data, video, etc) from the patient and then forwarding the details to other locations for evaluations.
- Interactive Telemedicine: It allows the patient andthe doctor communicate with each other beyond a clinical setup.
Telemedicine is a boon not only to the rural population but also senior citizens staying in urban locations. It saves time and money of travelling enabling a patient to stay indoors and get his/her health monitored by a specialist. It also enables a patient to procure multiple opinions on his/her health conditions without the trouble of travelling to different locations. It enables a general doctor to seek opinion of a specialist who might be in a different location. It allows flexibility to both the patient and the doctor.
Medical imaging in Telemedicine
Medical imaging is the process of creating images of the human body or an organ to study the functioning of the organ for the purpose of diagnosis for example X-Rays, MRI scans, etc.Medical imaging has transformed medicine and it is an inseparable aspect of Telemedicine. While medical imaging was traditionally considered only as a diagnostic tool, today it has manifold functions which aid the physician in not only diagnosing but treating, managing and even predicting disease. The importance of medical imaging is only growing by leaps and bounds.
Needless to say, accuracy plays a pivotal role in Medical Imaging. The whole purpose of Medical Imaging will get lost if it cannot prove to give accurate results. In Telemedication particularly, where the physical presence of a medical practitioner is least the only dependable source that gains prominence is accuracyof Medical Imaging. The medical image needs to have sharp visualization to ensure correct diagnosis and prediction. A slight amount of ambiguity in the image can lead to a precarious condition in the patient. It might lead to incorrect diagnosis which will further lead to wrong treatment which might aggravate the disease or give rise to a new disorder in the patient.
Similarly, it is exponentially important to provide real-time characteristics to aid the doctor in correct diagnosis.
If it is a video then it is very crucial that the streaming or the recording of the video happens in real-time.
A slight delay might cause irreversible damage to the patient.
CoreEL Technologies has developed a host of H.264 digital Video Codec IPs targeted for medical applications.
Benefits of H.264 Intra Frame Codec for Endoscopy:
