As Technology Expands, Medicine Often Benefits

Crunching The Numbers The human brain is a supercomputer unlike anything mankind has ever been able to design. Though technology doubles on itself every eighteen months, much how Moore’s Law describes, it has still yet to reach the potential of the mind. Still, it is ever advancing onward, and scientists believe a “singularity” will come. This singularity will be the point at which artificial intelligence surpasses human intelligence. Thankfully, this event horizon is still several digital twilight hours away. In the meantime, the kind of technological development seen in the 21st century is quickly optimizing medical understanding and procedures by providing practitioners the requisite tools. One of those tools is digital information compendiums kept in blogs and on niche-centered websites. The kind of information available to someone who knows what to look for is essentially endless, giving practitioners more treatment ammunition than ever. Additionally, as discoveries are made, they are more quickly disseminated.

How Health IT is Helping to Improve the Lives of Patients

Health IT has essentially created a new ecosystem that helps improve the lives of patients while also making life easier for physicians.  In the past, if a patient was sick or needed help with anything, they either had to make an appointment to see a doctor or drop in at the emergency room.  Patients can now, however, take advantage of the technology available to speed up care. It is now possible for patients to receive a remote area diagnosis by receiving a consultation via video chat.  Patients also have access to health wearables which can help monitor everything from heart rate to blood glucose levels.  The data from these devices can be sent immediately to health care providers to ensure a patient is an inadequate health.

The U.S. and the Changing World of Medicine

There is no doubt that as everything else is evolving with new technology, medicine is too. The issue is that in the US, our medical system is broken and the insurance companies are too rigid. Doctors and other medical personnel have managed to work even with these difficulties and still provide patient care that is excellent along with new techniques that are successful. With the advance of biomedical research, doctors will be able to better tackle health issues in ways that are cost effective. Automation is only one area where there is new technology coming to the fore. Because of this advancement, linear actuators are being used more often as opposed to hydraulic and pneumatic systems. They range in size from very small to very large ones. Aside from the changes that technology has seen, there are quite a few other reasons that have made these actuators necessary, such as the ever growing need for power assisted seating and motorized wheelchairs.

3 new ways technology is helping to advance medicine

Imaging Cameras improving cancer surgery Every year, 14 million people are diagnosed with cancer; of those, around eight million will die. Cancer is one of the leading causes of death worldwide; across the globe, doctors and scientists are fighting to reduce the number of cancer deaths by detecting cancer early and promoting new ways of battling it. In the past, imaging technologies such as radiography, magnetic resonance imaging, and computed tomography have proved vital in the fight against cancer, helping doctors to diagnose the disease quickly to increase the chance of recovery. Now, near-infrared fluorescence (NRF) has emerged as a new, powerful imaging tool in the battle against cancer. NRF imaging is used during surgery to enable surgeons to distinguish between healthy tissue and cancerous tissue easily. Surgery is a highly effective method of treating cancer patients, but its success rate depends largely on how much of the cancer is removed; if cancer cells remain in the body after surgery, the surgery’s success rate is greatly diminished. Advocates of NRF hope the technique will give surgeons greater visibility of cancer margins and increase their ability to remove cancerous tissue precisely. Companies such as andor.com are researching how we can implement…

Ultrasound wave propagation and parameters

Ultrasound waves are acoustic pressure waves that interact with propagation media. Ultrasound visualization is typically based on wave reflectance from regions with different acoustic properties. When a wave meets different acoustic media, part of it transmits further while others reflect. This happens due to different acoustic impedance. The ration between reflected and transmitted energy purely depends on the difference in acoustic impedance in both regions. As you can see each material can be characterized by its acoustic impedance Z which is equal to ultrasound speed v and material density r.

Using wavelet transform in biomedical engineering – heart signal analysis

As we mentioned before, wavelet transform is used to analyze short time and non-stationary signals. Since base wavelet function has to parameters – translation and scaling, it is possible to achieve good time and frequency localization. In other words, we can equally analyze slow signal and fast signal structures without losing resolution and so evaluate signal frequency characteristics and time dynamics. Heart signal analysis is one of the most common problem in biomedical engineering. Practically every part of ECG signal carries some sort of information about heart condition, possible pathologies, and deceases. So equally frequency and timing characteristics of ECG signal is important. As you know standard ECG signal consists of several typical waveforms like P-QRS-T where in P and T waves low frequency component dominates and in QRS mid and high. The common condition of hear is myocardial ischemia when blood flow through coronary arteries to heart is reduced what prevents receiving enough oxygen. This can damage heart muscle and lead to heart attack. In order to notice this pathology it is we need to analyze S-T segment of ECG waveform. Insignificant changes in signal can indicate ischemia. In order to find the variations in signal it is needed…

Automation In The Medical Field

The advancement in technology and medical automation has led to the increased use of linear actuators in the medical field that has continued to render pneumatic and hydraulic systems obsolete. The use of actuators will vary depending on their sizes that range from the tiny ones (2” strokes) to the large ones (24” stokes). Other than changes in technology, several other contributing factors have necessitated increased actuators in the health sector. Key reasons for the increased usage of actuators in the medical field First, the size of a machine is a factor to consider when deciding the technology to use. Actuators are appealing in size, especially compared to hydraulics that can yield a similar amount of strength. Secondly, when in action, actuators produce less noise as compared to pneumatic and hydraulic solutions. The hiss and gurgle sound found in pneumatics and hydraulics do not exist in actuators that have triggered their continued use.  The photo below is a sample of the actuator’s wheelchair. Another positive factor that has contributed towards the use of actuators is that they are precise. Pneumatic pistons can be positioned correctly at either full extension or retraction. Lastly, actuators have fewer moving parts implying that fewer…

Blue Laser – The New Alternative Treatment for Autism Care

Life as a human being is full of many unpredictable events. We always have the risk of getting numerous types of diseases at any time. Although health and medical’s technology have been growing in leaps and boundaries, many conditions remain uncured until today… A recent study has been shown that the blue laser has the power to cure autism. A research group from MIT had carried out an experiment where they shined the blue laser onto a live mouse brain directly. They discovered that the gamma waves are triggered in the mouse’s brain, where the primary brain wave can be used to cure autism. The research group called the specific neurons that trigger gamma waves “Fast-spiking interneurons.” Although scientists have known about gamma waves for over decades, they’ve lacked the technology to prove their theory. They also mentioned that people with autism are mainly caused by the inadequate gamma waves in their brains. One of the best solutions to overcome this problem is to trigger gamma waves in people with these psychiatric conditions as soon as possible! More research has to be done before the blue laser could cure autism in the future. [discovery]
