The Backbone and future of medicine

Biomedical engineering 

Biomedical engineering is where innovation meets human life. It combines engineering principles with medicine to tackle healthcare challenges. Imagine designing an artificial heart that keeps someone alive or creating a smart prosthetic limb that responds to brain signals. Biomedical engineers develop life-saving MRI machines, wearable health trackers, and even 3D-printed organs. They are not just building machines; they are building hope. They improve how we diagnose, treat, and heal. This field is ideal for those who want to use technology to directly impact lives.

Machines of Life 

In order to diagnose patients and create successful treatment regimens, medical imaging technologies like MRIs, ultrasounds, and X-rays are essential. Doctors would have a very difficult time correctly identifying illnesses or keeping an eye on interior structures without these tools.

A radiologist with over 25 years of expertise gave me the chance to learn from him during my observership at a prestigious hospital. He thoroughly described the operation of various imaging equipment. He explained the usefulness of each modality and how computer algorithms and technological developments enable the production of both standard and 3D images, which can precisely depict organs, muscles, and tissues to within a millimetre.

The Xray Machine 

X-ray machines are like medical eyes that see beneath the skin. They reveal broken bones, hidden tumors, and lung infections in just seconds. They work by sending a beam of high-energy X-rays through the body. Dense materials like bones block more rays and show up as bright white, while softer tissues appear in shades of gray. This scientific process lets doctors diagnose problems without making a single cut. X-rays are one of the most powerful and painless tools in modern medicine. These images can then be modified and using complex computer algorythims can even be turned into 3D images , during my observership i luckily had the chance to view one , in action , with the model of a heart .

- The picture beside shows how 2D grayscale images are captured using an X-ray-based imaging technique, like a CT (Computed Tomography) scan. These images go through computer programs to create a detailed 3D model of internal organs, such as the heart. With this 3D model, doctors can view exact cross-sectional "slices" of the heart. This allows them to check specific areas of concern, especially where a patient has a history of heart issues. This leads to better diagnoses and personalized treatment planning. A remarkable aspect of these 3D reconstructions is their accuracy; they can be precise to within a millimeter, providing life-sized, realistic images of blood vessels, heart valves, and other crucial structures.


The MRI

MRI machines are like advanced cameras for the human body. They reveal what’s hidden deep inside without any cuts or radiation. Using strong magnets and radio waves, they align hydrogen atoms in your body and measure the signals those atoms send out as they relax. The result is clear, 3D images of soft tissues like the brain, spine, and organs. MRIs help doctors identify tumors and detect nerve damage. They provide a safe, detailed view for diagnosing and treating patients accurately.

- MRI scans of the skull, presented in both 2D cross-sectional and 3D reconstructed views, can significantly aid in diagnosing brain function abnormalities, detecting cancerous cells, and identifying tumors. These detailed images support clinicians in planning and personalizing effective treatment strategies."






In my next blog post, I look forward to sharing more about the types of patients I’ve encountered in the Emergency Room, how the ER functions behind the scenes, and the immediate treatments doctors often initiate upon a patient's arrival. I’ll also reflect on the fast-paced decision-making process and the importance of teamwork in critical situations. These stories offer a glimpse into the urgency, challenges, and rewards of emergency medicine

From Medicine to Machines: Discovering My Path in Biomedical Feild

As I began to ask myself questions about what to study and what genuinely caught my interest, I was lost in a sea of possibilities. I could, for example, study for a degree in medicine. I could work as a doctor, helping to treat and operate on patients, and positively impact patients’ lives. But then, I remembered something. Doctors, for example, give medications and perform surgery on patients, but what methods do and processes does the physician use to arrive at such decisions? What information, processes, and algorithms guide their decision-making? It was at this point that I found out about the hidden world—the world of biomedicine. It was a powerful yet simple answer, one that kicked off my interest in the world. I began my research and myself in the following months to look into potential options such as biochemistry, biotechnology, and biomedical engineering. I found the highly innovative nature of the fields that integrate science, technology and health to boost development of ...

The Emergency Room.

  My first day in the Emergency Room (ER) was intense, filled with diverse and unforgettable patient encounters. As an observer, I was excited but also apprehensive about what the day would bring. I quickly realized that the ER is a world of its own: fast paced, unpredictable, and crucial in saving lives. Case 1: Kidney Stone Emergency The first case I encountered involved a patient suffering from kidney stones. The patient was brought in by ambulance, clearly in distress, and complaining of severe left abdominal pain. Their symptoms included fever and shivering, which led to a red classification during triage, indicating the need for immediate medical attention. In order to alleviate the patient's discomfort, the doctors promptly gave them IV fluids and painkillers. I became aware of how important prompt intervention is in the emergency room after witnessing the team's quick and effective actions. Even though kidney stones are common, they can cause severe, incapacitating p...
