Medical Technology
Medical technology refers to a diverse array of computerized devices and systems designed to assist healthcare professionals in diagnosing and treating medical conditions. It plays a critical role in health technology by collecting and processing patient health data to generate informative reports that aid in clinical decision-making. Common tools in this field include diagnostic devices like electroencephalograms (EEGs) and medical imaging systems such as X-rays. These technologies enable doctors to detect conditions that are not immediately visible or obvious, facilitating precise diagnoses.
In addition to diagnostic applications, medical technology also encompasses treatment tools ranging from simple aids like bandages to complex devices like implanted monitors that track heart rhythms. The development and approval of these medical devices involve rigorous testing and oversight from organizations such as the U.S. Food and Drug Administration (FDA) and the Medical Device Innovation Consortium (MDIC). The ongoing evolution of telemedicine exemplifies how medical technology has expanded access to healthcare, allowing remote consultations and data transmission for diagnosis and treatment recommendations. Furthermore, advances in 3D printing technology may one day enable the creation of personalized organs, potentially transforming the future of transplant medicine. Overall, medical technology continuously evolves, offering innovative solutions to enhance patient care and outcomes.

FIELDS OF STUDY: Applications; Information Systems
ABSTRACT
The field of medical technology encompasses a wide range of computerized devices and systems that collect information about a patient's health, process it, and produce reports that can be interpreted by doctors to help them decide what treatment to recommend. Medical technology focuses on the diagnosis and treatment of medical conditions and is considered part of the broader field of health technology.
Computerized Diagnostic Tools
Devices that help doctors diagnose health conditions are a common form of medical technology. Some medical conditions are obvious to even an untrained observer, such as a gunshot wound or a severed limb. These conditions require little diagnosis because it is immediately apparent what is wrong. Other diseases and conditions, however, can be very difficult to detect and identify. Conditions such as low blood sugar, high cholesterol, or thyroid gland problems cannot be diagnosed visually. For such conditions, specially designed devices or procedures must be used to collect information about the patient's bodily processes. This is where medical technology comes in.
For doctors, everything the body does creates information. They must find ways to collect this information, analyze it, and use it to make educated guesses about the patient's condition. Part of medical technology involves clinical engineering, in which devices are designed to collect information about the patient's health. Some of these devices allow doctors to measure the signals created by the body, a process known as biosignal processing. For example, electroencephalograms (EEG) measure the electrical activity of the brain. Detecting abnormalities in these signals helps doctors diagnose epilepsy, sleep disorders, and brain tumors, among other problems. Doctors also use other types of medical imaging, such as X-rays. A person with a painful hand injury might receive an X-ray to determine whether or not any bones have been broken. Today, these X-ray images are usually taken and stored digitally rather than on film.
Treatment Tools
Medical technology can also be used to help treat a condition that has been diagnosed. Some types of medical technology are simple to understand and use. Think of bandages, crutches, and wheelchairs. Other types of medical treatment devices rely on more advanced technology. For example, tiny monitors can be implanted in the body to monitor heart rhythm.
The US Food and Drug Administration (FDA) must approve medical devices before they can be used in general practice. This requires extensive testing to show that the technology is unlikely to cause harm. Other bodies are also involved in this process, such as the Medical Device Innovation Consortium (MDIC). The nonprofit MDIC supports medical technology inventors and guides them through the FDA approval process. Groups such as this must balance the interests of doctors and the FDA with those of the medical technology industry in creating and marketing new devices. It is common for approval of medical devices to take several years. During this time, doctors and even some patients may be waiting for approval to use groundbreaking treatments. This places tremendous pressure on the FDA to move the approval process forward quickly and safely.
Medical Technology in the Twenty-First Century
Medical technology advanced rapidly in the twenty-first century, including artificial intelligence (AI), robotics, genomics, and nanotechnology developments. This technology improved patient outcomes, healthcare accessibility, treatment efficacy, and professional wellness.
The Internet has opened up new avenues of treatment for medical technology. The field of telemedicine, in which patients consult with doctors long distance, has grown dramatically. It is instrumental in bringing more treatment options to rural areas that may not have well-equipped hospitals or many medical specialists. In the past, telemedicine was restricted to telephone consultations. Diagnostic data can now be collected from a patient and transmitted over the Internet to a specialist. The specialist then uses it to recommend a treatment for the patient.
Advances in nonmedical technology have also raised the possibility of devices printing new organs or tissue structures designed for a particular patient. Today, computer models tell 3-D printers how to build a 3-D object using layers of materials such as plastic or ceramic. Devices use 3-D bioprinting to grow cellular structures according to dimensions defined by medical imaging scans. If a patient needed a healthy kidney, it would be possible to scan them to find out exactly what size and shape of kidney was needed and then 3-D print the kidney using tissue from the patient. This would minimize the risk of tissue rejection that comes along with traditional organ transplants. 3-D printing is commonly used to create customized prosthetics and implants perfectly formed to the patient's body.
AI and machine learning continue transforming healthcare by improving diagnostics, personalizing treatment, and optimizing hospital operations. AI-powered tools analyze medical imaging, such as MRIs and CT scans, with high accuracy that sometimes outperforms human radiologists. Machine learning models also assist in drug discovery, predict disease progression, and automate administrative tasks to reduce healthcare costs.
Many other technological advancements have supported the medical field in the twenty-first century. Surgical robots allow for minimally invasive procedures with greater precision and reduced recovery times. Robotic prosthetics and exoskeletons assist patients with mobility impairments, while automated systems streamline hospital workflows, from pharmacy management to disinfection. Genetic testing identifies hereditary risks for diseases such as cancer, while gene therapies offer potential cures for previously untreatable conditions. CRISPR-Cas9 and other gene-editing technologies may be used to correct genetic disorders at the DNA level. Nanomedicine utilizes microscopic particles to deliver drugs directly to affected cells, increasing treatment efficacy while minimizing side effects. Researchers are also developing nanorobots capable of detecting and destroying cancer cells at the molecular level.
