Quick Reference

Biomaterials

Natural or synthetic materials engineered to interact with biological systems for medical purposes, including implants, drug-delivery carriers, and tissue scaffolds. They must be biocompatible, meaning they do not provoke harmful immune responses.

Medical Imaging

Technologies that create visual representations of the interior of the body for clinical analysis and medical intervention. Major modalities include X-ray, CT, MRI, ultrasound, and PET scanning.

Tissue Engineering

A multidisciplinary approach combining cells, engineering methods, and biochemical factors to create functional biological substitutes that restore, maintain, or improve damaged tissues or whole organs.

Biomechanics

The study of the mechanical principles governing biological systems, including the forces ($F$), stresses ($\sigma$), and motions acting on the musculoskeletal system, cardiovascular system, and other organs.

Bioinstrumentation

The design and development of electronic and mechanical devices used to measure, record, and process physiological signals from the body, such as electrical activity from the heart or brain.

Biocompatibility

The ability of a material to perform its intended function in the body without eliciting an undesirable local or systemic immune response, toxicity, or rejection.

Prosthetics and Orthotics

The design, fabrication, and fitting of artificial limbs (prosthetics) and external support devices (orthotics) to restore function and mobility for individuals with limb loss or musculoskeletal impairments.

Drug Delivery Systems

Engineered methods for transporting pharmaceutical compounds to targeted locations in the body with controlled release rates, improving therapeutic efficacy while minimizing side effects. Pharmacokinetic modeling uses equations like $C(t) = C_0 e^{-kt}$ to describe drug concentration over time.

Neural Engineering

A specialization focused on understanding, interfacing with, and modulating the nervous system, including the development of brain-computer interfaces, neural prostheses, and neuromodulation devices.

Regulatory Affairs and Quality Systems

The processes and standards governing the design, testing, manufacturing, and marketing of medical devices and therapies to ensure safety and efficacy, overseen by agencies such as the FDA and EMA.
