Doctors, particularly those with medical degrees like MBBS or MD, can collaborate with medical physicists and engineers in the design and development of medical equipment, although their roles may vary significantly. While general practitioners typically do not engage in this process, specialists such as radiation oncologists can play a crucial role, especially in creating treatment planning systems. In the U.S., medical physicists primarily focus on treatment rather than equipment design, which is mainly the responsibility of engineers. However, collaboration is essential for creating user-friendly workflows and quality assurance tools, as demonstrated by companies that integrate input from both medical professionals and engineers. This highlights the importance of interdisciplinary teamwork in the medical device development process.
