This book is an accessory textbook of medical physics. It is composed of two main parts. Part one deals with laboratory experiments. Nine basic laboratory experiments in medical physics have been introduced in detail. People usually say that ¡°Tell me and I will forget. Show me and I may remember. Involve me and I can surely learn.¡± Laboratory experiments play an important role in improving the cultural and scientific qualities of students. Therefore we should pay more attention to laboratory experiments and perform every experiment very carefully. Part two deals with summary for each chapter and solutions for all problems of medical physics. R. P. Feynman (1918¡ª1988), Nobel laureate in Physics, once said, ¡°You do not know anything until you have practised.¡± And A. Sommerfeld (1868¡ª1951) told his student W. Heisenberg (1901¡ª1976) that ¡°Just do the exercises diligently. Then you will find out what you have understood and what you have not.¡± Your ability to solve problems will be one of the main tests of your knowledge, and therefore you should try to solve as many problems as possible. It is good practice to try to find alternate solutions to the same problem.
Medical physics is fun. Enjoy it!
