I recently came out with a three-volumes handbook of Nuclear Medicine and Molecular Imaging for Physicists.
This set is split into three volumes, respectively titled: Instrumentation and Imaging Procedures; Modelling, Dosimetry and Radiation Protection; and Radiopharmaceuticals and Clinical Applications.
Volume one, Instrumentation and Imaging Procedures, focuses primarily on providing a comprehensive review into the detection of radiation, beginning with an introduction to the history of nuclear medicine to the latest imaging technology. Volume two, Modelling, Dosimetry and Radiation Protection, explores the applications of mathematical modelling, dosimetry, and radiation protection in nuclear medicine. The third and final volume, Radiopharmaceuticals and Clinical Applications, highlights the production and application of radiopharmaceuticals and their role in clinical nuclear medicine practice.
A link to more information about all volumes can be found below. It is also available also as en e-book. Hope you find it interesting.
