In medical world, radiation oncology is uniquely positioned itself as the "High Tech Medicine". Radiation oncology has made tremendous progress for the past decade by merging high energy physics, computing technology, and advanced radiation calculation algorithms along with many new inventions of delivery techniques. Improvement made by this medical specialty not only provides substantial cancer survival outcome but also reduce the patient complication treated from the conventional cancer care methods. Integration of radiation therapy technologies to manage tumor control certainly creates important scientific interests with modern science.

The main focus of this special issue will be focusing on the new development in cancer treatment, quality control, treatment techniques, and radiation dosimetry with related topics. The special issue will become an international forum for researchers to summarize the most recent developments and ideas in radiation oncology, with a special emphasis given to the clinical progress with new technologies. Potential topics include, but are not limited to:

• Clinical trials and outcome research
• New technologies development and implementation
• Treatment delivery techniques
• Disease-specific treatment discussion
• Radiation dosimetry analysis
• Radiation protection, shielding, and design
• Clinical therapy physics review and applications
• Molecular imaging application in radiation therapy
• Medical imaging
• Professional issues in medical, clinical, and biomedical physics
• Radiobiology
• Quality control and assurance
• Computing algorithm and optimization
• Quality of life analysis
• Radiation safety
