And Then I Thought is a collection of epiphanies experienced and recorded by the author in the course of navigating his way through the greatest adventure of all-this trip we call life. A prescription for enjoying a conscious and meaningful existence, the insights will raise awareness and encourage deeper appreciation of the voyage. Love is the energy that fuels the universe. See it as limitless, rather than scarce and exclusive. A sense of wondrous serenity fills the space when things unfold magically. From page 88 Attitude, not circumstance, determines destiny. From page 120

Megavoltage electron beams are an important treatment modality used in modern radiotherapy. They often provide a unique option in treatment of superficial tumors that are less than 5 cm deep. The most clinically useful electron beams have energies ranging from 6 MeV to 15 MeV. The principal applications of electrons are: (a) in the treatment of skin and lip cancers; (b) in chest wall irradiation for breast cancer; (c) in administering boost doses to nodes; and (d) in the treatment of head and neck cancers.This work focuses on the commissioning and QA of two types of treatment planning systems...

The development of three dimensional conformal radiotherapy (3D-CRT), in which the high-dose volume matches the target volume and avoids normal tissues, has been a major theme for improving the physical basis of radiotherapy. Intensity modulated radiation therapy (IMRT) is the most advanced form of 3D-CRT. As with medical imaging, its development requires the professional activity of physicists and engineers. This study carried out in Ayadi Almostkbal Oncology Center - Alexandria, Egypt. All Dosimetric measurements were carried on siemens linear accelerator (ARTISTE) which produces photons...
