Cancer treatment typically involves surgery, radiation therapy, chemotherapy, hormone therapy or biological therapy. An oncologist may use one therapy or a combination of methods, depending on the type and location of the cancer, whether the disease has spread, the patient’s age and general health, and other factors.

Posted by admin on Nisan 5th, 2010
While today many medical-imaging needs are being met with traditional vacuum tube–based technology, large segments of the X-ray–imaging market are poorly served, and there is widespread demand for both performance improvements and cost reductions.

Gamma rays…
Are emitted from the nucleus to trim excess energy.
Tend to carry higher energies than X-rays, but this does not have to be the case
For example, after a larger energy decay particle (e.g. a beta particle) is emitted, the nucleus may still be slightly unstable (i.e., the atom [...]
