Varian TrueBeam Linear Accelerator, used for delivering IMRT Intensity-modulated radiation therapy (IMRT) is an advanced type of high-precision radiation that is the next generation of 3DCRT. [ 77 ] IMRT also improves the ability to conform the treatment volume to concave tumor shapes, [ 10 ] for example when the tumor is wrapped around a ...
The work of physicist W. W. Hansen was instrumental in the development of the klystron and was cited by the Varian brothers in their 1939 paper. His resonator analysis, which dealt with the problem of accelerating electrons toward a target, could be used just as well to decelerate electrons (i.e., transfer their kinetic energy to RF energy in a ...
The concept goes back to the work of Nicholas Christofilos. [23] Its realization is highly dependent on progress in the development of more suitable ferrite materials. With electrons, pulse currents of up to 5 kiloamps at energies up to 5 MeV and pulse durations in the range of 20 to 300 nanoseconds were achieved. [24]
(The Center Square) — Some Georgia governments are considering opting out of a bill that limits the increase of a homestead property's value to the rate of inflation.
A Florida couple is facing child abuse charges after local authorities say the man beat a child for nearly half an hour and his wife failed to help the boy.
[60] [61] After the merger Varian will continue to operate as an independent company and will retain its headquarters along with its 10,000 employees. [ 62 ] [ 63 ] In August 2024, Siemens Healthineers bought the diagnostic arm of Advanced Accelerator Applications that specialises in producing radioactive chemicals used for cancer scan for more ...
When we think of ultrasounds, most of us think of pregnancy. But this noninvasive imaging tool is also used to diagnose other health issues for people who get their periods — like misplaced IUD ...
