| WEPRO096 | X-ray Radiation Source for Low Dose Angiography based on Channeling Radiation | 2186 |
|
||
| Angiography is one of the most reliable and contemporary procedure of the vascular system imaging. X-ray spectrums provided by all modern medical angiographs are too broad to acquire high contrast images and provide low radiation dose at the same time. The new method of narrow X-ray spectrum achieving is based on the idea of channelling radiation application. The X-ray filters used in this method allows eliminating the high energy part of the spectrum and providing dramatic dose reduction. The scheme of the facility including the X-ray filter is discussed. The results of the spectrum analysis for the channelling radiation source and typical angiography X-ray tube are discussed. Doses obtained by the water phantom and contrast of the iodine agent image are also provided for both cases. | ||

| WEPRO097 | The Base Parameters of the Compact 27 GHz Electron Linac for Medical Application | 2189 |

A compact and light-weight electron linac is attractive for a number of medical applications including intra-operational and cyber-knife systems. The design of such an accelerator can nowadays be based on using of a powerful high-voltage high-frequency gyrotron which can provide now in pulsed regime a peak power up to 15 MW at the frequency about of 30 GHz. Taking into account this possibility, the paper presents the results of design and numerical simulations for the electron beam dynamics in a linac with the operating frequency of 27 GHz. Designed linac consists of two parts: gentle buncher and main accelerating section. The beam bunching is complicated at 1 cm wavelength because high energy about 2 MeV is necessary for beam injection into the main stage with v/c=1. Beam dynamics simulations are held using BEAMDULAC-BL code*. The electrodynamics of accelerating structure based on biperiodic structure is presented. The electron gun simulation is also discussed. The RF feeding is planned to be realized using a gyrotron to be designed in IAP RAS. The gyrotron is capable to produce 2 MW peak RF power in pulses with pulse duration 400 μs and repetition rate 10 Hz.
