tissue dose मीनिंग इन हिंदी

Although not currently being used for BNCT, the neutron irradiation facility at the MITR represented the state of the art in epithermal beams for NCT with the capability of completing a radiation field in 10 15 minutes with close to the theoretically maximum ratio of tumor to normal tissue dose.
By using the line-emissions of Ag at 22.1KeV, for example, the detector pixel would receive ~ 50 % of the X-ray fluence instead of 5 % so that the tube brightness can be reduced by an order of magnitude with dimming the detector fluence while the tissue dose is reduced by a factor of 19 . Additionally, as shown in Fig . 2.5 where the kVp of the tube can be increased from 25 to 80 or 100kV without altering much of the X-ray spectrum in a transmission X-ray tube that gains the tube efficiency by ( 80 / 25 ) 2.1 = 11.5, or a gain of another order of magnitude.
