摘要： A radiation treatment system and method of commissioning the system, the system including a gantry, a radiation source operable to produce a beam of radiation, and a measurement device. The measurement device is physically connected to the gantry, and includes a multi-dimensional scanning arm, and a detector. The method includes generating radiation from the radiation source, passing the radiation through an attenuation block, and receiving radiation with the measurement device. The measurement device is positioned such that it is not in contact with water. Data is generated from the radiation received and the system is commissioned using the generated data to match system characteristics to a previously defined standard.

摘要： A voltage controlled oscillator (VCO 10) is disclosed in a "ring" configuration using two FETs. Two isolated voltage control terminals provide increased tuning bandwidth. The design uses an active feedback topology resulting in greater device size for higher output power and circuit Q.
