Accelerated fractionation is defined as reducing the overall duration of a radiotherapy regimen without a significant change in the size of dose per fraction or total dose. This is achieved by giving two or more fractions on some or all of the treatment days.
MedicalAn active filter is a type of analog electronic filter that uses active components such as an amplifier. Amplifiers included in a filter design can be used to improve the performance and predictability of a filter, while avoiding the need for inductors (which are typically expensive compared to other components). An amplifier prevents the load impedance of the following stage from affecting the characteristics of the filter. An active filter can have complex poles and zeros without using a bulky or expensive inductor.
