Three times the standard deviation, a statistical quantity. This deviation is applied to a system's mechanical measurements, which require statistical analysis of the data to determine the system's expected performance. If the data set is normal and randomly distributed, +/- 3 standard deviations from the mean will capture 99. 74% of the data. Statistically, 0. 26% lies outside of the +/- 3-sigma limits (2. 6 points out of a thousand).

A locus of motion. The HET Clinac has many axes: collimator, jaws, MLC, gantry, couch longitude, couch latitude, couch rotation, kV image source, kV image target, MV image target, and so forth. An axis can be calibrated, initialized, servoed, and otherwise controlled by the HET Clinac control system.

Used in DICOM to mean a continuous plan of treatment that includes beam parameters, device parameters, imaging instructions, a tolerance table, motion permissions, and two or more control points, as well as the treatment device to be used (such as the Clinac 2100 EX #3212); used generally in DICOM to mean both imaging and treatment beams. The terms "beam" and "field" often are used interchangeably; however, a beam is distinct in having a field and some images planned for that field.

1) La distribuzione spettrale di energia del fascio di radiazioni rispetto alla energia di radiazione. Qualità del fascio descrive la penetrazione del fascio attraverso il tessuto e il relativo assorbimento dell'energia in diversi tipi di tessuto. Qualità del fascio è spesso exp 2) particolarmente per i raggi x.

Equal dose distribution across the treatment field irradiated by the beam. In the Clinac, beam symmetry is monitored by comparing the dose distribution on symmetrically aligned pairs of collector plates in the ion chamber. If the beam is asymmetrical, the Equal intensity over the entire area of a beam's column. Symmetry is measured in the ion chamber and is controlled by the angle and position steering coils.
