This paper demonstrates the feasibility of using glass rod detectors for quality assurance
audit of radiosurgery units. Five radiosurgery units (3 Gamma Knife model C, 1 Gamma …

Though the 4 mm Gamma Knife helmet is used routinely, there is disagreement in the
Gamma Knife users community on the value of the 4 mm helmet relative output factor. A …

A radiophotoluminescent (RPL) glass rod dosimeter (GRD) and a small active volume‐type
silicon diode detector are used for the measurement of the output factors from Gamma‐Knife …

Dosimetry of the small radiation fields used in radiosurgery is often difficult because of finite
detector size and loss of lateral electronic equilibrium. However, small-field dosimetry is …

The measurement of absorbed dose as well as dose distributions (profiles and isodose
curves) for small radiation fields (as encountered in stereotactic surgery) has been difficult …

For stereotactic radiosurgery using the Leksell Gamma Knife system, it is important to
perform a pre‐treatment verification of the maximum dose calculated with the Leksell …

Purpose This quality assurance program is designed for stereotactic radiosurgical units,
gamma knife, to check and maintain the unit to preclude accidents and comply with current …

The Gamma Knife, Model B, treatment unit has no independent record and verify system, but
requires human intervention to double-check critical treatment settings prior to irradiation of …

To the Editor: Recent communication with other medical physicists at Gamma Knife Centers
in the United States and Europe has confirmed a troubling discrepancy in radiation …

Treatment units for radiosurgery, like Leksell Gamma Knife® and adapted, or dedicated,
linear accelerators use small circular beams of ionizing radiation down to 4 mm in diameter …
