Two-axis apparatus with stationary positioning, rotating and/or scanning motion of point or line sources

摘要

An apparatus and method for simulating a radiation phantom so as to calibrate or measure performance of a gamma detection system. The apparatus includes a line bar configured to rotate around an axis of rotation, a source carriage configured to move linearly along the line bar and to hold an attached radiation source, and a fixture assembly configured to support the line bar, the fixture assembly being configured to attach to a patient bed.

1. An apparatus for simulating a radiation phantom so as to calibrate or measure performance of a gamma detection system, comprising:
a line bar configured to rotate around an axis of rotation; a source carriage configured to move linearly along the line bar and to hold an attached radiation source; a fixture assembly configured to support the line bar, the fixture assembly being configured to attach to a patient bed; a rotational motor configured to control rotational motion of the line bar around the axis of rotation; and a processor configured to control the rotational motor to rotate the line bar at a set angular slew rate.
