摘要： Focusing modules and methods are provided, which use a spatial light modulator (SLM) configured to yield a circumferentially sinusoidal pattern to derive focusing signals. For example, the SLM may comprise an optical chopper wheel made of a glass disc with a circumferentially sinusoidal pattern. The circumferentially sinusoidal pattern simplifies phase derivation from the focusing signal, providing a faster and more accurate estimation of defocusing. Signal detection may be carried out by a diode array that provides a more accurate signal faster, as well as a more differentiated analysis of the focusing signal than the one available by current technology.

摘要： An apparatus and method are provided for performing Quality Assurance of complex beams of penetrating radiation inside a patient. A detector with a transverse scintillating screen images the radiation inside a tissue phantom with high spatial resolution. The scintillator is comprised of a mixture of two or more scintillators emitting different spectra of light and having different characteristic responses as a function of the beam LET value. The optics relaying the scintillation output have variable transmission with wavelength, further shaping the spectrum of light transmitted to the imaging sensor which also has spectrally varying sensitivity. Parameters of the scintillator construction, the optics, and the imaging sensor are chosen so the output of the composite detector is proportional to a characteristic of the input beam, for example the dose deposited as a function of depth inside the tissue phantom.

摘要： Embodiments generally describe systems, devices, and methods for focusing and calibrating beam profilers. A test object is provided that may include an internal housing rotatable within an external housing. The internal housing may house a light source, a collimator, a filter, and/or a diffuser. A plate may be mounted to the internal housing and may include a plurality of markings. In some embodiments, to focus a beam profiler, the test object may be positioned adjacent the converter plate of a beam profiler. Marker images may be captured and a focus quality may be assessed therefrom. A position of the converter, objective, and/or camera of the beam profiler may be adjusted based on the focus quality. To calibrate, images of the markings in several rotational positions may be captured and used for calibration. The markings may be rotated to several positions by rotating the internal housing relative to the external housing.
