A lucency just means a dark area on the x-ray/CT as opposed to an opacity (which is a white area). I'm not sure what type of CT scan you got (i.e. with or without contrast injection), but don't jump to conclusions about it being cancer..... lucency just means a dark area on the x-ray/CT as opposed to an opacity (which is a white area).

The operational details of amplifiers are buried in the field of electronics, but for audio purposes it is usually safe to say that current commercial audio amplifiers are so good that a normally operating amplifier is seldom the limitation on the fidelity of a sound reproduction system.
PA500L â PA1000L Linear Amplifiers â Low Noise and Distortion Performance. Compact standalone amplifiers designed to support LDS vibration test systems, use both permanent magnet shakers and also small electrodynamic shakers. Both are used with a separate field power supply. The PA500L and PA1000L amplifiers are linear amplifiers with very low noise and distortion performance. Features.
