Abstract: A power control circuit comprises a signal input, a controllable attenuator, an amplifier, an output, a power detector, a reference circuit, a comparator, an external control input, an error detector, and a controller. The comparator, error detector, and controller are digital circuits realized by a microprocessor. The attenuator is between the signal input and the input to the amplifier to regulate the amplifier's output. The power detector couples to the amplifier output to generate a measurement signal representing the power at the output. The reference circuit generates a reference signal representing a predetermined minimum output when the signal input is nonzero. The comparator compares the measurement and reference signals and generates a decision signal indicating if the signal input is nonzero. The external control input receives an external control signal. The error detector is coupled to the power detector and the external control input and computes the difference between the external control signal and the measurement signal. When the measurement signal is at or above the minimum power, the controller provides an integral of the computed difference to control the variable attenuator. When the measurement signal is below the minimum power, the controller keeps the attenuator at a prior constant value.

Abstract: A radiation quantum-counting method and apparatus for producing high resolution radiographic images capable of discriminating soft tissue cancer having a lcm size. The high resolution image is generated by a plurality of radiation sensitive elements, each element including a semiconductor material having a pair of electrodes mounted on opposite faces thereof. Each element is highly sensitive and produces a rapid pulse count since the thickness of the semiconductor material is substantially 0.1-0.5 mm, and the semiconductor material has an effective atomic number greater than 30 and an energy band gap greater than 1.3 eV. As a plurality of radiation quanta emanate from the radiation source, they are received by the plurality of radiation sensitive elements which detect individual radiation quantum and produce a pulse signal for each detected quantum. Coupled to each radiation sensitive element is a pulse amplifier for amplifying the pulse signals. The amplified pulse signals are counted and used to produce radiographic image signals containing details of image gradation. The pulse count may also be stored in a memory and used to provide two-dimensional information when combined with other pulse count data derived when the spatial orientation between the objective body and the radiation source is changed.
