Abstract: An example apparatus includes bias control circuitry and sampling circuitry. The example sampling circuitry includes a first switch coupled to a first capacitor in series between an input voltage terminal and a common mode voltage terminal, the first switch including a first terminal coupled to the input voltage terminal. Additionally, the example sampling circuitry includes a second switch coupled to a second capacitor in series between the input voltage terminal and the common mode voltage terminal, the second switch including a first terminal coupled to the input voltage terminal. The example sampling circuitry also includes a third switch including a first terminal, a second terminal, and a control terminal, the first terminal of the third switch coupled to a power supply terminal, the second terminal of the third switch coupled between the first switch and the first capacitor, the control terminal coupled to the bias control circuitry.

Abstract: Embodiments of the present invention describes a risk indicator device for a CT-examination comprising a data interface configured to receive a dataset of a patient, the dataset comprising patient demographic data, data about previous treatments and data about medication of the patient; a risk indicator unit configured to evaluate a risk-probability for the CT-examination based on the patient demographic data, the data about the previous treatments and the data about the medication of the patient; and an output unit configured to output at least one of output information or control data based on the evaluated risk-probability. Embodiments of the present invention further describe a respective method, a related risk prediction model, a patient scheduler and a CT-system.
