Disclosed herein is a radiological instrument () comprising at least one pulse shaper circuit () configured for a direct conversion radiation detector (). The at least one pulse shaper circuit comprises an amplifier (). The pulse shaper further comprises a feedback circuit () connected in parallel with the amplifier; a first switching unit () connected in series with the feedback circuit; a second switching unit () connected in parallel with the amplifier; a discriminator circuit () that provides a discriminator signal () when the output exceeds a controllable signal threshold; and a control unit () for controlling the first switching unit and the second switching unit, wherein the control unit controls the second switching unit such that a substantial part of the signal is integrated, when the second switching unit is closed.

Radiological instrument with a pulse shaper circuit

A method for converting spectral CT datasets into electron density datasets with applications in the fields of medical image formation or radiation treatment planning. The method comprises a preparation method that fits free parameters of a generalized electron density prediction model based on obtained electron density values such as data on tissue substitutes, and a conversion method using the fitted parameter prediction model and spectrally decomposed CT data as first and second inputs, respectively. The method is particularly useful in dual-energy CT and more specifically in dual layer detector CT systems.

Creation of electron density datasets from spectral CT datasets

Embodiments of the present invention provide a processor having an inactive state of operation and methods thereof. The processor, according to some demonstrative embodiments of the invention, the processor may include a controller to determine an inactive state of operation is to be entered, and to cause a predetermined set of one or more execution units to execute a predetermined sequence of one or more micro-operations prior to entering the inactive state. Other embodiments are described and claimed.
