Abstract: A system and method for a hybrid detector for a computed tomography (CT) system are provided that include a semiconductor detector arranged to generate photon-counting CT data upon receiving x-rays and a scintillator detector arranged proximate to the semiconductor detector to receive scattered x-rays and generate energy-integrating CT data upon receiving the scattered x-rays.

Abstract: A system and method for generating a computed tomography (CT) image of an object includes establishing a narrow-spectrum high-energy bin and other bins with wider-spectrum and lower-energies and acquiring a first dataset using the narrow-spectrum high-energy bin. The method also includes acquiring second or more datasets using the wide-spectrum, low-energy bins, reducing data attributable to scatter from the second or more datasets using the first dataset to create reduced-scatter datasets, and reconstructing CT images of the object from the reduced-scatter datasets.

Abstract: An electrostatic discharge (ESD) avoiding circuit comprises an ESD detecting unit and a switch unit. The ESD detecting unit is coupled to a first conductive path for detecting whether the ESD happened or not. The switch unit is coupled between the first conductive path and a core circuit for switching whether the first conductive path is conducted to the core circuit or not according to a detection result of the ESD detecting unit. The ESD avoiding circuit can avoid an electrostatic current transmitting to the core circuit when the ESD is happened, and the ESD avoiding circuit can make the normal signal/voltage providing to the core circuit for operating when the ESD isn't happened.
