Abstract: The disclosure is directed to an automated disinfection system for a CT patient table, where the automated disinfection system for a CT patient table includes: a disinfection mechanism disposed above the CT patient table; a detection mechanism, disposed on the disinfection mechanism and configured to detect a position of the CT patient table; and a control mechanism, configured to communicate with the disinfection mechanism by using a communication interface, so as to control start/stop and operation of the disinfection mechanism, where the disinfection mechanism is configured to perform horizontal movement and vertical movement during scanning gaps of a plurality of patients, so as to disinfect a use surface of the CT patient table. The disclosure enables rapid and automated disinfection on the use surface of the CT patient table during scanning gaps of a plurality of patients, thereby reducing a risk of cross-infection and saving manpower.

Abstract: A target position determination of a single-slot collimating plate and a collimator assembly are disclosed. A first measurement signal is acquired based upon of the first instance of air scanning, when the single-slot collimating plate moves a predetermined distance from a starting position to a first position in a first direction of the Z axis. A second measurement signal is acquired based upon the second instance of air scanning, when the single-slot collimating plate moves a predetermined distance from the starting position to a second position in the direction opposite to the first direction. A composite measurement signal and a composite air calibration signal are determined based upon the first measurement signal and the second measurement signal. The composite measurement signal is calibrated using the composite air calibration signal. The target position of the single-slot collimating plate is determined based upon the calibrated composite measurement signal.

Abstract: A medical bed horizontal driving mechanism includes a bracket, a drum, an electric motor, and a position sensor. The bracket is configured to be fixedly connected to a bed frame of a medical bed. The drum is rotatably connected to the bracket. The drum is rotatable to drive a bed board of the medical bed to move relative to the bed frame. The electric motor is arranged in a cavity of the drum. A housing of the electric motor is fixedly connected to the bracket. An output shaft of the electric motor is connected to the drum to drive the drum to rotate relative to the bracket. The position sensor is arranged in the cavity of the drum. The position sensor can detect a rotational position of the drum and generate a position signal, which is used to control the electric motor.

Abstract: An X-ray collimator has a collimation plate, and a shielding box made of a tungsten plastic composite, the shielding box having an opening on the top and the bottom thereof respectively, and a support part for supporting the shielding box. The collimation plate is disposed on the shielding box or the support part. Compared to the use of the shielding box alone, the collimator reduces the volume of the collimator without reducing its shielding performance.

Abstract: A computer system for image processing has a first working environment with a first program for image processing, as well as a second working environment, logically separated from the first working environment, with a second program for image processing. The first working environment is implemented on a first server. Furthermore, the first working environment is designed to receive a first command to execute the first program and a second command to execute the second program, and to send the second command to the second working environment. The second working environment is designed to send an image processed by the second program to the first working environment . The communication of a user with the first and second program thus occurs via a uniform platform in the form of the first working environment, and the integration of the second program for image processing into the workflow is facilitated.
