The disclosure provides a quantum dot structure, a manufacturing method thereof, and a quantum dot light-emitting device. The quantum dot structure includes a core structure and a shell layer. The core structure includes a first metal element, at least one second metal element, and a non-metal element that bind through a chemical bond. The first metal element is a group III element, the non-metal element is a group V element, and the second metal element is a metal element different from the first metal element. In an inside-to-outside direction of the core structure, the content of the first metal element is in a descending order, the sum of content of the second metal element is in an ascending order, and the size of an optical band gap of the core structure is in the ascending order.

The present invention provides a scan gantry for a medical imaging system. The scan gantry comprises a bottom supporting frame and a tilt supporting frame that are connected to each other, wherein the tilt supporting frame is tiltable relative to the bottom supporting frame. The scan gantry further comprises a locking mechanism connected between the bottom supporting frame and the tilt supporting frame. In the process that the tilt supporting frame is being tilted relative to the bottom supporting frame, the locking mechanism is in an unlocked state; and when the tilt supporting frame is stationary relative to the bottom supporting frame, the locking mechanism is in a locked state to prevent the tilt supporting frame from moving relative to the bottom supporting frame.

The present invention provides an X-ray transceiving component for a CT imaging apparatus, comprising one or more bulb devices and a plurality of detector devices. The one or more bulb devices are configured to emit quadrate-tapered or fan-shaped X-ray beams. The plurality of detector devices are configure to receive the quadrate-tapered or fan-shaped X-ray beams emitted by the one or more bulb devices, each of the quadrate-tapered or fan-shaped X-ray beams comprising X-rays passing through a scanning field of view. Note that the plurality of detector devices are configured to receive X-rays passing through different areas within the scanning field of view, the one or more bulb devices are micro-focus bulb devices, and the plurality of detector devices are flat panel detectors or photoelectric coupling detectors. The present invention can greatly improve a resolution of CT imaging, increase imaging efficiency, and realize low-dose diagnosis in the case of ensuring that the scanning field of view is sufficient.

A cradle drive mechanism, a table and a patient imaging and carrying apparatus are provided. The cradle drive mechanism includes: a first portion, which is arranged on a main base and has a belt drive structure, wherein the belt drive structure is used to connect a cradle and drive the cradle to make a reciprocating motion; a second portion, which is arranged on a secondary base and has a secondary supporting and rotating member, wherein the second portion and the first portion form a gap therebetween, and the secondary supporting and rotating member is used to support the cradle; and two guiding and rotating members, which are arranged on the second portion and/or the first portion for guiding the cradle to move linearly. The present application can simplify the structure by adoption of the belt drive structure. Further, the gap between the second portion and the first portion does not attenuate the X-ray additionally, so the dose of the X-ray emitted can be decreased.

Cradle drive mechanism, a table, and a patient imaging and carrying apparatus

A CT collimator comprising a rotating slot part on a rotation shaft and having a plurality of blades, each blade has a slot of a different width and a radiation beam entering the collimator can only pass via a slot in one of the blades, each edge of each blade slot along a longitudinal direction has a convex curved surface structure, and in a vertical plane along a longitudinal direction, two side edges of the slot are curved, and each blade is arranged to be eccentric to the center of the rotation shaft. A CT system using the CT collimator, the detection area of the radiation rays projected to the radiation detector via the CT collimator can be maintained unchanged by adjusting the rotation angle of the blade, under the circumstance where the focus of the radiation source shifts during a CT scan.

CT collimator and CT system including the CT collimator

A self adjusting bearing for use on a CT gantry is provided. The self adjusting bearing is configured to be mounted on a main frame of the CT gantry and is configured to support a rotating base of the CT gantry wherein the self adjusting bearing includes a roller, a first component, and a second component, the roller is configured to support the rotating base and is rotatably mounted on the first component, the second component is configured to be mounted on the main frame, and the first component and the second component are configured to rotatably engage each other such that they can rotate relative to each other during the mounting of the self adjusting bearing.
