T/NAHIEM 49-2022 Stroke one-stop multi-modal imaging evaluation and operating room configuration requirements for rescue surgery

Scope

Scope: This standard specifies the composition and equipment configuration requirements of one-stop multimodal imaging assessment and treatment operating rooms for stroke. This standard applies to the construction of one-stop multimodal imaging assessment and treatment operating rooms for stroke. Main technical content: Using X-ray beams to scan a certain thickness of layers in the human body, the X-rays passing through these layers are received by detectors, converted into visible light, then converted into electrical signals by photoelectric conversion, and finally processed by a computer after being digitized by an analog/digital converter. Utilizing the principle of magnetic resonance, under the action of a strong magnetic field, an external radiofrequency excitation signal and a gradient magnetic field coding signal are applied to human tissues to form nuclear magnetic resonance. By collecting and reconstructing the nuclear magnetic resonance electromagnetic waves emitted by human tissues, structural or functional images of the human body can be drawn. A method of displaying brain blood vessels under X-ray. By applying specific processing to remove bones, muscles, and surrounding soft tissues, only pure vascular images are left, which are then displayed on a monitor. A dedicated room for intravenous thrombolysis in acute ischemic stroke, equipped with all the necessary equipment for intravenous thrombolysis.
