2 results about "Blood volume" patented technology

Systems and methods for receiving batches of sample containers (e.g., blood culture bottles), sorting the sample containers, and discarding negative sample containers in a safe, secure, and consistent manner are disclosed. Additionally, systems and methods to accurately and precisely determine the amount of sample inoculated into a container are disclosed. For example, an apparatus determines the amount of blood inoculated into a blood culture bottle by weighing and / or obtaining an image of the blood culture bottle inoculated with blood sample. Such an approach facilitates automation, as a user does not need to visually inspect each bottle.

The application relates to the technical field of medical image processing, and discloses a three-dimensional cerebral blood volume image generation method, system, device and medium. The method comprises the following steps: acquiring MRI three-dimensional body data and real CBV three-dimensional body data of a plurality of objects; gradually adding noise to each real CBV three-dimensional body data based on a diffusion model, and gradually denoising joint input formed by each noise-added sample and corresponding MRI three-dimensional body data; taking a denoising network of the diffusion model as a generator, acquiring all generated CBV three-dimensional body data output by the generator, discriminating each generated CBV three-dimensional body data according to a feature matching degree of the generated CBV three-dimensional body data and corresponding real CBV three-dimensional body data through a discriminator, and training the discriminator and the generator through a discrimination result of the discriminator and the feature matching degree; and inputting MRI three-dimensional body data of a target object into a model trained through the above steps, to generate a corresponding three-dimensional CBV image.
