Abstract: Systems and methods for the image-based determination of the fluid status of a patient are described. In one example, an apparatus may include at least one processor and a memory coupled to the at least one processor. The memory may include instructions that, when executed by the at least one processor, may cause the at least one processor to receive an image that may include at least one image of a portion of a patient, determine fluid status information for the patient by processing the image via a trained computational model, the trained computational model trained based on at least one training image of the patient and a corresponding physical measurement of fluid status, the fluid status information indicating a current fluid status of the patient, and determine a treatment recommendation for the patient based on the fluid status information. Other embodiments are described.
