An augmentation tag associated with a location in one layer of the acquired medical image can be retrieved. A further operation can be projecting the acquired medical image and the augmentation tag using an augmented reality headset to form a single graphical view as an overlay to the patient anatomy in either 2D, 3D or holographic form.

Introduced here are pressure-mitigation apparatuses able to mitigate the pressure applied to a human body by the surface of an object. A controller device can be fluidically coupled to a pressure-mitigation device that includes a series of selectively inflatable chambers. When a pressure-mitigation device is placed between a human body and a surface, the controller device can continuously, intelligently, and autonomously circulate air through the chambers of the pressure-mitigation device. As further discussed below, the controller device may cause the chambers to be selectively inflated, deflated, or any combination thereof. Such an approach is useful in a variety of contexts. For example, pressure-mitigation apparatuses may be used to improve treatment of patients suffering from respiratory illnesses and patients who are partially or completely immobilized for extended durations (e.g., as part of a medical procedure).
