A patient interface system for scanning a volume of tissue protruding from a patient, the system comprising: a base including a planar portion configured to support the patient in a prone configuration, and a frustoconical portion extending from the planar portion and defining a base aperture configured to receive the volume of tissue; and a support assembly configured to couple to the base, including a frame and a membrane retained in tension within the frame at a peripheral portion of the membrane, wherein the membrane defines a membrane aperture configured to align with the base aperture, and wherein the membrane is configured to deflect into the frustoconical portion of the base in response to the patient's weight. The system can further include an electrical subsystem including a pressure sensor array configured to generate signals in response to a pressure distribution resulting from the patient's weight at the patient interface system..
