Monitoring organ morphology for radiation treatment delivery using ultrasound

A user device, comprising:

• a display;
• a memory;
• and
• a processor in communication with the display and the memory, the processor being configured to:
• receive ultrasound data acquired from a region-of-interest in a patient containing an anatomical target, wherein the ultrasound data were acquired using a plurality of ultrasound transducer arranged about the region-of-interest;
• access from the memory, reference ultrasound data acquired from the patient while the anatomical target was maintained at a specified reference morphology indicated by a radiation treatment plan;
• compare the ultrasound data with the reference ultrasound data, generating feedback data that indicate a conformance of the anatomical target morphology to the reference morphology;
• generate a user interface displayed to a user by the display;
• and
• present the feedback data in the user interface displayed by the display.

A method for monitoring agreement of an anatomical target morphology with a radiation treatment plan, the method comprising:

• (a) accessing ultrasound data with a computer system, wherein the ultrasound data have been acquired from a region-of-interest in a patient containing an anatomical target;
• (b) accessing reference ultrasound data with the computer system, wherein the reference ultrasound data have been acquired from the patient while the anatomical target was maintained at a specified reference morphology indicated by a radiation treatment plan;
• (c) generating feedback data with the computer system by comparing the ultrasound data with the reference ultrasound data, wherein the feedback data indicate an agreement of the anatomical target morphology to the reference morphology;
• and
• (d) outputting the feedback data to a user via the computer system.
