Active bleeding measurement

A method for operating a computing system including at least one processor to determine a treatment for a human patient identified as having a pelvic injury, the method comprising:

• receiving, by the at least one processor, CT images, wherein the CT images were generated by performing a CT angiography of an abdomen and a pelvis of the human patient;
• detecting, by the at least one processor based on the CT images, a trigger feature in the CT images, and automatically, in response to the detection of the trigger feature, determining by the at least one processor, based on the CT images, a total volumetric rate of active abdominopelvic bleeding to an accuracy of at least 0.1 cc/min, comprising:
• determining by the at least one processor, based on the CT images, a first local volumetric rate of active bleeding at a first site in the injured body region to an accuracy of at least 0.1 cc/min, wherein the determination is made by:
• determining a first volume of extravasation at the first site during a first imaging phase;
• determining a second volume of extravasation at the first site during a second imaging phase;
• and
• determining the first local volumetric rate of active bleeding at the first site based upon the first volume of extravasation and the second volume of extravasation at the first site and an amount of time between the first and second imaging phases at the first site;
• determining by the at least one processor, based on the CT images, a second local volumetric rate of active bleeding at a second site in the injured body region to an accuracy of at least 0.1 cc/min, wherein the determination is made by:
• determining a third volume of extravasation at the second site during a first imaging phase;
• determining a fourth volume of extravasation at the second site during a second imaging phase;
• and
• determining the second local volumetric rate of active bleeding at the second site based upon the third volume of extravasation and the fourth volume of extravasation at the second site and an amount of time between the first and second imaging phases at the second site;
• and
• determining by the at least one processor, based on the first local volumetric rate and the second volumetric rate, the total volumetric rate of active bleeding;
• and
• recommending, by the at least one processor, at least one treatment approach for the human patient based on the total volumetric rate of active abdominopelvic bleeding.

One or more non-transitory computer-readable media having embodied thereon computer-executable instructions that, when executed by a processor, cause the processor to determine a treatment for a human patient identified as having an injury to a body region by:

• receiving CT images, wherein the CT images were generated by performing a CT angiography of an injured body region of the human patient;
• identifying a trigger event based on the CT images, the trigger event comprising detecting a trigger feature in the CT images;
