Systems and methods for radiographic monitoring of shunts

A system for monitoring a shunting element implanted in a patient and having a lumen fluidly coupling a first body region of the patient and a second body region of the patient, the system comprising:

• a processor;
• and
• a memory storing instructions that, when executed by the processor, cause the system to perform operations comprising:
• receiving first radiographic image data of at least two radiopaque elements associated with the lumen, wherein a spatial relationship between the at least two radiopaque elements varies according to a size of the lumen, wherein the lumen of the shunting element is selectively adjustable to control fluid flow therethrough, and wherein the first radiographic image data is taken from a first viewing angle;
• receiving second radiographic image data of the at least two radiopaque elements, wherein the second radiographic image data is taken from a second viewing angle different than the first viewing angle;
• and
• determining the size of the lumen based, at least in part, on locations of the at least two radiopaque elements in the first and second radiographic image data.

A non-transitory computer-readable medium storing instructions that, when executed by a processor of a system for monitoring a shunting element implanted in a patient and having a lumen fluidly coupling a first body region of the patient and a second body region of the patient, cause the system to perform operations comprising:

• receiving first radiographic image data of at least two radiopaque elements associated with the lumen, wherein a spatial relationship between the at least two radiopaque elements varies according to a size of the lumen, wherein the lumen of the shunting element is selectively adjustable to control fluid flow therethrough, and wherein the first radiographic image data is taken from a first viewing angle;
• receiving second radiographic image data of the at least two radiopaque elements, wherein the second radiographic image data is taken from a second viewing angle different than the first viewing angle;
• and
• determining the size of the lumen based, at least in part, on locations of the at least two radiopaque elements in the first and second radiographic image data.
