Abstract
There is described a computer-implemented method for designing a stent, comprising: providing for display a first image of a 3D model of at least a portion of a body part comprising an aneurysm; receiving a position for each one of a plurality of reference points chosen along the body part; inserting in the first image a visual marker at the position of each reference point, thereby obtaining a second image; providing the second image for display; for each reference point, calculating a respective diameter; calculating at least one length using the positions of the reference points; and outputting the respective diameter and at least one length.

A computer-implemented method for designing a stent, the computer-implemented method comprising:
- providing for display a first image of a 3D model of a body part of a subject, the body part comprising at least an infrarenal segment of a thoracic aorta, an aneurysm on the infrarenal segment of the thoracic aorta, an aortic bifurcation and at least a portion of a left common iliac artery and a right common iliac artery;
- receiving a position for each one of a plurality of reference points, the reference points comprising at least an inflection point of the suprarenal segment, a bottom of a neck of the aneurysm, a bottom of the aneurysm, a first point and a second point on the left common iliac artery and a first and a second point on the right common iliac artery;
- inserting in the first image a visual marker at the position for each reference point, thereby obtaining a second image;
- providing the second image for display;
- for each reference point, calculating a respective diameter;
- calculating a first length of the neck using the position of the inflection point of the suprarenal segment and the position of the bottom of a neck of the aneurysm, a second length of a left landing area using the position of the first point and second points on the left common iliac artery, a third length of a right landing area using the position of the first point and second points on the right common iliac artery, a fourth length of a left leg of the stent and a fifth length of a right leg of the stent using the position of some of the reference points;
- calculating a suprarenal neck angle using the position of the inflection point of the suprarenal segment and the position of the bottom of the neck of the aneurysm, and an infrarenal neck angle using the position of the bottom of the neck of the aneurysm and the position of the bottom of the aneurysm;
- and
- outputting the respective diameter for each reference point, the first, second, third, fourth and fifth lengths, the suprarenal neck angle and the infrarenal neck angle.

- a processor;
- and
- a non-transitory computer readable storage medium comprising instructions stored thereon;
- the processor, upon execution of the instructions, being configured for:
- providing for display a first image of a 3D model of a body part of a subject, the body part comprising at least an infrarenal segment of a thoracic aorta, an aneurysm on the infrarenal segment of the thoracic aorta, an aortic bifurcation and at least a portion of a left common iliac artery and a right common iliac artery;
- receiving a position for each one of a plurality of reference points, the reference points comprising at least an inflection point of the suprarenal segment, a bottom of a neck of the aneurysm, a bottom of the aneurysm, a first point and a second point on the left common iliac artery and a first and a second point on the right common iliac artery;
- inserting in the first image a visual marker at the position for each reference point, thereby obtaining a second image;
- providing the second image for display;
- for each reference point, calculating a respective diameter;
- calculating a first length of the neck using the position of the inflection point of the suprarenal segment and the position of the bottom of a neck of the aneurysm, a second length of a left landing area using the position of the first point and second points on the left common iliac artery, a third length of a right landing area using the position of the first point and second points on the right common iliac artery, a fourth length of a left leg of the stent and a fifth length of a right leg of the stent using the position of some of the reference points;
- calculating a suprarenal neck angle using the position of the inflection point of the suprarenal segment and the position of the bottom of the neck of the aneurysm, and an infrarenal neck angle using the position of the bottom of the neck of the aneurysm and the position of the bottom of the aneurysm;
- and
- outputting the respective diameter for each reference point, the first, second, third, fourth and fifth lengths, the suprarenal neck angle and the infrarenal neck angle.
