Abstract

Systems, instruments, and methods for medical treatment are disclosed. The methods comprise, by a computing device: receiving information identifying at least one first point on a body part shown in a medical image; overlaying a first mark on the medical image for the at least one first point; generating a spline based at least on the first mark; overlaying a second mark for the spline on the medical image; identifying a location of at least one second point on the body part shown in the medical image based on the first and second marks; overlaying a third mark for the at least one second point on the medical image; and using at least the third mark to facilitate the medical treatment of an individual whose body part is shown in the medical image.

First claim

What is claimed is:

1. A method for medical treatment, comprising:
receiving, by a computing device, information identifying at least one first point on a body part shown in a medical image;
overlaying, by the computing device, a first mark on the medical image for the at least one first point;
generating, by the computing device, a spline based at least on the first mark;
overlaying, by the computing device, a second mark for the spline on the medical image;
identifying, by the computing device, a location of at least one second point on the body part shown in the medical image based on the first and second marks;
overlaying, by the computing device, a third mark for the at least one second point on the medical image;
analyzing differences in gray levels for pixels residing within a given area surrounding an end of the third mark to determine a precise location of an object corner; and
modifying at least one of a shape of the third mark, a size of the third mark and a location of the third mark relative to the medical image in accordance with results of the analyzing; and
using at least the third mark to facilitate the medical treatment of an individual whose body part is shown in the medical image.

2. The method according to claim 1 , further comprising performing operations, by the computing device, to cause an imaging device to capture the medical image.

3. The method according to claim 1 , wherein at least one machine learned model is additionally used to generate the spline.

4. The method according to claim 3 , wherein the at least one machine learned model defines a possible structure of a spine.

5. The method according to claim 1 , wherein the spline comprises a piecewise polynomial curve.

6. The method according to claim 1 , wherein the second mark comprises a curved line that (i) extends between a mid-point of the first mark and a mid-point of another mark, and (ii) extends along a centerline of the body part.

7. The method according to claim 1 , wherein the first and second points comprise vertebrae endpoints.

8. The method according to claim 1 , wherein the location of the at least one second point is identified further based on at least one of a machine learned model and contents of a scientific database.

9. The method according to claim 1 , wherein the precise location of the object corner is determined by:
defining a circle within the medical image that encompasses an end point of the third mark; and
considering the given area as comprising an area of the medical image contained in the circle.

10. A system, comprising:
a processor;
a non-transitory computer-readable storage medium comprising programming instructions that are configured to cause the processor to implement a method for medical treatment, wherein the programming instructions comprise instructions to:
receive information identifying at least one first point on a body part shown in a medical image;
overlay a first mark on the medical image for the at least one first point;
generate a spline based at least on the first mark;
overlay a second mark for the spline on the medical image;
identify a location of at least one second point on the body part shown in the medical image based on the first and second marks;
overlay a third mark for the at least one second point on the medical image;
analyze differences in gray levels for pixels residing within a given area surrounding an end of the third mark to determine a precise location of an object corner; and
modify at least one of a shape of the third mark, a size of the third mark and a location of the third mark relative to the medical image in accordance with results of the analyzing; and
use at least the third mark to facilitate the medical treatment of an individual whose body part is shown in the medical image.

11. The system according to claim 10 , wherein the programming instructions further comprise instructions to cause an imaging device to capture the medical image.

12. The system according to claim 10 , wherein at least one machine learned model is additionally used to generate the spline.

13. The system according to claim 12 , wherein the at least one machine learned model defines a possible structure of a spine.

14. The system according to claim 10 , wherein the spline comprises a piecewise polynomial curve.

15. The system according to claim 10 , wherein the second mark comprises a curved line that (i) extends between a mid-point of the first mark and a mid-point of another mark, and (ii) extends along a centerline of the body part.

16. The system according to claim 10 , wherein the first and second points comprise vertebrae endpoints.

17. The system according to claim 10 , wherein the location of the at least one second point is identified further based on at least one of a machine learned model and contents of a scientific database.

18. The system according to claim 10 , wherein the precise location of an object corner is determined by:
defining a circle within the medical image that encompasses an end point of the third mark; and
considering the given area as comprising an area of the medical image contained in the circle.
