Medical imaging systems, devices, and methods

1. An imaging system comprising:

a scanner comprising:

a cart coupled to a rail, wherein (a) the cart is configured to move along the rail in a first direction, and (b) the rail is configured to move with the cart in a second direction transverse to the first direction;

an imaging device including one or more cameras coupled to the cart, the imaging device being configured to rotate about an axis extending in the second direction and to capture image data of an anatomical region of a subject;

one or more light sources;

one or more sensors configured to detect a position of the cart on the rail;

a first motor configured to move the one or more cameras along the rail in the first direction, and

a second motor configured to move the cart with the one or more cameras in the second direction; and

a computer system operatively coupled to the scanner, the computer system being configured to:

control the first motor and the second motor;

rotate the one or more cameras about a second axis extending in the second direction while the one or more cameras are moving in the first direction;

receive the image data from the scanner; and

construct a three-dimensional image of the anatomical region based on the image data.

2. A method of operating a scanner including one or more light sources and one or more cameras configured to capture a three-dimensional image of a subject, the method comprising:

activating the one or more light sources by selectively activating one or more white lights and one or more yellow lights of the scanner based on a skin tone of the subject;

activating the one or more cameras, wherein the one or more cameras are coupled to a cart movably coupled to a rail;

moving the cart along the rail in a first direction; and

moving the cart along the rail in a second direction different from the first direction.

3. The imaging system of claim 1 , wherein the one or more light sources include one or more white lights and one or more yellow lights.

4. The imaging system of claim 1 , wherein the rail is curved in an arc.

5. The imaging system of claim 1 , wherein the imaging device includes multiple cameras with different focal points.

6. The method of claim 2 , further comprising rotating the one or more cameras about an axis extending in the second direction.

7. The method of claim 2 , wherein activating the one or more light sources further includes adjusting an intensity of the one or more white lights and the one or more yellow lights.

8. The method of claim 2 , wherein the rail is curved in an arc and extends from a first end to a second end, and wherein moving the cart along the rail includes (a) moving the cart to the first end, and (b) moving the cart from the first end to the second end.

9. The method of claim 8 , wherein

moving the cart to the first end includes rotating the one or more cameras by an angle between about 5-30 degrees about the axis extending in the second direction as the cart moves towards the first end, and

moving the cart from the first end to the second end includes rotating the one or more cameras by an angle between about negative 5-30 degrees about the axis as the cart moves towards the second end.

10. The method of claim 8 , wherein moving the rail with the cart includes moving the rail in the second direction after (a) moving the cart to the first end, and before (b) moving the cart from the first end to the second end.

11. The method of claim 2 , wherein moving the cart and moving the rail with the cart together move the one or more cameras along a substantially rectangular path.

12. The imaging system of claim 1 , wherein the computer system is configured to control the first motor and the second motor to move the one or more cameras in a substantially rectangular path.

13. The imaging system of claim 1 , wherein the one or more light sources of the scanner includes one or more white lights and one or more yellow lights, and the computer system is further configured to selectively activate the one or more white lights and one or more yellow lights based on a skin tone of the subject by increasing a number of yellow lights activated as compared to the number of white lights activated for a darker skin tone, and increasing a number of white lights activated as compared to the number of yellow lights activated for a lighter skin tone.

14. The method of claim 2 , wherein:

moving the cart along the rail in the first direction includes moving the one or more cameras from an original location to a first end of the scanner, and

moving the cart along the rail in the second direction includes moving the one or more cameras in the second direction for a first time period while the one or more cameras are at the first end.

15. The method of claim 14 , further including:

moving the one or more cameras in a direction opposite the first direction to a second end of the scanner opposite the first end,

moving the one or more cameras in direction opposite the second direction for the first time period while the one or more cameras are at the second end, and

moving the one or more cameras in the first direction to the original location.

16. The method of claim 15 , further including:

rotating the one or more cameras about a first axis by an angle between about 5-30 degrees when the one or more cameras are moving from the original location to the first end, and

rotating the one or more cameras by about negative 5-30 degrees about the first axis when the one or more cameras are moving from the original location to the second end, wherein the first axis is an axis extending along the second direction.
