Methods and systems for the concurrent generation of multiple substantially similar X-ray beams

An adjustable collimator device adapted to collimate a beam of X-rays emitted from a radiation source, comprising:

• an elongated body with a front-end and a rear-end;
• a first plurality of emission apertures equally spaced around a longitudinal axis extending through a center of the elongated body, wherein the longitudinal axis defines a zero-degree position, wherein the first plurality of emission apertures is placed proximate the rear-end of the elongated body, and wherein the first plurality of emission apertures is configured to receive the beam of X-rays entering the adjustable collimator device;
• and
• a second plurality of emission apertures placed proximate the front-end of the elongated body, wherein the second plurality of apertures are adjustable such that a first of the second plurality of apertures can be configured to have a first angular offset relative to the zero-axis and a second of the second plurality of apertures can be configured to have a second angular offset relative to the zero-axis, and wherein each of the second plurality of apertures is formed by two jaws having lengths which extend in the same direction as the beam of X-rays such that the beam of X-rays is collimated to yield a first beam of X-rays and a second beam of X-rays, separate from the first beam of X-rays but with substantially similar characteristics, that are concurrently emitted from the adjustable collimator device.
