In various embodiments, a radiation therapy method can include loading a planning image of a target in a human. In addition, the position of the target can be monitored. A computation can be made of an occurrence of substantial alignment between the position of the target and the target of the planning image. Furthermore, after the computing, a beam of radiation is triggered to deliver a dosage to the target in a short period of time (e.g., less than a second).

Triggered treatment systems and methods

System and method for shaping the intensity profile of a radiation beam incident on a target volume. Embodiments according to the present disclosure include a multi-leaf collimator (MLC) capable of sharpening (e.g., 'trimming') a proton beam, the MLC having a reduced overall weight. Leaves of the MLC according to embodiments of the present disclosure have two regions of different density, where a high density region is proximal to a radiation beam so as to block a portion of the beam, and a lower density region provides structural integrity to the leaf while reducing overall MLC weight.

A dual pulse imaging method is provided comprising the steps of generating a first image of a region of interest by a first pulse delivering a first dose, generating a second image of the region of interest by a second pulse delivering a second dose different from the first dose, and computing a third image of the region of interest using data from the first and second images. A threshold can be identified for determining data from the first and second images to be used in computing the third image. A dual pulse imaging system is also provided.

A method for correction of scatter in an image includes receiving data of an image having a scatter characteristic, performing a deconvolution procedure on the data using Hermite expansion technique, and generating modified image data based on a result from the step of performing. A method for correction of scatter in an image includes receiving data of an image having a scatter characteristic, and generating modified image data using Fredholm integral technique.

Systems and methods for correction of scatter in images

An apparatus () for irradiating a target includes a radiation source () for generating a radiation beam and a multiple leaf beam adjuster () for collimating and adjusting the shape of the radiation beam from the radiation source () that would be projected on the target. An image detector () detects generates an image signal of the target. In response to the image signal, a control module () generate a beam adjustment signal for controlling the beam adjuster (), thereby enabling the radiation beam from the radiation source () to track the movement of the target.
