Problems solved by technology

However, at least one difficulty that arises is that the LINAC could potentially collide or nearly collide with the patient's skin surface at an off-normal tilt of the curved rail with respect to the longitudinal axis.

Embodiment Construction

[0046] Systems, methods, and related computer program products for image-guided radiation therapy (IGRT) are described further below, including image-guided radiation therapy (IGRT) systems that provide an advantageous combination of: high mechanical stability, radiation Versatility during delivery, outdoor configuration, and the ability to keep the patient stationary between the time of (i) pre-treatment imaging and / or setup imaging and (ii) treatment delivery including in-treatment imaging. In a preferred embodiment, there is provided a radiotherapy apparatus comprising: an annular gantry having a central opening; a radiotherapy head connected to the annular gantry a frame and rotatable at least 180 degrees arc around the central opening; and a stage translation mechanism configured to translate the annular stage in a direction extending through the longitudinal axis of the central opening . In a preferred embodiment, the annular gantry is contained within an annular gantry...

Abstract

Systems, methods, and related computer program products for image-guided radiation treatment (IGRT) are described. For one preferred embodiment, an IGRT apparatus is provided comprising a ring gantry having a central opening and a radiation treatment head coupled to the ring gantry that is rotatable around the central opening in at least a 180 degree arc. For one preferred embodiment, the apparatus further comprises a gantry translation mechanism configured to translate the ring gantry in a direction of a longitudinal axis extending through the central opening. Noncoplanar radiation treatment delivery can thereby be achieved without requiring movement of the patient. For another preferred embodiment, an independently translatable 3D imaging device distinct from the ring gantry is provided for further achieving at least one of pre-treatment imaging and setup imaging of the target tissue volume without requiring movement of the patient.
