Abstract
Embodiments are directed to a new imaging modality called X-ray-induced acoustic computed tomography (XACT) technology and can be combined with traditional pulse and echo ultrasound imaging. It has the capability of real-time monitoring of geometric and morphological misalignments of the X-ray field with respect to the target tissue, thus improving radiotherapy tumor eradication and limiting treatment side effects. The XACT/US image-guided radiotherapy system according to embodiments holds great potential for personalized cancer treatment and better outcomes.
Claims20
A system for X-ray-induced acoustic computed tomography (XACT) comprising:
- a radiation module configured to apply a dose of radiation to a target in a living subject and to induce an acoustic signal associated with the dose of radiation;
- an ultrasound module configured to generate an ultrasound image of tissue surrounding the target in the living subject;
- and
- an imaging module configured to combine the ultrasound image with an image representing the dose of radiation with respect to the surrounding tissue.
A method of X-ray-induced acoustic computed tomography (XACT) comprising:
- applying, by a radiation module, a dose of radiation to a target in a living subject and to induce an acoustic signal associated with the dose of radiation;
- generating, by an ultrasound module, an ultrasound image of tissue surrounding the target in the living subject;
- and
- combining the ultrasound image with an image representing the dose of radiation with respect to the surrounding tissue.
