6 results about "Image-guided radiation therapy" patented technology

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.

This invention proposes a radiotherapy device, method, and storage medium. The radiotherapy device includes a treatment gantry, a treatment bed, radiotherapy components, and a scanning imaging system. The scanning imaging system includes a scanning ring and a moving mechanism. The scanning ring is configured to rotate around its own axis and is equipped with the scanning imaging components. The moving mechanism connects the scanning ring and the treatment gantry and drives the scanning ring to move between an image acquisition position and a standby position. In the image acquisition position, the image isocenter coincides with the treatment isocenter or has a preset fixed deviation; in the standby position, the scanning ring is entirely outside the irradiation path of the treatment beam. This invention achieves the movement of the scanning ring between the image acquisition position and the standby position through the moving mechanism, ensuring diagnostic-grade imaging quality while avoiding interference between the treatment beam and the imaging components. This significantly improves the accuracy and reliability of image-guided radiotherapy and enhances the flexibility of treatment.

Disclosed herein are systems and methods for guiding the delivery of therapeutic radiation using incomplete or partial images acquired during a treatment session. A partial image does not have enough information to determine the location of a target region due to, for example, poor or low contrast and / or low SNR. The radiation fluence calculation methods described herein do not require knowledge or calculation of the target location, and yet may help to provide real-time image guided radiation therapy using arbitrarily low SNR images.

The utility model discloses a three-dimensional adjusting support for an image-guided radiotherapy linear accelerator. The three-dimensional adjusting support comprises a clamp capable of stretching out and drawing back synchronously, a guide rod sliding block capable of driving the clamp to move and rotate, and an adjusting seat capable of adjusting the height of the guide rod sliding block. The guide rod sliding block comprises a smooth guide rod, a sliding block arranged on the smooth guide rod in a sleeving mode and an anti-friction sleeve arranged between the smooth guide rod and the sliding block. The fixedly-connected end of the smooth guide rod is fixedly connected with the clamp. The adjusting seat comprises a base and a lifting mechanism capable of lifting along the base, the top end of the lifting mechanism is fixedly connected with the sliding block, and the base is detachably connected with the treatment bed. The three-dimensional adjusting support can realize 360-degree rotation of the clamp and free adjustment of the horizontal transverse height and the vertical height, and the purpose of three-dimensional adjustment of the angle of the mobile phone is achieved.
