The present disclosure provides a method and apparatus for image guidance, a medical device and a computer-readable storage medium. The method for image guidance includes: controlling an imaging mechanism to rotate around a patient positioning mechanism; acquiring a first image in response to that the imaging mechanism is rotated to any one of the capturing angles, the first image being a medical image of the patient captured by the imaging mechanism at a first capturing angle, and the first capturing angle being a capturing angle to which the imaging mechanism is currently rotated; performing, after a second image corresponding to the first image is acquired, image guidance using a combination of the first image and the second image as an indicator of a current position state of the patient.

Devices, systems, and methods for planning radiosurgical treatments for neuromodulating a portion of the renovascular system may be used to plan radiosurgical neuromodulation treatments for conditions or disease associated with elevated central sympathetic drive. The renal nerves may be located and targeted at the level of the ganglion and/or at postganglionic positions, as well as preganglionic positions. Target regions include the renal plexus, celiac ganglion, the superior mesenteric ganglion, the aorticorenal ganglion and the aortic plexus. Planning of radiosurgical treatments will optionally employ a graphical representation of a blood/tissue interface adjacent these targets.

A positioning method realized by a computer including acquiring a gamma angle for treatment; acquiring first coordinates of a treatment couch, the first coordinates being coordinates of the treatment couch when a preset shooting point coincides with an imaging point of an image guidance system (IGS); determining a first relative position between a target point of an affected part and the imaging point according to the gamma angle for treatment; acquiring a second relative position between the imaging point and an equipment isocenter; calculating second coordinates of the treatment couch at the gamma angle for treatment when the target point coincides with the equipment isocenter according to the first coordinates, the first relative position and the second relative position; and adjusting a position of the treatment couch according to the second coordinates.

A medical apparatus includes an acquirer, an associator, and a display controller. The acquirer acquires information indicating a respiratory waveform of an object and acquires fluoroscopic images of the object captured in time series. The associator associates a tracking value which fluctuates according to a respiratory phase of the object, based on the time-series fluoroscopic images. The display controller causes a display to display the respiratory waveform and a waveform of the tracking value in a comparable form.

Techniques for adjusting radiotherapy treatment for a patient in real-time are provided. The techniques include determining a patient anatomy at a first time within a given radiotherapy treatment fraction after a radiotherapy treatment dose has been delivered by a radiotherapy device; retrieving a reference patient anatomy for the given radiotherapy treatment fraction that indicates a prescribed dose parameter to be delivered within the given radiotherapy treatment fraction; comparing the patient anatomy at the first time with the reference patient anatomy during the given radiotherapy treatment fraction; and based on the comparison of the patient anatomy at the first time with the reference patient anatomy, adjusting a parameter of the radiotherapy device to change an amount of radiotherapy treatment dose delivered at a second time, following the first time, within the given radiotherapy treatment fraction in accordance with the prescribed dose parameter to be delivered within the given radiotherapy treatment fraction.

Disclosed is a computer-implemented method for determining the position of an anatomical tracking structure in a tracking image usable for controlling radiation treatment such as at least one of radiotherapy or radio surgery of a patient, a corresponding computer program, a non-transitory program storage medium storing such a program and a computer for executing the program, as well as a system for the position of an anatomical tracking structure in a tracking image usable for controlling radiation treatment such as at least one of radiotherapy or radio surgery of a patient, the system comprising an electronic data storage device and the aforementioned computer.

Systems and methods for automatic, customized radiation treatment plan generation for cancer are disclosed. According to an aspect, a method includes receiving data indicating anatomy information of a patient and radiation beam characteristics of a radiation therapy system. Further, the method includes determining energy levels for application of radiation beams to the patient.

An object positioning apparatus comprising: a radiographic image input interface configured to acquire a radiographic image that is generated by causing a fluoroscopic imaging apparatus to image an object and includes a first region and a second region, the first region depicting an index region for positioning of the object, the second region depicting a non-index region other than the index region; and a positioning processor configured to perform the positioning of the object by performing matching processing between a previously generated reference image and the first region that is specified from the radiographic image based on three-dimensional model information of the non-index region.
