A medical device for tracking movement of a patient's body
A recently filed patent (Publication Number: US20230310893A1) describes a medical device designed to track the movement of a specific region of a patient's body. The device includes a controller with circuitry that can determine the motion of the region based on initial images, predict when certain properties or the position of the region will meet specific criteria, and determine when subsequent images should be captured.
The medical device also includes an imaging apparatus that is used to obtain the initial images. The controller can send instructions to the imaging apparatus to capture subsequent images at the determined times. Additionally, the controller can determine the location of the region in the initial images and use this information, along with the associated image capture times, to determine the motion of the region.
The properties associated with the motion or position of the region can include the direction or speed of motion. The device can predict when these properties will change by a threshold amount, allowing for more accurate tracking of the region's movement.
In the case of a radiotherapy device, the controller can update the treatment based on the determined motion or the location of the region in subsequent images. This can involve adjusting parameters that affect the delivery of radiation to the patient, such as gating the radiation beam, adjusting the shape or direction of the beam, or moving the patient supporting system.
The device can also generate a patient movement model based on the initial images and a surrogate signal indicative of movement of the patient's surface anatomy. This model allows for the estimation of the region's properties as a function of the surrogate signal and/or time. The controller can use this model to predict motion event times and update the model based on the difference between estimated and determined properties.
Overall, this patent describes a medical device that can accurately track the movement of a specific region of a patient's body, allowing for improved treatment and monitoring in various medical applications.
