Abstract: Systems and methods are disclosed for performing operations comprising: receiving a plurality of training medical images used to train a machine learning technique; applying a model to the plurality of training medical images to generate a distribution representation of the plurality of training medical images; computing a first distance between a given training medical image in the plurality of training medical images and the distribution representation; computing a second distance between a new medical image and the distribution representation; and computing a quality factor indicating a measure of similarity between a new medical image and the plurality of medical images as a function of the first distance and the second distance.

Abstract: Devices, systems and techniques are used for cancer treatment. An example control device may be configured to be communicatively coupled to a radiation source of a radiotherapy device and a position sensor of the radiotherapy device. The example control device may be used to calculate, for a sliding window of a radiotherapy treatment, a positional error between: a measured target position signal determined from a series of images and sampled at the acquisition times of the images, and an estimated target position signal. The example control device may generate a computer-executable instruction configured to alter the radiotherapy treatment in response to the positional error violating a threshold.
