Described here are systems and methods for determining the spatial location of a radiation source, such as a radiation source moving in a brachytherapy applicator (e.g., an afterloader catheter, a needle) during a brachytherapy procedure. Conductive elements coupled to the brachytherapy applicator are operable as radiation detectors that can measure spatiotemporal signal data to localize the position of the radiation source as it moves within the brachytherapy applicator. The conductive elements may include micro-structured wires (e.g., coaxial micro-structured wires), micro-structured conductive strips, conductive thin films, or other patterns of conductors. Other detector types may include ion chambers, solid-state detectors, or resistive electrodes.

Disclosed herein is a method comprising: sending radiation pulses (i), i=1, . . . , M one by one toward an object and toward an image sensor as the image sensor moves nonstop in a first direction with respect to the object; and for each value of i, capturing with the image sensor a partial image (i) of the object using radiation of the radiation pulse (i) that has transmitted through the object. The image sensor comprises N active areas. Each active area of the N active areas comprises multiple sensing elements. For each value of i, the radiation pulse (i) has a pulse duration during which the image sensor travels a distance shorter than a width measured in the first direction of any sensing element of the image sensor. M and N are integers greater than 1.
