Systems, method and devices for detecting, analyzing and treating lesions, such as skin cancer are disclosed. Such a system can include a high-frequency ultrasound imaging device to image a lesion. The system can also include a processor that executes instructions stored in memory to perform operations, and the operations can include receiving a plurality of images of the lesion from the high-frequency ultrasound imaging device, rendering a three dimensional model of the lesion using the plurality of images from the high-frequency ultrasound imaging device and determining a treatment dosimetry based on the three dimensional model of the lesion. The system can also include a radiotherapy device to provide radiotherapy treatment to the lesion, where the radiotherapy treatment is based on the treatment dosimetry.
