Prostate Helical Tomotherapy: A semi-empirical estimation of the scaling factor based on 2D approximating field
Background: In Helical Tomotherapy (HT), the scaling factor (SF) is the time in seconds that each leaf viewing a target would need to be open to deliver the prescribed dose. The SF is patient-specific and is used to calculate the rotational period of the gantry, and the total treatment time (TTT) of the HT. The SF is generally difficult to estimate. Currently, it takes about one hour t...

15 صفحه اولSalvage helical tomotherapy for prostate cancer recurrence following definitive external beam radiotherapy: A case report.
Salvage prostatectomy for recurrent prostate cancer after external beam radiotherapy (EBRT) has resulted in positive outcomes; however, it is technically challenging and is associated with a number of risks. When a patient exhibits recurrent prostate cancer following definitive EBRT and presents with comorbidities meaning that they cannot receive a prostatectomy, it is difficult to treat due to...
