Axial computed tomography slices of a patient revealing the presence of four fiducial markers.
Anterior–posterior and lateral paired kV images of a patient on treatment day 1.
Seroma size and AiMD for all the patients on day of CT simulation. The seroma size was defined as the cubic root of seroma volume. Clear correlation can be observed with a value of 0.78.
Change in average intermarker distance (AiMD) after simulation for all 34 patients. The markers represent the measurement data. A line is an exponential fit to the data for one patient.
Percent change of seroma size over a course of treatment (from the CT simulation to completion of treatment).
Percent of patients with a 20% and 10% change in seroma size (%) after simulation as a function of postsurgery days of CT simulation.
The correlation coefficents between seroma volume and various intermarker distance parameters, and between the cubic root of seroma volume and various intermarker distance parameters.
The change of ratio of seroma volume and cube of AiMD with time. The volume and AiMD are normalized to the values of the corresponding initial CT scan.
The AiMD and related fitting information for all the patients. SOT stands for start of treamtent and EOT for end of treatment.
