3-D planning

Nowadays, it is more common to practice 3 dimensional planning as it offers several advantages over 2 dimensional planning. Chief among these advantages is the ability to assess and correct for dose inhomogeneity arising from the varying contours of the breast.

3 Dimensional planning differs from 2 dimensional planning in several ways as well.

For a start, the simulation is performed virtually on a 3D model of the individual patient captured using a CT Scanner. The patient is positioned in the exact position as for treatment and this position is meticulously recorded to allow it to be reproduced during treatment.

The 3D model of the patient can be manipulated and used for planning is a total virtual environment so that the best plan can be created for each patient.

Just as in 2D planning. Tattoos is placed on the patient body to allow an accurate reproduction of the exact position for treatment later.

3D plans ready for evaluation and patient treatment. 3 dimensional planning allows the use of advance techniques of treatment planning including conformal radiotherapy, intensity modulated radiotherapy and even external beam partial breast irradiation.
