Seed Implant Dosimetry
Treatment Planning
PSID 4.5 ( NEW ) -
Upgrades available – Permanent Seed Implant Dosimetry – An innovative software
for Prostate Brachytherapy with pre-, interactive online and
post planning.
Interactive Online Planning
PSID supports interactive real time planning for transversal and
longitudinal ultrasound imaging with precise matching of planned
seed positions in relation to actual seed locations. Dose
distributions, histograms and their figures of merits e.g. V100,
D90 for the prostate or D1 for the urethra, are immediately
updated to provide the physician with the most current
information. Seed positions are optimised automatically with
respect to dose limits for the rectum and urethra.
Automatic Seed Detection
For post planning, PSID provides a state of the art search
algorithm that identifies seed positions quickly and precisely –
without the need to specify the number of seeds. This results in
a substantial reduction in planning time by removing the need to
verify every seed position.
Multiple Report Functions
An extensive and customisable report function provides physician
defined information and streamlined output.
User Friendly
The PSID user interface features a modern and easy-to-use
structure, including customisable tool bars to meet the users’
treatment planning style.
Complete and Comprehensive
The BEBIG version of PSID provides pre-planning from ultrasound
images to interactive online planning during surgery followed by
post planning of the implant with precise and easy to use
comprehensive software.
