TLD DOSIMETRY INSERT 
MODEL 038-06
Features:
• Provides 2D or 3D dose verification
• Receives TLD chips, rods, bars cubes   
and disks
• Ø5 mm through holes in a 1cm x 1cm  
grid pattern
MULTIPLE OSL DOSIMETRY TARGET INSERT 
MODEL 038-08
Features:
• Drilled for nanoDot™ OSL spaced 4.1 mm  
apart in two orthognal directions 
• Allows 3D measurements by rotating
• Measurements in embedded soft-tissue  
target and penumbra 
• Easy insertion and removal of nanoDot™ 
OSL Dosimeters with no air gaps
The TLD Dosimetry Insert allows 2D and 
3D dose verification using TLDs. The insert 
consists of a brain-equivalent cube drilled in 
a 1 cm X 1cm grid pattern of 5mm diameter 
through holes. Each hole is filled with a 5mm 
diameter brain-equivalent solid plug for use 
for TLDs placement . TLD can be positioned 
between plugs at the desired depth within 
each hole. Tissue-equivalent plugs cast to 
precisely receive TLD chips, rods, bars and 
cubes are avialable separately. 
The Multiple-OSL Dosimetry Target Insert 
enables 2D point-to-point dosimetry in two 
orthogonal directions both inside the target 
and penumbra using Landauer nanoDots™. 
By rotating the insert in 3 orthogonal direc
tions, it also enables 3D dosimetry. 
Model 038-08 consists of a brain-equivalent 
cubic insert with a 30 mm diameter spherical 
target with +5% contrast.  The insert receives 
27 OSL dosimeters through the center plane 
of the sphere.  Cube is assembled using four 
pinholes with an off-set arrangement that al
lows for consistent assembly. External marks 
machined outside both halves make it easy to 
align when assembled.

MODEL 038-21
The Film Stack Insert is a brain-equivalent 
cube for use in small-volume dose map
ping with film. The Film Stack can be used 
for treatment plan verfication of targets in 
different shapes and sizes, including multi
metastasis targets. The Film Stack accommo

The brain-equivalent cubic insert includes a 
30 mm diameter spherical target with +5% 
contrast. It receives a single piece of radio
chromic film through the center plane of the 
sphere. A pin-point ion chamber cavity is ma
chined into half of the target sphere allowing 
simultaneous measurements of absolute dose 
& dose distribution inside the target. Film can 
be positioned inside the 5mm deep pocket 
which contains 6 stainless steel fiducials assy
metrically placed. Fiducials provide a means 
for easy treatment plan registration
