|
USER INPUT:
|
|
|
|
Tissue
|
Layer 1 (Max 10 cm)
|
Select Tissue TYPE from pull-down
menu: muscle, fat, blood etc
|
Layer1 is the most prevailing
superficial tissue layer,e.g. muscle
|
|
|
Layer 2 (Max 5 cm)
|
Enter tissue thickness in cm, with 1
decimal, e.g.:
|
2,5
|
cm.
|
Layer2 is the more profound tissue
e.g. bone.
|
|
|
Distance
(d) from skin to lesion =
|
|
How far beyond the skin surface is
the lesion?
|
Use palpation, and anatomical
knowledge. MR-scan og Ultrasound scan, are very helpfull when available.
|
|
|
Therapeutic
Intensity, I(d)=
|
|
Enter the intensity desired in the
lesion, the therapeutic intensity
|
|
|
frequency=
|
|
Enter the frequency of the
ultrasound, e.g. 1 MHz
|
Usually available from 0,75 MHz to 3
MHz in physiotherapy devices. Any option can be entered.
|
|
|
Show
Reflexion:
|
|
Turn the display of reflexion ON/OFF
by a click
|
Reflexion bouncing off the
interface between layer 1 and 2 and back from the exterior surface, shown
graphically.
|
|
|
Pulse-ratio=
|
|
|
Displays the decimal
value og the pulse-ratio
|
1,0= 100%= continuous
|
TRUE
|
1:9= 10% time on, = 0,1 etc.
|
|
|
Select
Pulse-regime from menu:
|
|
Select Pulse regime by clicking
a "radio-button"
|
|
|
Local
TreatmentTime, lt=
|
|
The therapeutic exposure time for a
cell in the lesion
|
|
|
Transduzer
|
size(ERA)=
|
|
The cross-section of the ultrasound
beam. Often called the ERA (Effective Radiation Area). Read on the apparatus/
Transducer.
|
|
|
Lesion
area (A)=
|
|
The size of the lesion= The target
tissue area, that is supposed to be exposed to ultrasound.
|
|
|
To
obtain the Target values select
|
|
|
Apparatus
INTENSITY setting
|
|
|
|
NOT
adjusted for reflexion=
|
|
Tweak or dial in this INTENSITY
SETTING on your Ultrasound Device to obtain the desired dosage in the lesion.
|
|
|
RISK:
|
|
When the Apparatus Intensity is
below 2W/cm², you'll see RISK:
"OK", - otherwise RISK: HIGH INTENSITY
|
|
|
And
Apparatus TIMER setting =
|
|
Tweak or dial in this TIMER SETTING
on your Ultrasound Device to obtain the desired local exposure time in the
lesion.
|
|
|
RESULTS
|
(including reflexions)
|
|
Where the reflected wave interferes
with the primary wave, the intensity can build up to this value.
|
|
|
|
|
And You may wish to COMPENSATE for
REFLEXION, by turning down the THERAPEUTIC INTENSITY, maybe som 30%. Gradual
adjustment can provide more precise results.
|
|
Highest
Intensity=
|
|
The highest intensity including
reflexion ocurring at the skin surface.
|
|
|
Generated
heat at d=
|
|
The heat generated in the lesion.
|
|
|
|
|
The highest value of heat generation
(including reflexion) found in layer #1
|
|
|
|
|
|
The highest value of heat generation
(including reflexion) found in layer #2
|
|
|
RESULTS
|
(WITHOUT reflexions)
|
|
|
|
|
|
|
Generated
heat at d=
|
|
Heat generated at the lesion without
regard to reflexion
|
|
|
|
|
The highest value of heat generation
(excluding reflexion) found in layer #1
|
|
|
|
|
|
The highest value of heat generation
(excluding reflexion) found in layer #2
