- Completely customisable
physician controlled power levels, with software recommendation
- Treatment based on tissue
response and proximity to vital structures such as
rectal wall and neurovascular bundles
|
- Limits physicians to
only 3 pre-set power settings
- Power settings are unchangeable
once treatment has begun, not allowing physicians to
adjust for changes in tissue density or tissue response
|
- Real-time neurovascular
bundle blood flow detection
- Real-time transverse and
sagittal images
- Real-time feedback of HIFU therapy
with Sonablate
Tissue Change Monitoring software (TCM). TCM quantifies
tissue changes based on a comparison of radio frequency
(RF) ultrasound pulse-echo signals at each treatment
site. TCM calculates the change and, with color
coding, displays it visually on-screen guiding
physicians
to the optimal delivery of HIFU energy
|
- No real-time sagittal
image
- No real-time tissue change response feature
|
- 10-12mm
- Greater precision for
critical spaces around the prostate, enabling user
to treat entire gland with 100% ablation and no spare
tissue
|
- 19-26mm
- Ablatherm users must leave tissue untreated near external sphincter and neurovascular
bundles, during nerve sparing procedures
- Protocol states
users must leave 4 mm “safety zone” untreated, potentially
leaving cancer cells and viable
PSA producing tissue behind
|
- Can treat up to a
40g prostate, without a transurethral resection of
the prostate (TURP)
|
- Can treat only up
to a 30g prostate
- Requires TURP for larger prostates
|
- Mobile
- Same footprint
of a conventional ultrasound machine
- Weighs 113
kg
|
- Not portable, footprint
of a surgical table plus an additional console
- Weighs
431 kg
|
- By using reference
and real time images the rectal wall is constantly
monitored to determine any changes to its structure
and changes to the treatment plan
- Active cooling system
circulates chilled water through the probe during
the procedure to ensure patient safety
|
- No monitoring of rectal
wall condition against changes cause by the treatment
or internal gland movement
- Relies on external motion
detection and refrigerated gel to keep temperatures
low
