Specifications
The theory of HY2900 High Intensity Focused Ultrasound (HIFU) is to
focus the ultrasound energy in patients issues and form a high intensity
focusing area inside. The temperature of focused area will increase over
70 within 0.5 to 1 second to curdle and putrefy the cells in the
focusing area.
The main feature of the system: It adopts tri-dimension curative
ultrasound transducer with excellent focusing character and small
focusing area. It can ensure the patient to be contacted closely with
the machine owing to ultrasound imaging, mechanical electronic scanning
& positioning, high precision eight-direction curative machine and
multi-direction patient bed. It uses the technology of computer aided
melting discrimination for medical operation. The doctor can conclude
the curing circuitry by the computer upon the tri-dimension image and
judge the curative effect through melting discrimination technology.
--Main performance and technique indexes--
(1) Operate the corresponding button on the control desk can order the
ultrasound focus treating head to move up, down, swing in vertical or
lateral level in a certain range.
(2) Operate the scanning move system can order the focusing ultrasound
transducer to rotate in a range of 0o180o and move up, down, left,
right, forward and backward in a range of 0mm~100mm in the direction of
X, Y, Z.
The probe should move up and down independently and the information of
the corresponding position can be reflected.
(3) Pulse control: the pulse duration time (Ton) is between 0.1ms and
600s and can be regulated by integral number multiple of 0.1s; the pulse
off time (Toff) is no less than 0.1ms; the pulse number can be regulated
in a range of 0~30,000.
(4) Insulation resistance:
a) the insulation resistance between the high potential and the low
potential of the focusing ultrasound transducer: ≥10MW
b) the insulation resistance between the high potential of the focusing
ultrasound transducer and the metal shell: ≥10MW
(5) The oxygen dissolved capacity of excluding oxygen in the water:
≤5mg/L
(6) Ultrasound power supply:
a) working frequency: 1.5MHz±10%
b) frequency range: ≥1.5MHz±10%
c) Sound and Light Alarming: alarm at overcurrent
(7) system noise( except the water processing system): ≤65dB(A)
(8) Focusing transducer
a) focus length: 135mm160mm
b) range of focused area: <1.5mm×1.5mm×9mm
c) the largest acoustic intensity of the focused area: ≥5000W/cm2 when
output is at the peak.
(9) Distinguishing rate of the ultrasound diagnostic system:
Lateral distinguishing rate: ≤2mmdepth≤80mm
≤4mm80 vertical distinguishing rate: ≤1mmdepth≤80mm
≤2mm80(10) Input powerno less than 11kVA. |
