Chapter 1 Overview
1.1Function Introduction
The digital portable ultrasound diagnostic system DP-3300/3200
is intended to use for the
following studies:
fetal organs, abdomen, pediatrics, small parts, neonatal cephalic,
transvaginal, transrectal, peripheral vascular, superficial and conventional musculoskeletal
,
etc.
The Digital Ultrasonic Diagnostic System
DP-3300/3200
is intended to use for the
examinations such as
abdomen,
gynecology, obstetrics, small parts, and orthopedics
. The
DP-3300 system has the measurement and calculation functions of abdomen,
gynecology, obstetrics, and orthopedics
, and the DP-3200 system has the measurement
and calculation functions of abdomen and
obstetrics
.
1.2Introduction of Complete Machine
The DP-3300/3200 system is a digital portable ultrasound diagnostic system, which is
compact and cost-effective. The DP-3300/3200 system can work with three types of
transducers（big convex array, linear array and intra-cavity）, and can be used for
examinations of abdomen, gynecology, obstetrics, urology, pediatrics, small parts and
intra-cavity. This system adopts the imaging technologies such as digital beamforming,
continuous dynamic focusing, odd-even line discrepancy elimination, and multiple-focus
splicing. It has the functions of monitor output, performance testing report, and video
printing.
1.2.1Basic features
1. Supports the convex and linear array transducers
2. Supports the real-time adjustment of imaging parameters, so that the optimal images
can be acquired;
3. Transducer frequency: 2MHZ to 12MHZ;
