The Mindray DC-7 is a diagnostic ultrasound system designed for various medical imaging applications. It features a user-friendly interface with a touch screen and a multi-functional knob for intuitive operation. The system supports multiple imaging modes, including B-mode, Color Doppler Flow Imaging (CDFI), Power Doppler, Pulsed Wave (PW) Doppler, Continuous Wave (CW) Doppler, and optional 3D/4D imaging.
Function Description:
The DC-7 allows for comprehensive ultrasound examinations, from basic patient information entry to advanced image acquisition, measurement, and post-processing.
- Patient Management: Users can enter basic patient information via the touch screen or keyboard, select probes, and choose exam modes to initiate a new examination.
- Image Acquisition:
- B-Mode: Adjust parameters like iClear, Dynamic Range, IP, L/R Flip, iBeam, Noise Reject, Quad Mode, THI, Focus Number, Colorize, FOV, Frequency, Focus Position, Colorize Map, Gray Map, B Steer, Acoustic Power, Tissue Specific Imaging, Trapezoid, U/D Flip, Persistence, Smooth, Image Merge, Rotation, and Line Density using the touch screen and the B knob for gain adjustment.
- CDFI/Power Mode: Enter Color mode, adjust the Region of Interest (ROI) position and size using the trackball and Set button. Parameters include WF, Packet Size, Persistence, B/C Wide, Priority, Line Density, Dual Live, Flow State, Invert, Frequency, Scale, Baseline, Map, Steer, Color IP, B Display, Acoustic Power, Smooth, and Focus Position.
- PW/CW Mode: Enter PW mode, adjust the sample volume position, size, and angle using the trackball and dedicated knobs. Press [Update] or [PW] to obtain Pulse Wave Doppler.
- 3D/4D Imaging (Optional): Select a volume probe and exam mode, then use the touch screen to enter and adjust the ROI and curve VOI. Press [Start] or [Update] to enter real-time 4D imaging.
- Measurement: After freezing an image, the system allows for various application-specific measurements. Users can select measurement tools via the touch screen or cursor and apply them to desired positions.
- Post-Processing:
- Comments and Body Marks: Add comments to images and place body marks to indicate probe orientation.
- Image and Cine Saving: Save single-frame images or cine loops to the system using dedicated save buttons.
- Reporting: Generate reports by typing text into comment boxes and adding selected images. Reports can be previewed and printed.
- Image Management (iStation): The iStation feature allows users to manage images, including transferring them to USB devices or DICOM networks. Images can also be selected for transfer via the Review function.
- End Exam: Conclude an examination, preparing the system for a new patient.
Usage Features:
The DC-7 is designed for ease of use with several key features:
- Touch Screen Interface: Provides direct access to parameters and functions, enhancing workflow efficiency.
- Multi-functional Knob: A central control for adjusting various parameters, including probe orientation for body marks.
- Trackball: Used for navigating menus, positioning ROIs, and adjusting sample volumes.
- Dedicated Buttons: Clearly labeled buttons for common functions such as Patient, Probe, Review, Report, End Exam, Body Mark, Cine, Arrow, Clear, Comment, iStation, Measure, Update, Save1, Save2, Zoom, iTouch, Depth, and Freeze.
- Image Adjustment Areas: The display is organized into mode displaying areas, parameter adjusting areas, and knob adjusting areas, providing a clear overview of active settings and adjustable parameters.
- Quick Reference Guide: A physical guide is provided for quick access to essential operating instructions.
