1. Name of the product in this design: Display screen for CT
scanner with a child-friendly
graphical user interface for operation and
data management. 2. Purpose of this design: For operation and control of the scanning procedure of a children's CT
scanner. 3. The key design features of this product are the
graphical user interface content on the product screen. 4. The image or photograph that best illustrates the design'
s key features: the front view. 5. Uses of
graphical user interface: for program operation,
data display, and
data management. 6. Description of the changing states of the graphical
user interface: Figure 1 shows the image page of the
system starting up and running normally; Figure 2 shows the image page of the patient being exposed during the scan; Figure 3 shows the image interface of the CT
scanner bed being unlocked; Figure 4 shows the graphical interface of the CT scanner in emergency stop mode. 7. Other situations requiring explanation: Other explanations: Description of the graphical
user interface, as follows: Interface area: The graphical
user interface is located in the entire display area of the screen. Human-computer
interaction method: The interface state is switched by hardware operation commands of the CT
machine (such as starting scanning, emergency stop triggering, etc.). Change process: Initial state: After the main view is completed and the
system starts up, the display screen automatically loads the main view 1 and synchronously presents the interface change
state diagram 1 (
system startup and normal operation page). The interface includes a
patient information display area, a
device status indicator area and an operation command entry area, which provides the basis for subsequent
state switching. Interface change
state diagram 1 → Interface change
state diagram 2 (
exposure scanning state) Triggering condition: Triggered by user through CT
machine hardware operation. Switching result: The interface is updated on the
layout frame of the main view 1, the
device status indicator area changes to "
Exposure Scanning" and displays the scanning
progress bar, the "Start Scan" button is locked, and the
patient information area remains unchanged. Interface change status diagram 2 → Interface change status diagram 3 (scanning
bed unlocked status) Trigger condition: After the CT
machine completes the
exposure scan, the hardware system automatically sends a "scan completed"
signal (no additional user operation required). Switching result: The
device status indicator area is updated to "Scan completed, scanning
bed unlocking" and displays an unlocking progress
animation. The "Scanning bed movement" operation buttons are unlocked, while the
patient information area continues to display the previous logic. Interface change state diagram 3 → Interface change state diagram 4 (emergency stop state) Trigger condition: During the stage of interface change state diagram 3 (unlocking), the user presses the red "
emergency stop button" on the CT machine body, and the hardware system sends an emergency
stop signal (highest priority trigger). Switching result: The interface immediately jumps to the warning-only page, retains the patient information, unlocks only the "Reset Emergency Stop" button, and locks all other functions.
