SIEMENS and ACUSON Sequoia 512 Ultrasound Device and Probes Analysis Report

Device Identification

The examined visuals belong to an advanced ultrasonography system mounted on a wheeled stand, intended for stationary use in medical imaging. The device consists of a main processing unit, an integrated monitor, a user control panel, and various ultrasound probes (transducers).

Brand and Model Information

As a result of a detailed examination of the visuals, the brand and model information of the device and its components have been identified as follows:

• Main Device Brand/Model: The phrase ACUSON Sequoia 512 is clearly visible on the front panel of the device’s main body and on the processing unit.
• Monitor Brand: The SIEMENS logo is located on the upper frame of the CRT monitor at the top of the device.
• Probe (Transducer) 1 Brand/Model: In the close-up visual (of the linear type), the ACUSON brand and 8L5 model code are clearly seen on the probe.
• Probe (Transducer) 2 Brand/Model: In the other close-up visual (of the convex type), the ACUSON brand and 6C2 model code are located on the probe.

Originality and Production Quality

The print quality of the logos on the product, the general material structure of the device (plastic injection quality), the regular arrangement of the keypads, and the compatible socket structure of the ACUSON brand probes with the device indicate that the product is an original medical device. There is no visual evidence suggesting it is a sub-industry or replica product.

Areas of Use

This device is designed for use in medical diagnosis and imaging. Considering the probes identified in the visuals:

• General Device: Used for imaging internal organs, vascular structures, and soft tissues in specialties such as Radiology, Cardiology, and Obstetrics & Gynecology.
• ACUSON 8L5 Probe: Typically a linear probe suitable for vascular, thyroid, breast, or superficial tissue imaging.
• ACUSON 6C2 Probe: Typically a convex probe used for abdominal, obstetric (pregnancy), and gynecological imaging.

Quantity Information

In total, the visuals show:

• 1 unit of ACUSON Sequoia 512 Ultrasound Main Console and Monitor,
• 1 unit of ACUSON 8L5 Ultrasound Probe,
• 1 unit of ACUSON 6C2 Ultrasound Probe.

Note: The cable connections visible in the probe slots on the device confirm that the two examined probes are connected to the device.

General Condition and State

The device is in a used condition. It should be evaluated in the category of second-hand medical devices. Although its physical integrity appears to be preserved, there are natural signs of wear due to use from an aesthetic perspective. The general structure of the device appears solid, not presenting a fragmented or disassembled appearance.

Physical Deformation and Wear Analysis

• Color Change: There is a noticeable yellowing (oxidation) in the light-colored plastic parts of the device’s main body and around the keyboard, which is believed to be due to age and exposure to sunlight. This indicates that the device may have an old manufacturing date.
• Surface: Wear due to long-term use can be observed on the control panel and palm rest areas, but no deep scratches or cracks have been detected.
• Monitor: There are no significant cracks or fractures on the monitor casing.

Mechanical and Electronic Component Analysis

• Monitor Type: The device features an older CRT (cathode ray tube) type monitor instead of current LCD/LED technology. This indicates that the device’s model year is old.
• Control Panel: The QWERTY full keyboard, trackball, TGC (Time Gain Compensation) sliders, rotary knobs, and function keys are physically in place. No missing keys are observed.
• Disk Drive: An old type MO (Magneto-Optical) disk drive or a similar media slot, likely used for image recording, is visible on the front face of the main unit.
• Foot Pedal: An integrated foot pedal mechanism, likely used for image freeze or print functions, is present at the bottom of the device.
• Cable Condition: No severe damage such as crushing, breakage, or outer sheath peeling has been visually detected on the probe cables. The cable colors also show slight yellowing similar to the main body.

Battery and Power

Since the device is a large hospital-type “cart-based” system, it operates with mains electricity (AC power). No external battery cell or portable battery status is visible in the visuals, but it cannot be externally determined whether there is an internal UPS or battery system within the device for power outages.

Label and Code Information

Codes readable from the visuals are listed below:

• Main Unit: ACUSON Sequoia 512
• Monitor: SIEMENS
• Linear Probe Model: 8L5
• Linear Probe Brand: acuson (Lowercase logo type)
• Convex Probe Model: 6C2
• Convex Probe Brand: acuson (Lowercase logo type)

Screen Analysis

The device is in the off position at the time the visuals were taken. The monitor screen is black, therefore, software version, operating system, error messages, or operating hours information could not be analyzed. No deep scratches or cracks are visible on the screen surface.

Potential Risks and Important Notes

Based on the visual analysis, the following points should be noted by the buyer:

• Technology Age: The CRT monitor and media drive slot on the device indicate that the system is an older generation ultrasound device. Spare part availability and current technical service support should be separately investigated by the buyer.
• Probe Membranes: The visuals do not include detailed macro shots of the rubber membranes (lens part) on the probe tips. The most critical part for ultrasound image quality is the probe tips; although any potential bulging or perforation here cannot be detected from the visuals, it should be checked due to the age of the device.
• Plastic Fatigue: Yellowing in the device casing can cause the plastic material to harden and become more brittle. Care should be taken during transportation.

Conclusion

The examined product is a Siemens / Acuson Sequoia 512 Ultrasonography System with a medical history, including its probes (6C2 and 8L5), showing cosmetic wear (yellowing) due to its age but maintaining its integrity. No physically missing parts (keys, covers, etc.) are visible.
