HERA Z20 knobology

Dr. Eunjoo Dong — Wed, 04 Feb 2026 08:45:18 +0000

Key Highlights

Learn practical ultrasound knobology on HERA Z20, including hands-on setting optimization for gain, TGC, depth, focal zone, frequency, and obstetric imaging.

This hands-on demo presented by Prof. Conrado Coutinho focuses on ultrasound knobology and practical optimization of machine settings using the HERA Z20 platform.

Rather than a theoretical lecture, the session demonstrates real-time adjustments of core ultrasound controls to improve obstetric image quality. Key parameters such as overall gain, time gain compensation (TGC), depth, focal zone placement, and frequency selection are shown in practice, illustrating how each control directly influences image clarity, contrast, and penetration.

The demo highlights common pitfalls in machine setup, including excessive gain, improper focal positioning, and incorrect depth configuration. Through live examples, Prof. Coutinho shows how systematic knob adjustments can restore anatomical definition and enhance visualization of fetal structures.

Emphasis is placed on understanding the relationship between resolution and penetration, and on adapting settings according to gestational age and patient characteristics. The session reinforces that optimal image quality depends not only on advanced technology but also on operator awareness and structured setting refinement.

Overall, this ultrasound knobology demo provides practical, step-by-step guidance for clinicians seeking to improve HERA Z20 performance and achieve consistent image optimization in daily obstetric practice.

Demonstration of detecting nerves

Thu, 29 Aug 2024 06:26:13 +0000

This short demonstration video showcases the use of NerveTrack, an AI-assisted ultrasound feature designed to automatically identify and highlight nerves during scanning. The video focuses on two key anatomical targets: the median nerve and the ulnar nerve.

In the first part of the demonstration, the transducer is positioned to visualize the median nerve in the forearm. The system’s interface displays a real-time ultrasound image with a highlighted bounding box over the nerve, enabling clear and consistent localization. This assists clinicians in quickly identifying the nerve for diagnostic assessments or ultrasound-guided interventions such as nerve blocks.

In the second segment, the probe is moved to locate the ulnar nerve. Again, NerveTrack automatically detects the nerve and marks it on-screen, minimizing manual adjustments and reducing the risk of misidentification. The system’s real-time tracking ensures that even slight probe movements do not interrupt nerve visualization.

This technology is particularly useful in regional anesthesia, pain management, and musculoskeletal applications, where precision in nerve identification is critical for patient safety and procedural success.

Animal Scan with HM70 EVO

Thu, 29 Aug 2024 06:22:48 +0000

This demonstration video showcases the versatility of the HM70 EVO, a high-performance hand-carried ultrasound system designed for diverse clinical settings, including veterinary ultrasound. Led by Dr. Iwayoshi Isamu, the session features ultrasound examinations on various dogs, demonstrating the system’s advanced imaging capabilities across multiple anatomical regions.

The HM70 EVO provides high-resolution imaging that supports accurate diagnostics for a wide range of animal ultrasound applications. During the demonstration, Dr. Isamu performs detailed scans on different dogs, highlighting the system’s flexibility and effectiveness in dog ultrasound procedures.

Abdominal areas assessed include:

Subxiphoid view: Liver left lobe, hepatic vein, and portal vein.
Left adrenal gland: Imaging of glandular structures.
Pancreas (right lobe) and pancreaticoduodenal vein: Detailed visualization of pancreatic anatomy.
Jejunum (transverse and longitudinal views): Examination of intestinal loops and wall structures.
Right common iliac vein (CVC): Assessment of pelvic vascular structures.
Urinary bladder and ureteral openings: Imaging bladder function and ureter entries.
Liver (caudate lobe), abdominal aorta, CVC, and portal vein: Comprehensive abdominal evaluation.
Stomach and pylorus: Visualization of gastric anatomy.

Cardiac ultrasound views include:

Right parasternal long axis 4-chamber view
Right parasternal short axis views: Papillary muscle level, Aortic level, Artery level
Left apical view

The HM70 EVO enhances veterinary ultrasound procedures with its portable design, durability, and streamlined workflow. Its superior imaging quality and intuitive operation support efficient and accurate diagnostics in both dog ultrasound and broader animal ultrasound contexts.
