Vivid Pioneer is a general-purpose ultrasound system, specialized for use in cardiac imaging. It is intended for use by, or under the direction of a qualified and trained physician or sonographer for ultrasound imaging, measurement, display and analysis of the human body and fluid.
Vivid Pioneer is intended for use in a hospital environment including echo lab, other hospital settings, operating room, Cath lab and EP lab or in private medical offices. The systems support the following clinical applications:
Fetal/Obstetrics, Abdominal (including renal, GYN), Pediatric, Small Organ (breast, testes, thyroid), Neonatal Cephalic, Adult Cephalic, Cardiac (adult and pediatric), Peripheral Vascular, Musculo-skeletal Conventional, Musculo-skeletal Superficial, Urology (including prostate), Transesophageal, Transvaginal, Transrectal, Intra-cardiac, Intra-luminal and Interventional Guidance (including Biopsy, Vascular Access), Thoracic/Pleural and Intraoperative (vascular).
Modes of operation include: 3D, Real time (RT) 3D Mode (4D), B, M, PW Doppler, CW Doppler, Color Doppler, Color M Doppler, Power Doppler, Harmonic Imaging, Coded Pulse and Combined modes: B/M, B/Color M, B/PWD or CWD, B/Color/PWD or CWD, B/Power/PWD.
The proposed Vivid Pioneer is a general purpose, Track 3, diagnostic ultrasound system, which is primarily intended for cardiac imaging and analysis but also includes vascular and general radiology applications. It provides digital acquisition, processing, display and analysis capabilities. It consists of a mobile console with a height-adjustable control panel, color LCD touch panel, and a display monitor.
Vivid Pioneer includes a variety of electronic array transducers operating in linear, curved, sector/phased array, matrix array or dual array format, including dedicated CW transducers and real time 3D transducer. The proposed Vivid Pioneer can be used with the stated compatible OEM ICE transducers. The system includes capability to output data to other devices like printing devices.
The user-interface includes an operator control panel, a 23.8" High-Definition Ultrasound LCD type of display monitor (mounted on an arm for rotation and / or adjustment of height), a layout of pre-defined user controls (hard-keys) and a 15.6-inch multi-touch LCD panel with mode-and operation dependent soft-keys.
The operator panel also includes two loudspeakers for audio, shelves for convenient placement of papers or accessories, and 6 holders with cable management for the connected transducers.
The lower console is mounted on 4 rotational wheels with brakes, for ergonomic transport and safe parking. The lower console also includes all electronics for transmit and receive of ultrasound data, ultrasound signal processing, software computing, hardware for image storage, hard copy printing, and network access to the facility through both LAN and wireless (supported by use of a wireless LAN USB-adapter) connection.
This document describes the acceptance criteria and study proving the device meets the criteria for two AI features of the Vivid Pioneer Ultrasound System: AI Cardiac Auto Doppler and AI FlexiViews LAA.
1. Table of Acceptance Criteria and Reported Device Performance
AI Cardiac Auto Doppler
| Acceptance Criteria | Reported Device Performance |
|---|---|
| Feasibility score of > 95% | All clinical parameters, as performed by AI Cardiac Auto Doppler without user edits, passed the check for mean percent absolute error across all cardiac cycles against a threshold. This implies the accuracy threshold was met, which indirectly suggests successful feasibility to achieve this accuracy. |
| Expected accuracy threshold calculated as the mean absolute difference in percentage for each measured parameter. | All clinical parameters, as performed by AI Cardiac Auto Doppler without user edits, passed this check. |
| Mean percent absolute error across all cardiac cycles against a threshold. | All clinical parameters, as performed by AI Cardiac Auto Doppler without user edits, passed this check. |
| Consistent model performance across BMI groups ( |
§ 892.1550 Ultrasonic pulsed doppler imaging system.
(a)
Identification. An ultrasonic pulsed doppler imaging system is a device that combines the features of continuous wave doppler-effect technology with pulsed-echo effect technology and is intended to determine stationary body tissue characteristics, such as depth or location of tissue interfaces or dynamic tissue characteristics such as velocity of blood or tissue motion. This generic type of device may include signal analysis and display equipment, patient and equipment supports, component parts, and accessories.(b)
