Device Story
HDI 1500/SA 8800 is a mobile, software-controlled diagnostic ultrasound system. It acquires ultrasound data via various transducers (Linear, Convex, Phased Array, Static) and displays B-mode, M-mode, Color-Flow, CW/PW Doppler, and Power Doppler. The MPT7-4 transesophageal transducer uses a multi-element array on a gastroscopic articulating device to generate steered/focused beams for cardiac and non-cardiac imaging. System features digital beamforming and digital dynamic receive focusing. Operators use a control panel to adjust transmit focusing, filtering, and image enhancement. The system performs measurements (distances, areas, volumes) and provides analysis packages for obstetrics, cardiac, and vascular studies. Biopsy guidance is supported via optional adapters. Output is displayed on a monitor; remote viewing is supported via DICOM 3.0. Clinicians use the system for real-time diagnostic imaging and procedure monitoring to assist in clinical decision-making and tissue sampling.
Clinical Evidence
Bench testing only. The device relies on established ultrasound technology and compliance with electromechanical safety standards (EN 60601-1, UL 2601-1, IEC 1157). No clinical trial data was required for this clearance.
Technological Characteristics
Mobile ultrasound system using digital beamforming and digital dynamic receive focusing. Transducers use piezoelectric materials for ultrasound transmission/reception. Supports frequencies 2.0-12.0 MHz. Connectivity via DICOM 3.0. Safety standards: EN 60601-1, UL 2601-1, C22.2 No. 601.1, IEC 1157, EN 60601-1-2. Acoustic output: 720 mW/cm2 ISPTA, 1.9 MI.
Indications for Use
Indicated for diagnostic ultrasound imaging or fluid flow analysis in adult, pediatric, and neonatal patients for abdominal, obstetrical, cerebrovascular, peripheral vascular, gynecological, fertility, small parts, intraoperative, musculoskeletal, transcranial, prostate, and cardiac applications, including transesophageal imaging.
Regulatory Classification
Identification

#### 3) Identification of the predicate or legally marketed device:
ATL believes that the MPT 7-4 scanhead to be used with the HDI 1500/SA 8800 Ultrasound system is substantially equivalent to the currently marketed MPT7-4 transducer marketed with the ATL HDI 5000 System, K961459, and the Olympus Ultrasonic Endoscope (K963023).
#### 4) Device Description:
The HDI 1500/SA 8800 system is a general purpose, mobile, software controlled, diagnostic ultrasound system. Its function is to acquire ultrasound data and to display the data as B-mode, M-mode, Color-Flow Doppler, Continuous (CW) Doppler, Pulsed (PW) Doppler and Power Doppler, or as a combination of these modes. The HDI 1500/SA 8800 also gives the operator the ability to measure anatomical structures and offers analysis packages that provide information that is used to make a diagnosis by competent health care professionals. The HDI 1500/SA 8800 has real time acoustic output display with two basic indices, a mechanical index and a thermal index, which are both automatically displayed.
{1}------------------------------------------------
Eleven different models of transducers are available and any three may be connected at the same time. In addition to the initial operational settings for each transducer preprogrammed in the system, user-customized parameter settings for each transducer may be inserted by the operator and stored for recall as needed via the system control panel. Customization includes transmit focusing, filtering, image enhancement processing, dynamic window curve selection. Controls are also provided to select display format (single and various combinations), to activate zoom features, and to utilize the cine loop function.
The HDI® 1500/SA 8800 system uses digital beamforming technology, and supports a variety of Linear, Convex, Phased Array and Static probes for a wide variety of applications. It is an ultrasound scanner, which provides high resolution, high penetration performance, and various measurement functions. Probes are supported in frequencies from 2.0 MHz to 12.0 MHz. These probes can be applied to a variety of clinical applications such as abdominal, obstetrical, cerebrovascular, peripheral vascular, gynecological and fertility, small parts, intraoperative, vascular, abdominal surgery, conventional musculoskeletal, transcranial Doppler, pediatric general imaging, prostate, adult cardiology, pediatric cardiology and transesophageal (cardiac and non-cardiac). The same clinical uses were cleared for the predicate devices, ATL's 5000 (K961459) and the Olympus GF Type UM30P Ultrasonic Endoscope (K963023.)
The system can be used to measure distances and calculate areas, circumferences and volumes, as well as calculate the date of delivery by using BPD (biparietal diameter), OFD (occipito-frontal diameter), HC (head circumference), AC (abdominal circumference), AD (abdominal diameter), FL (femur length), CRL (crown rump length), APTD (anteroposterior trunk diameter), TTD (transverse trunk diameter), GS (gestational sac), LMP (last menstural period.), Cardiac Analysis and Vascular Analysis.
The MPT7-4 transducer is a multi-element ultrasound transducer mounted on a gastroscopic articulating device. The transducer elements are electronically time- and phase-coordinated to generate a steered and focused ultrasound beam, which produces a high-resolution real-time image. The transducer allows a circular continuum of tomographic images within a 185-degree arc without moving the transducer.
The MPT7-4 has a transducer array that rotates along an axis perpendicular to the axis of the probe shaft. At 0-degree orientation, the acquired tomographic plane is equivalent to the transverse plane, and at approximately 90-degree orientation, sagittal plane images can be obtained with the transducer array about 30 cm from the patient's teeth. The transducer array can be rotated up to 180 degrees, which provides a mirror image of the 0-degree orientation. Multiple tomographic image planes are continuously selected by rotating the transducer array without significant manipulation of the MPT7-4 transducer.
The MPT7-4 transducer is used for cardiac and non-cardiac transesophageal 2D and M-mode imaging, pulsed-wave and continuous-wave Doppler, and Color Doppler imaging.
Biopsy guidelines are provided on screen to assist in the collection of tissue samples, using biopsy guide adapters offered as an optional accessory. The Biopsy guides are the same as those previously cleared for the predicate device, ATL's HDI 5000 system (K961459). The operating Modes of HDI 1500/SA 8800 system are B-Mode, M, Color-Flow Doppler, Continuous wave (CW) Doppler, Pulsed (PW) Doppler, Power Doppler, or as a combination of these modes. Mmode uses the sweep display method, which has its images flow from the left to the right on the monitor. The HDI 1500/SA 8800 system supports the Cine function (capable of storing up to 64 sequential images) and real-time zoom function to the region-of-interest. The system provides the ability to perform remote viewing of images, without compression, via a Dicom 3.0 compatible output. Management of patient history is possible by image-filing function. High-resolution images are provided by utilizing a technology called digital dynamic receive focusing.
