AmCAD-US is a software device intended to visualize the statistical distributions of backscattered signals echoed by tissue compositions in the body. The backscattered signals are subject to the RF or Envelope data made available by an FDA-cleared general-purpose ultrasound system. The US-mode images displayed on AmCAD-US must not be used alone for primary diagnostic interpretation.
Device Description
AmCAD-US (model number 1.0) is intended to visualize and analyze the statistical distributions of backscattered signals echoed by tissue compositions in the body. AmCAD-US, which uses the proprietary technology and algorithms, is a software package designed to quantify and visualize the backscattered statistics contained in ultrasound image data obtained from an FDA-cleared general purpose ultrasound system. The device provides dual mode images, including conventional B-mode ultrasound image in gray scale and color-mapped US (ultrasound structure) mode image. The US-mode provides a means for viewing and displaying the backscatter statistical values. The device uses parametric model or nonparametric statistics that best describes the distribution curve of the backscattered signals. The parameters vary by the US method (backscattered statistics) selected. The preferences include options to set the parameters mapped onto the image and US method options applied to the data. The user can also select a specific region of interest (ROI) on the image for quantification analysis. The histogram view of the data provides a different view to accommodate the variation between tissue and tissue states. AmCAD-US has a data export function to record and save the analysis results. Note that the US-mode images displayed on AmCAD-US must not be used alone for primary diagnostic interpretation.
More Information

No
The summary describes statistical analysis and visualization of ultrasound data, but does not mention AI or ML algorithms.

No
The device is described as a software device intended to visualize and analyze statistical distributions of backscattered signals from tissue, providing conventional B-mode and color-mapped US-mode images for viewing and displaying backscatter statistical values. Its intended use is for primary diagnostic interpretation, not for treatment or therapy.

No

The device is intended to visualize and analyze statistical distributions of backscattered signals from tissue, but the documentation explicitly states that "The US-mode images displayed on AmCAD-US must not be used alone for primary diagnostic interpretation." This indicates it's a tool for analysis and visualization, not a standalone diagnostic device.

Yes

The device description explicitly states "AmCAD-US... is a software package". It processes data from an external, FDA-cleared ultrasound system and provides visualization and analysis, without including any hardware components itself.

Based on the provided information, AmCAD-US is not an In Vitro Diagnostic (IVD) device.

Here's why:

  • IVD Definition: IVD devices are used to examine specimens derived from the human body (like blood, urine, tissue samples) in vitro (outside the body) to provide information for diagnosis, monitoring, or screening.
  • AmCAD-US Function: AmCAD-US processes backscattered signals from ultrasound, which is an in vivo (within the body) imaging modality. It analyzes data obtained directly from the patient's body using an ultrasound system.
  • Intended Use: The intended use clearly states it visualizes statistical distributions of backscattered signals echoed by tissue compositions in the body. It does not involve the analysis of specimens taken from the body.
  • Device Description: The description reinforces that it quantifies and visualizes backscattered statistics contained in ultrasound image data obtained from an FDA-cleared general purpose ultrasound system. This data is generated in vivo.

Therefore, AmCAD-US falls under the category of medical imaging software, not an In Vitro Diagnostic device.

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)

Verification Tests: AmCad BioMed Corporation has conducted the software verification tests, including software unit test, software integration test, and software system test, to evaluate the safety and effectiveness of AmCAD-US. The software verification testing was performed to ensure that AmCAD-US meets all functional and specifications for its indication for use.

Non-clinical Validation Tests:
Phantom Study: AmCAD-US was applied to cell phantoms with different concentrations of one cell type and with different constitutions of mixed cell types. The results demonstrate the utility of the device in analyzing various cell compositions.
Animal Study: AmCAD-US was applied on 6 rats with liver fibrosis induced by dimethylnitrosamine (DMN) injection. The results demonstrate a strong correlation between the backscattered statistics provided by the device and the dosage of DMN injections, and the utility of the device in analyzing the variation of the tissue compositions in small animals.
Human tissue validation study: Two common ultrasound scanning modes (thyroid and abdomen) were applied. Two different FDA-cleared ultrasound systems were used. The result indicated that the device could be applied to various tissue parts in the human body and can be used with RF/Envelop data provided by various FDA-cleared ultrasound systems.
