The document describes a stereotactic biopsy system that uses fixed detectors and geometric calculations for 3D localization, with no mention of AI or ML in the device description, intended use, or performance studies.
No.
The device is described as a gamma camera system intended for diagnostic imaging and guiding interventional procedures (biopsy and pre-surgical localization) by accurately locating lesions. It does not actively treat or cure a disease.
Yes
The "Intended Use / Indications for Use" section explicitly states, "The Discovery NM 750b Gamma Camera is intended for diagnostic imaging of the breast and other small body parts."
No
The device description explicitly states that the Discovery NM750b Biopsy system includes both hardware and software components.
Based on the provided text, the Discovery NM 750b Gamma Camera and its optional Biopsy system are not an In Vitro Diagnostic (IVD) device.
Here's why:
- IVD Definition: In Vitro Diagnostic devices are used to examine specimens (like blood, urine, or tissue) taken from the human body to provide information for diagnosis, monitoring, or screening.
- Device Function: The Discovery NM 750b Gamma Camera and Biopsy system work by detecting and imaging the distribution of radioisotopes within the human body. They are used for in vivo imaging and guidance for procedures, not for analyzing samples outside the body.
The device's intended use and description clearly indicate it's an imaging and interventional guidance system that operates directly on the patient.

Intended Use / Indications for Use
The Discovery NM 750b Gamma Camera is intended to measure and image the distribution of selected single photon emission radioisotopes in the human body to aid in the evaluation of lesions. The resultant images are intended to be reviewed by qualified medical professionals. The Discovery NM 750b Gamma Camera is intended for diagnostic imaging of the breast and other small body parts. The Discovery NM 750b Gamma Camera when used for breast imaging is intended as an adjunct to mammography or other breast imaging modalities (it is not intended for primary screening of the population). The Discovery NM 750b Gamma Camera is indicated for planar and dynamic planar scintigraphy in the energy range 80-200ke V for the detection and display of radioisotope tracer uptake in patients of all ages.
When used with the optional Discovery NM 750b Biopsy system, the Discovery NM 750b is designed to accurately locate, in three dimensions, lesions in the breast using information derived from stereotactic pairs of two-dimensional images. It is intended to provide guidance for interventional purposes such as biopsy and pre-surgical localization.

Device Description
The Discovery NM 750b Biopsy system is an optional accessory for the Discovery NM 750b gamma camera (K102231) that utilizes stereotactic imaging to help guide invasive procedures. It is intended for 3D lesion localization to provide the physician image guidance for vacuum assisted needle biopsy of breast lesions determined to be suspicious through molecular breast imagine or other imaging.
The Biopsy system uses a pair of CZT "biopsy" detectors with fixed stereotactic positions. These two detectors acquire pair of anqulated two-dimensional images that are used in determining the 3D localization of the pre-identified suspicious lesion.
The Discovery NM750b Biopsy system includes hardware and software components, which auides the user throughout the biopsv work-flow. The hardware components enable the use of a variety of off-the-shelf biopsy vacuum needles.
In addition to the hardware components, the biopsy system accessory includes software components which, in part, through the user interface help quide the user stepwise through the biopsy workflow. The Discovery NM 750b Biopsy system is designed to support a variety of commercially available vacuum assisted biopsy devices and needles.

Description of the test set, sample size, data source, and annotation protocol
The safety and performance of the Discovery NM750b Biopsy system was demonstrated through full verification testing, additional engineering bench performance testing using phantoms, and simulated clinical use testing performed by physicians using a commercially available breast biopsy phantom and a supporting phantom. This phantom setup had radiotracer-injected simulated lesions against a uniform radioactive background. The activities of the lesions and background were set to be representative of actual clinical use. The simulated clinical testing performed with the software driven workflow, provided data from cases that represent a broad range of clinically relevant scenarios taken variables such as lesion size, lesion position, gantry orientation, VAD type. Worst case and challenging scenarios were included.

The safety and performance of the Discovery NM750b Biopsy system was demonstrated through full verification testing, additional engineering bench performance testing using phantoms, and simulated clinical use testing performed by physicians using a commercially available breast biopsy phantom and a supporting phantom. This phantom setup had radiotracer-injected simulated lesions against a uniform radioactive background. The activities of the lesions and background were set to be representative of actual clinical use.
The simulated clinical testing performed with the software driven workflow, provided data from cases that represent a broad range of clinically relevant scenarios taken variables such as lesion size, lesion position, gantry orientation, VAD type. Worst case and challenging scenarios were included.
These tests were performed to provide the requisite data to substantiate performance, claims, and ultimately substantial equivalence. The testing demonstrated that the Discovery NM750b Biopsy system performs according to specifications and functions as intended.
- Based on conformance to standards; development under GE Conclusion: Healthcare's quality management system and design controls; successful verification/validation testing; well established stereotactic imaging principles; additional bench performance testing; and the physician-performed clinical simulation testing using an established, commercially available biopsy simulation phantom modified to better represent nuclear medicine characteristics, GE Healthcare believes that the Discovery NM 750b Biopsy system accessory is substantially equivalent to its predicate devices [Discovery NM 750b (K102231) and GammaLoc (K082588)] and reference device (Senographe Stereo (K040125)). Therefore GE concludes that the Discovery NM 750b Biopsy is safe and effective for its intended use
