The CapIMAGE Gamma Camera System is intended to produce planar images depicting the anatomical distributions of single photon emitting radioisotopes in the human body within the energy range of 59kev to 167kev. The system provides software applications for processing, analyzing, and displaying medical images for interpretation by medical personnel.

The CapIMAGE Gamma Camera System is intended for examination (and diagnosis) of disorders and diseases in the thyroid gland, the heart and other small organs. The device is not interpretative. Data from the device are interpreted by medical personnel who, based on these, make the clinical diagnosis.

The CapIMAGE is a mobile Small Field of View (SFOV) gamma camera system utilizing a scintillation detector to detect gamma rays. The CapIMAGE is designed to be manually transported and deployed for scanning of patients in laying, sitting or standing positions. The system can operate powered from mains or from the internal battery source for at least 60 min.

Attenuation correction is a method where the emission images acquired during SPECT acquisitions are compensated for attenuation within the patient. The purpose of attenuation correction is to compensate for varying attenuation of gamma rays in the body.

The intended use of the c.cam Attenuation Correction option is to provide the customer with means to measure the attenuation of gamma rays within the body of a patient, when using a c.cam gamma camera system for SPECT studies, and to map the measured attenuation into images that can be used to compensate emission images for the attenuation. The c.cam-AC includes additional acquisition of data for scatter correction of these images.

The c.cam-AC is an attenuation correction device, which will be marketed as an optional device for the c.cam gamma camera.

C.cam gamma camera is a dual detector system and the attenuation correction device (two units) will be mounted opposite of the two detectors, one device on each detector. The attenuation correction device is formed as two housings each containing 14 line sources in fixed positions, shutter and all shutter control.

The following described functions are performed on both detectors simultaneously.
When the scanning is initiated the emission image and the transmission images are acquired sequentially. When the emission image has been acquired, a shutter, common for all sources, located in the device housing will open for exposure from 14 line sources (max. 20 mCi each 153 Gd with a total of max. 96 mCi). A collimated beam of gamma ray photons is focused on the opposite detector field of view to create the transmission images of the patient placed in the field of view of the detector. Having acquired both emission and transmission images, the data for emission, transmission, emission scatter and transmission scatter are stored in one dataset. A scaled version of the blank transmission scan is stored in another dataset. The complete study can be export via DICOM to the OEM customer provided processing station for later processing and reviewing.

I apologize, but the provided text from the FDA 510(k) letter for the CardioMD-AC device does not contain the detailed information necessary to answer your request regarding acceptance criteria and the study proving the device meets those criteria.

The 510(k) letter is a regulatory document confirming substantial equivalence to a predicate device, allowing the CardioMD-AC to be marketed. It does not typically include:

• A table of acceptance criteria and reported device performance: This type of data would be found within the 510(k) submission itself, not the FDA's decision letter.
• Sample sizes, data provenance, or expert qualifications for test sets.
• Details on adjudication methods.
• Information about MRMC comparative effectiveness studies.
• Results of standalone algorithm performance studies.
• Specifics on ground truth types or how ground truth was established for training and test sets.
• Training set sample sizes.

The letter primarily focuses on:

• Confirming the device name and regulation details.
• Stating the FDA's finding of substantial equivalence.
• Outlining regulatory responsibilities for the manufacturer.
• Providing the "Indications for Use" statement (on page 2 of the provided text, which states the purpose of attenuation correction and its intended use with the CardioMD gamma camera system).

To obtain the information you're looking for, you would typically need to review the full 510(k) marketing submission document, which may be publicly available through the FDA's website, though often in redacted form.

Virgo is an emission computed tomography system intended to detect the location and distribution of gamma ray radionuclides in the body and produce cross-sectional images through computer reconstruction of the data. The device includes display equipment, patient and equipment parts, and accessories.

Virgo is primarily intended for cardiac applications but the Virgo design also supports non-cardiac procedures of the patient's chest region and body extremities. Virgo supports radionuclides within the energy range of 60 -170 keV

The Virgo system design comprises a gantry supporting a fixed 90 degree dual head detector and a patient chair. The Virgo system is operated through interaction with a graphical user interface situated on the acquisition PC and a dedicated Virgo hand controller.

The provided text describes acceptance criteria and reported device performance for the Virgo Gamma Camera System. The study conducted to prove the device meets these criteria is a non-clinical test following documented verification plans, often adhering to the NEMA Standard NU 1-1994.
