DoseRight is intended to be used for automatic dose regulation during CT scanning for the purpose of obtaining the desired image quality at the lowest possible dose.

DoseRight is a software option to the CT Vision family of CT systems. These systems are whole body Computed Tomography (CT) systems which are diagnostic X-ray systems intended to produce cross-sectional images of the body by computer reconstruction of x-ray transmission of data from the same axial plane taken at different angles. They includes signal analysis and display equipment, patient and equipment supports, component parts and accessories which are used in combination with signal and image processing software to facilitate the relative localization of analomy with gray-scale representation of density relative to water utilizing Houndsfield indices with or without contrast mediums. They are used for the display, storage and analysis of digital diagnostic CT images. They are intended for use by a physician in the diagnosis and planning phases of patient conditions and treatment.

Device Description

DoseRight is a software option to the Philips CT Vision product family of computed tomography systems. The CT Vision products are whole body scanners. The CT Vision product family is comprised of the following systems. Each product has been cleared for commercial distribution via the referenced 510(k) submission.

· Philips CT Secura (previously named Tomoscan AV-NT, ref: K991278)
· Philips CT Secura MV (ref: K000819)
· Philips CT Aura (previously named Tomoscan CS, ref: K982631)

DoseRight is used to enable automatic dose regulation during scanning for the purpose of obtaining the desired image quality at the lowest possible dose. Using DoseRight, the dose required to attain a pre-determined image quality is calculated from the scanogram (scanned projection radiograph) of the patient and resultant scan parameters are then recommended to the user for the scan protocol. The user performs the scanogram in the normal way. At the comletion of the scanogram, and with DoseRight enabled, a mAs/KV combination is displayed to the user, which is the recommended combination to use in the scan protocol to achieve a pra-determined user defined image quality relative to patient diameter. However, if the user so chooses, this recommendation can be ignored and the user can proceed with the standard protocol.

AI/ML Overview

The provided document is a 510(k) summary for a device called "DoseRight," a software option for Philips CT Vision systems. It describes the intended use and substantial equivalence to a predicate device but does not contain information about acceptance criteria, specific performance metrics, or details of a study to prove the device meets acceptance criteria.

Therefore, I cannot provide the requested information. The document focuses on regulatory compliance and equivalence to an existing device rather than a detailed performance study.

INTENDED USE

DoseRight is intended to be used for automatic dose regulation during CT scanning for the purpose of obtaining the desired image quality at the lowest possible dose.

DoseRight is a software option to the CT Vision family of CT systems. These systems are whole body Computed Tomography (CT) systems which are diagnostic X-ray systems intended to produce cross-sectional images of the body by computer reconstruction of x-ray transmission of data from the same axial plane taken at different angles. They includes signal analysis and display equipment, patient and equipment supports, component parts and accessories which are used in combination with signal and image processing software to facilitate the relative localization of anatomy with gray-scale representation of density relative to water utilizing Houndsfield indices with or without contrast mediums. They are used for the display, storage and analysis of digital diagnostic CT images. They are intended for use by a physician in the diagnosis and planning phases of patient conditions and treatment.

SUBSTANTIAL EQUIVALENCE INFORMATION:

The DoseRight option is considered comparable and substantially equivalent to the following predicate device.

· SmartScan Option used in GE Medical System's HiSpeed CT/i CT System (ref: K964746)
The above-mentioned CT system has been cleared for commercial distribution via the referenced 510(k) submission.

SAFETY INFORMATION:

The DoseRight option introduces no new safety issues to the CT Vision family of CT systems other then those already known with these systems in which this type option is used. Computed tomography is a mature technology with which industry and users have many years of experience. These devices must comply with the appropriate sections of the Radiation Control for Health and Safety Act. The DoseRight option as part of the CT Vision family of CT systems and its associated labeling complies with the applicable requirements of the Federal X-ray Performance standards 21CFR 1020.30, 1020.33.

The Philips CT Vision family of CT systems with which the DoseRight option is used are designed to comply with the requirements of Underwriters Laboratories (UL) Standard for Safety of Medical Electrical Equipment (UL-2601) and be classified by Underwriters Laboratories or an equivalent test laboratory. They are also designed to comply with the requirements of IEC-601-1 (Medical Electrical Equipment).

The results of the hazard analysis, combined with the appropriate preventive measures taken indicate that the device is of minor level of concern as per the August 29, 1991 issue of the "Reviewer's Guidance for Computer Controlled Medical Devices Undergoing 510(k) Review".
