The system can then display, process and store the reconstructed slices. ## Device Story Pronto is a third-generation computed tomography (CT) system. It utilizes a rotating gantry containing an x-ray tube and solid-state detector to collect x-ray transmission data at multiple angles around a patient. Slip-ring technology enables continuous rotation. High-speed electronics mathematically reconstruct axial cross-sectional images from the collected data. The system includes a patient table, high-frequency x-ray generator, and a PC-based workstation running Windows NT. Used in clinical settings, the device is operated by trained personnel. Reconstructed images are displayed on the workstation, printed, or archived. The system assists clinicians in visualizing internal body structures for diagnostic decision-making. ## Clinical Evidence Bench testing only. No clinical data provided. ## Technological Characteristics Third-generation CT geometry; rotating gantry with slip-ring technology; solid-state x-ray detector; high-frequency x-ray generator; PC-based workstation (Intel Pentium, Windows NT). Non-invasive. Designed to comply with 21 CFR safety standards. ## Regulatory Identification A computed tomography x-ray system is a diagnostic x-ray system intended to produce cross-sectional images of the body by computer reconstruction of x-ray transmission data from the same axial plane taken at different angles. This generic type of device may include signal analysis and display equipment, patient and equipment supports, component parts, and accessories. ## Predicate Devices - Philips Medical Systems Secura ([K991278](/device/K991278.md)) ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

MAR 2 2 2002 KO14240 ## Submitter: 1.1. Hitachi Medical Systems America, Inc. 1959 Summit Commerce Park Twinsburg, OH 44087 Phone: (847) 463-2001 FAX: (847) 463-2011 ### 1.2. Manufacturing Facility: Hitachi Medical Corporation Kashiwa Works 2-1 Shintoyohuta, Kashiwa Kashiwa City Chiba Prefecture, Japan - 1.3. Contact: Robert H. McCarthy - Date: December 15, 2001 1.4. #### Device Name 2. - Computed Tomography System Classification Name: 2.1. Classification Number: 90JAK - 2.2. Trade/Proprietary Name: Pronto - Predicate Device: Philips Medical Systems Secura, 2.3. K 991278 #### 3. Device Description #### 3.1. Function The Pronto is a computed tomography system consisting of a gantry, computer operator's console, patient table, high frequency x-ray generator and accessories. Computed tomography (CT) is a radiographic method that uses a computer to reconstruct an image of a cross sectional plane of an object. The Pronto system utilizes "Third Generation" geometry with the x-ray tube and x-ray detector mounted on a rotating frame. A fan beam of x-rays generated by an x-ray tube mounted in the gantry passes through the patient and is detected by a solid state x-ray detector. The rotating frame containing the x-ray tube and x-ray detector rotate concentrically {1}------------------------------------------------ about the patient utilizing slip ring technology. As the x-ray tube and detector move around the patient, data is collected at multiple angles. A cross-sectional image is then reconstructed using the collected data by specialized high speed electronics. The reconstructed images can then be viewed on the computer workstation, printed on a printer or transferred to an archive or remote viewing station. The high voltage required for the xray tube is generated on the rotating frame with a high frequency transformer. The x-ray detector is similar in design to the predicate device. The computer workstation is PC based utilizing the latest Intel Pentium technology. The operating system is Windows NT. #### Device Intended Use: 4. - The intended use of the Pronto is to produce cross-sectional images of the 4.1. body by using high-speed electronics to mathematically reconstruct axial slices using data produced by x-ray transmission data from the same axial plane taken at different angles. The system can then display, process and store the reconstructed slices. #### Device Technological Characteristics: 5. - The characteristics of the Pronto Computed Tomography System compare 5.1. substantially with the Philips Medical Systems Secura predicate device, in both materials used, technology applied, and functional methodology. Differences of note do not affect safety and effectiveness of the device, intended use, or application methods. The device operates in a manner substantially equivalent to other cleared devices in this category, and performs as well as the predicate Secura. #### 5.2. Safety The Pronto is a non-invasive device. It has been designed to comply with applicable safety standards and the applicable sections of 21CFR. An initial product report defined by 21CFR 1002.10 will be submitted prior to the first Pronto shipment. The results of the hazard analysis indicate that the device is of minor level of concern as defined in the "Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices". {2}------------------------------------------------ # DEPARTMENT OF HEALTH & HUMAN SERVICES Public Health Service Food and Drug Administration 9200 Corporate Boulevard Rockville MD 20850 MAR 22 200 Mr. Robert McCarthy Director of New Technology Hitachi Medical Systems America, Inc. 1959 Summit Commerce Park TWINSBURG OH 44087 Re: K014240 Trade/Device Name: Pronto Regulation Number: 21 CFR 892.1750 Regulation Name: Computed tomography x-ray system Regulatory Class: II Product Code: 90 JAK Dated: December 14, 2001 Received: December 26, 2001 # Dear Mr. McCarthy: We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA).
