New amendment added #1: Dear Bidders,Please be advised that RFQ/2026/63094 has been revised and amended.Kindly refer to the document RFQ/2026/63094_RFQ Amendment 01_Summary of Revisions.pdf  for a summary of the changes made to the initial RFQ documents package.Thank you.

New clarification added: Dear UNOPS team, 1.    Having reviewed the technical requirements for the ultrasound system, we kindly request a modification to the following parameter of LOT 2, 3.15    Tissue Doppler max frames per second (fps), at least: 800.Requested Revision: Tissue Doppler max frames per second (fps), at least: 750Tissue Doppler Imaging (TDI) at 750 fps provides an exceptionally high temporal resolution (approx. 1.33 ms per frame). The difference between 750 fps and 800 fps is less than 0.1 milliseconds, which has zero clinical significance and does not affect diagnostic accuracy or cardiac strain analysis. Setting the limit strictly at 800 fps creates an unnecessary barrier, as many premium ultrasound platforms from leading global manufacturers top out around 750–760 fps.Lowering this threshold to 750 fps will prevent a non-competitive, single-vendor tender, expand the number of eligible participants, and ensure maximum cost-efficiency through fair market competition./Dear bidder,Thank you for the clarifications raised. Please see the response below:Lot 2 Ultrasound imaging system with color Doppler mapping and sector phased array transducerItem 3.15  Tissue Doppler max frames per second (fps), at least: 800.Upon review, it is acknowledged that a maximum Tissue Doppler Imaging (TDI) frame rate of 750 fps provides very high temporal resolution and is sufficient to support the intended clinical applications of the ultrasound imaging system, including assessment of rapid myocardial motion and cardiac function. Therefore, the requirement will be amended as follows:Tissue Doppler maximum frame rate: at least 750 fps.Thank you.Procurement team.

New clarification added: Dear Representatives of UNOPS!Please answer a few questions about LOT 1: 1.      Items 3.14: There is a requirement in the Technical Bid Form (Lot 1) that cannot be verified using standard manufacturer documentation. The Fujifilm ultrasound system we intend to offer features a B-mode frame rate (FPS) that is three times higher than your minimum requirement. While it includes TDI mode, the manufacturer does not explicitly specify separate FPS values for this mode in its public datasheets, as requested in item 3.14. Could this item be removed from the technical requirements? 2.      Item 3.8 “CWD PRF range, Hz, at least: 1500-52000 Hz” and item 3.11 “CWD PRF range, Hz, at least: 500-10000 Hz” have the same description but with different numbers. We suppose it is mistype. Please, clarify these requirements. 3.      Item 3.23 (3D image generated from a 2D image): Could you please clarify the exact clinical or technical requirement for this item? There are two common methods to generate 3D images from 2D data:·        Method 1 (Freehand 3D): Utilizing standard 2D probes and moving them manually to acquire a volume. This method is outdated, rarely used in clinical practice due to its high dependence on operator experience, and typically yields poor data quality.·        Method 2 (Automated 3D): Utilizing mechanical volume probes that house an internal motor to automatically sweep the array and collect precise volume data.Since "Freehand 3D" is obsolete and mechanical volume probes are not included in the required transducer set, could this requirement be removed entirely? This would prevent unnecessary cost increases and foster broader competition. 4.     Item 9.2 (Linear transducer): Could you please specify the primary clinical application intended for this probe and adjust the specifications accordingly? We can offer a linear probe that meets all technical criteria but it has more wide frequency range 5-18 MHz than in the requirement 5-14 MHz, but this probe is ideal solution for superficial examination on in the near field (not more 6 cm), but the doctor can face some difficulties in visualization more deep structures for example big mammary or thyroid of people with dick neck. If so we would recommend probe with 5-13 MHz which doesn’t suit your requirement in range only for 1 MHz but it is more universal probe. Knowing the probe purpose will help to offer more suitable probe./Dear Bidder,Thank you for your question. Please review responses listed below:1)Question 1Lot 1Requirement 3.14 Tissue Doppler max frames per second (fps), at least: 300The requirement for a Tissue Doppler Imaging (TDI) frame rate of at least 300 frames per second (fps) has been established based on the intended clinical use of the expert-class ultrasound system.A high TDI frame rate is essential to provide adequate temporal resolution for accurate assessment of myocardial motion during the rapid phases of the cardiac cycle. It enables reliable measurement of myocardial velocities, improves the evaluation of systolic and diastolic function, and reduces motion-related artifacts, thereby supporting high-quality echocardiographic examinations.Furthermore, performance characteristics may be demonstrated through official manufacturer technical documentation, product specifications, application manuals, or other manufacturer-issued evidence.Therefore, the requirement will remain unchanged.2)Question 2Lot 1Requirements 3.8 and 3.11Thank you for bringing this to our attention.You are correct that there is a typographical error in Requirement 3.11. The requirement should refer to Color Doppler PRF range rather than Continuous Wave Doppler (CWD) PRF range.Accordingly, the requirement will be amended as follows:Requirement 3.11: Color Doppler PRF range, Hz, at least: 500–10000 Hz.Requirement 3.8 remains unchanged as follows:Requirement 3.8: CWD PRF range, Hz, at least: 1500–52000 Hz.The technical documents will be amended accordingly.3)Question 3Lot 1Requirement 3.21 – 3D image generated from the 2D image: PossibilityThank you for your question.The requirement under Item 3.21 refers to the availability of software-based Freehand 3D reconstruction functionality, which enables the generation of a 3D image from a sequence of 2D images acquired using conventional, non-volumetric transducers.The purpose of this functionality is to provide the user with the capability to perform basic 3D visualization and reconstruction using standard transducers when clinically appropriate. Such functionality may support improved spatial visualization of anatomical structures and lesions and serves as a useful adjunct to conventional 2D imaging in selected clinical applications.The availability of advanced software imaging and post-processing tools for expert-class diagnostic ultrasound system is considered an appropriate requirement. Since the functionality can be provided without additional dedicated 3D hardware or probes, it does not impose an undue restriction.Therefore, the requirement will remain unchanged.4)Question 4Lot 1Requirement 9.2 – Linear TransducerThe linear transducer is intended for general-purpose examinations, including peripheral vascular imaging, superficial organs and structures (such as the thyroid and breast), musculoskeletal examinations, and soft tissue imaging.The specified frequency range of at least 5.0–14.0 MHz was selected to provide an appropriate balance between penetration and spatial resolution across these intended clinical applications. The requirement is intended to ensure that the transducer is suitable for a broad range of superficial imaging examinations rather than being optimized for only a specific clinical application or imaging depth.The specified frequency range represents the minimum acceptable performance. Probes offering a wider frequency range are acceptable, provided they meet or exceed the minimum technical requirements and are capable of supporting the intended clinical applications.Therefore, the requirement will remain unchanged.Thank you.Procurement team. 

New clarification added: Dear Representatives of UNOPS!Please answer a few questions:1.      Items 3.12 & 3.15: There are several requirements in the Technical Bid Form (Lot 2) that cannot be verified using standard manufacturer documentation. The Fujifilm ultrasound system we intend to offer features a B-mode frame rate (FPS) that is three times higher than your minimum requirement. While it includes Color and TDI modes, the manufacturer does not explicitly specify separate FPS values for these modes in its public datasheets, as requested in Items 3.12 and 3.15. Could these two items be removed from the technical requirements?2.       Item 3.23 (3D image generated from a 2D image): Could you please clarify the exact clinical or technical requirement for this item? There are two common methods to generate 3D images from 2D data:·        Method 1 (Freehand 3D): Utilizing standard 2D probes and moving them manually to acquire a volume. This method is outdated, rarely used in clinical practice due to its high dependence on operator experience, and typically yields poor data quality.·        Method 2 (Automated 3D): Utilizing mechanical volume probes that house an internal motor to automatically sweep the array and collect precise volume data.Since "Freehand 3D" is obsolete and mechanical volume probes are not included in the required transducer set, could this requirement be removed entirely? This would prevent unnecessary cost increases and foster broader competition.3.      Item 3.31 (Quantitative analysis of vascularization in Power mode): To utilize this feature, a 3D software option and specialized volume probes are required—neither of which are specified in your current technical requirements. Furthermore, this advanced option is not supported by all manufacturers. To promote fair and open competition, could this requirement be removed?4.       Item 9.2 (Linear transducer): Could you please specify the primary clinical application intended for this probe and adjust the specifications accordingly? We can offer a linear probe that meets all technical criteria except for the requested frequency range of "at least 3–12 MHz." Specifically, we can offer a single-crystal linear probe with 480 elements and a frequency range of 2–9 MHz, which is an ideal solution for deep vessel examinations. Alternatively, we can offer a standard universal probe (192 elements) that matches your requested frequency range but is not single-crystal. Would the committee accept the 2–9 MHz single-crystal probe as an equivalent or better to offer non single crystal probe which suits frequency range and ignore q-ty of elements?/Dear Bidder,Thank you for your clarification request. Please review clarification responses below.1)Question 1Lot 2 Ultrasound imaging system with color Doppler mapping and sector phased array transducerRequirement # 3.12 and 3.15:High frame rate in Color Doppler is an important performance parameter for expert-class ultrasound systems, particularly considering that the equipment is intended for a wide range of examinations. High temporal resolution in Color Doppler improves visualization of rapid hemodynamic events, supports assessment of turbulent flow, and is important in the evaluation of cardiac valve defects and vascular stenosis and related events.Similarly, high frame rate in Tissue Doppler Imaging (TDI) is important for accurate assessment of rapid myocardial motion during systole and diastole. Adequate temporal resolution helps prevent motion blurring and supports more accurate measurement of tissue velocities, including in the assessment of cardiac function.Therefore, the stated requirements are considered clinically relevant and shall remain applicable.Additionally, compliance may be demonstrated through official manufacturer documentation, technical data sheets, manufacturer-issued confirmation letters, or other equivalent manufacturer evidence confirming that the proposed system meets the required Color Doppler and Tissue Doppler frame rate performance.The requirement remains unchanged.2)Question 2; Lot 2 Ultrasound imaging system with color Doppler mapping and sector phased array transducerRequirement 3.23:3D image generated from the 2D image: AvailabilityThe requirement under Item 3.23 refers to the availability of Freehand 3D reconstruction functionality, which allows generation of a 3D image from a sequence of 2D images acquired using conventional, non-volumetric transducers.The requirement does not imply the use of dedicated mechanical volume probes or automated volumetric acquisition technology. No additional volumetric transducers beyond those specified in the tender requirements are required to meet this criterion.The purpose of this requirement is to provide the user with the ability to perform basic 3D visualization and reconstruction using standard transducers when clinically appropriate.Therefore, the requirement is considered appropriate for the intended clinical applications and does not impose a requirement for additional dedicated 3D hardware. The requirement shall remain unchanged.3)Question 3; Lot 2 Ultrasound imaging system with color Doppler mapping and sector phased array transducerRequirement 3.31 (Quantitative analysis of vascularization in Power mode)Quantitative assessment of tissue vascularization is an important diagnostic tool that converts subjective visual assessment of blood flow into objective quantitative information, supporting more accurate evaluation of inflammatory processes, vascular pathology, and tissue perfusion. Such functionality may be useful in examinations of parenchymal organs, musculoskeletal structures, and vascular lesions.For clarification, the requirement refers to quantitative analysis of vascularization in Power Doppler mode and does not require dedicated volumetric probes or 3D acquisition technology. Compliance may be achieved using conventional transducers and software tools provided by the ultrasound system.Furthermore, this functionality is available and is not considered manufacturer-specific technology.Therefore, the requirement under Item 3.31 will remain unchanged.4)Question 4;Lot 2 Ultrasound imaging system with color Doppler mapping and sector phased array transducerRequirement 9.2 (Linear transducer) AvailabilityThank you for your clarification question request.While a transducer with a frequency range of 2–9 MHz may provide good performance for deep vascular imaging, the upper frequency limit of 9 MHz is considered insufficient for optimal imaging of superficial structures such as the breast, thyroid gland, and other small parts. Therefore, the requirement for a frequency range of at least 3.0–12.0 MHz remains unchanged.At the same time, following review of the requirement related to transducer technology, it was confirmed that 9.2.5 Single Crystal technology will be removed.Thank you.Procurement team.
