Abstract
Description
Technical Field
[0001] This application claims the benefit of U.S. Provisional Patent Application No. 63 / 512,899, filed Jul. 10, 2023, the entire disclosure of which is incorporated herein by reference.
[0002] The present disclosure generally relates to devices, systems, and methods for delivering contrast agents to patients and for use in medical imaging procedures, and more particularly to devices, systems, and methods for delivering accurate and / or small amounts of contrast agent and / or standard amounts of contrast agent to enhance images during medical imaging procedures.
Background Art
[0003] Infusion systems, such as fluid infusion systems (e.g., medical fluid delivery systems), can be used by medical personnel in medical diagnostic procedures and / or medical treatment procedures, or in medical procedures including both. For example, a medical professional can use a fluid infusion system to inject one or more medical fluids into a patient. Fluid infusion systems can be used for the pressure infusion of medical fluids, such as radiographic contrast materials (e.g., contrast agents), and / or flushing agents, such as saline (e.g., normal saline, 0.9% normal saline), in medical imaging procedures, such as angiography, computed tomography (CT), ultrasound, magnetic resonance imaging (MRI), positron emission tomography (PET), single photon emission computed tomography (SPECT), and hybrid imaging techniques such as SPECT / CT, PET / CT, and PET / MRI. Fluid infusion systems can also be used to deliver medical fluids or liquid medications to a patient during other procedures and / or treatments, including nuclear medicine imaging, molecular imaging, radiopharmaceutical injection, cardiovascular local treatment, and image-guided radiation therapy, such as MRI-guided linear accelerator (MR / LINAC). In some cases, a fluid infusion system is designed to deliver a fixed amount of medical fluid to a patient at one or more flow rates.
[0004] In medical treatment or procedures, the amount of medical fluid delivered to a patient may be measured in volume. In some cases, precise dose measurement may be performed on the patient for proper imaging, appropriate treatment, and / or to avoid adverse reactions, including complications to the patient's health. Furthermore, to avoid such adverse reactions, a partial dose (e.g., a micro-partial dose) of the medical fluid may be administered to the patient during the procedure.
[0005] However, research protocols, including medical fluid administration protocols and / or imaging protocols, are complex and therefore difficult for users to track and implement during medical fluid infusion and imaging procedures, including enhanced imaging procedures. Furthermore, fluid infusion systems may include larger injectors with larger volume syringes that do not provide adequate volume control or precise measurement of accurate doses of medical fluid for delivery to the patient during enhanced imaging procedures. Specifically, fluid infusion systems may enable partial dose (e.g., micro-partial dose) administration, but may be limited to such partial doses and do not provide the ability to deliver standard doses of medical fluid that may be required during enhanced imaging procedures. [Overview of the project] [Problems that the invention aims to solve]
[0006] In light of the above, there is a need for devices, systems, and methods for delivering precise (e.g., partial and / or standard) volumes of medical fluids, such as contrast agents, and for enhancing images during medical imaging procedures based on the delivery of precise volumes of medical fluids.

[0057] In a non-limiting embodiment, when automatically selecting a specific dose of contrast agent from multiple doses of contrast agent to be administered to a patient during an infusion procedure, the protocol management system can provide input to a machine learning model based on a request for inference to the machine learning model, and generate an output from the machine learning model based on the input, the output including a prediction of the dose of contrast agent to be administered to the patient during the infusion procedure. The input may include multiple features, which may include at least one of the following: patient weight, patient height, patient age, patient sex, patient body type, patient medical history, patient physiological status, patient physiological measurements, or any combination thereof.
[0058] Furthermore, non-limiting embodiments provide fluid injection systems and imaging systems, including an image acquisition or imaging device, a fluid injector, and associated components.

The protocol management system may utilize natural language and / or voice control that can be integrated into radiological diagnostic settings. Furthermore, the collected information may be translated into natural language (e.g., a given language) so that protocols can be immediately monitored and controlled by the appropriate individuals. Furthermore, the collected information may be in the native language of the speaker or the location where the procedure is being performed, and may be made available to local authorities in such language, and / or may be automatically translated into a common language for central analysis and memory.

In some non-limiting embodiments, one or more of the steps of process 400 are performed by another device or group of devices separate from or including the protocol management system 102, such as a data source (e.g., data source 104), a user device (e.g., user device 106, workstation device 206), a fluid injection system (e.g., fluid injection system 108, such as one or more devices of fluid injection system 108), a medical imaging system (e.g., medical imaging system 110, such as one or more devices of medical imaging system 110), and / or a hospital information system (e.g., hospital information system 112, such as one or more devices of hospital information system 112, hospital information system 212, such as one or more subsystems of hospital information system 212, etc.).
[0088] As shown in Figure 4, in step 402, process 400 may include determining the dose of medical fluid to be administered during the infusion procedure. The protocol management system 102 may determine whether to administer a standard dose or a partial dose of contrast fluid to the patient during the infusion procedure. In some non-limiting embodiments, the protocol management system 102 may determine the dose of medical fluid to be administered during the infusion procedure based at least in part on patient-related healthcare data. The protocol management system 102 may receive healthcare data from multiple data sources 104. In some non-limiting embodiments, the data source 104 may include at least one of the following: an electronic health record (EHR) system, an electronic medical record (EMR) system, a patient treatment tracking system, a hospital information system (HIS), a medical imaging information system, a radiographic image analysis system, and / or an image archiving and communication system (such as a picture archiving and communication system (PACS)). Additionally or alternatively, data source 104 may include devices related to equipment such as medical imaging systems (e.g., imaging scanners), fluid injection systems (e.g., fluid injectors), communication equipment related to medical devices (e.g., wearable medical devices such as handheld medical devices and portable health sensors), and / or devices related to patients (e.g., user devices such as computing devices operated by patients). In some non-limiting embodiments, data source 104 may include one or more sensors, one or more diagnostic devices (e.g., bedside diagnostic devices), and / or one or more monitoring devices (e.g., bedside patient monitoring devices), such as the systems disclosed in U.S. Patent Application No. 17 / 921,245, filed April 30, 2021, and granted as U.S. Patent No. 11,896,352, the disclosures of which are incorporated herein by reference in their entirety.
[0089] In some non-limiting embodiments, patient-related healthcare data may include medical record data related to the patient's medical records, protected health information related to the patient, demographic information related to the patient, identification data related to the patient's identifier, data related to patient examination procedures (e.g., fluid infusion procedures and / or medical imaging procedures performed on the patient), such as data related to contrast fluids provided during fluid infusion procedures, the gauge of the catheter used during fluid infusion procedures, and fluid infusion protocols for fluid infusion procedures. In some non-limiting embodiments, the protocol management system 102 may store patient-related healthcare data in a data structure (e.g., a database). For example, the protocol management system 102 may store patient-related healthcare data in a data structure along with the patient's unique identifier. In some non-limiting embodiments, patient-related healthcare data may include the patient's imaging history. For example, if the patient has undergone an imaging procedure within the preceding 24 hours, the use of a partial dose of contrast agent may be instructed to avoid inducing iodine overload in the patient. Furthermore, if the patient has previously undergone imaging procedures and a partial dose of contrast agent was initially used, and the initial dose percentage of contrast agent was insufficient for the imaging procedure (e.g., a diagnostic scan), a larger dose percentage can be indicated or selected for the current imaging procedure. In some non-limiting embodiments, the results of the imaging procedure (e.g., image analysis results of images generated according to the imaging procedure using a partial dose of contrast agent (e.g., a low-dose scan)) may be captured by the protocol management system 102 and included in the healthcare data (e.g., as part of the procedure data record). For example, the results of the imaging procedure may include details about the previous procedure, such as "partial dose (e.g., low dose) successful, initial partial dose unsuccessful, further partial dose required," or "initial partial dose unsuccessful, standard dose required." This information can be used for future patient imaging procedures and / or as part of a training record dataset for any machine learning algorithm for partial dose calculation.
[0090] In some non-limiting embodiments, the protocol management system 102 can retrieve patient-related healthcare data from at least one of a plurality of data sources based on a patient-related identifier. For example, the protocol management system 102 can transmit a patient-related identifier (e.g., a unique patient identifier, such as a unique patient identifier for patient medical records) to a data source 104, such as a hospital information system, and the protocol management system 102 can receive patient-related healthcare data from the data source 104. In some non-limiting embodiments, the data source 104 can receive a patient-related identifier, retrieve patient-related healthcare data based on the identifier, and transmit the patient-related healthcare data to the protocol management system 102. In some non-limiting embodiments, the identifier may be related to the patient's patient record (e.g., the patient's patient record stored in the patient treatment tracking system 212A of the hospital information system 212).
[0091] In some non-limiting embodiments, the protocol management system 102 can generate patient profiles. For example, the protocol management system 102 can generate patient profiles based on healthcare data related to the patient. In some non-limiting embodiments, the protocol management system 102 can generate patient profiles based on demographic information and / or protected health information related to the patient.
[0092] In some non-limiting embodiments, the protocol management system 102 can select a specific dose of contrast fluid from multiple doses of contrast fluid to be administered to the patient during an infusion procedure. In some non-limiting embodiments, the protocol management system 102 can automatically select a dose of medical fluid to be administered to the patient during an infusion procedure based on the results of inference by a machine learning model. In some non-limiting embodiments, the protocol management system 102 can provide input to a machine learning model based on a request for inference to the machine learning model, and the input may include multiple features. For example, the multiple features may include at least one of the following: patient weight, patient height, patient age, patient body type and / or proxy of patient body type (e.g., physical characteristics, body type, build, body surface area, weight, height, body mass index (BMI), lean body mass, etc.), patient medical history, patient physiological status, patient physiological measurements (e.g., heart rate, cardiac output, ejection fraction, respiratory rate, etc.), or any combination thereof. In some non-limiting embodiments, the multiple features may further include the patient's body surface area, body mass index (BMI), disease status and condition. For example, in patients with renal disease and poor renal function (e.g., as measured by a low glomerular filtration rate (GFR) and / or high creatinine levels), it is often preferable to minimize the iodine dose during CT or angiography medical imaging procedures. In some non-limiting embodiments, the features may further include results from previous imaging, previous study results, previous test results, laboratory values from blood, urine, etc., and any other data. In some non-limiting embodiments, one or more of the features may be automatically extracted from images acquired by the protocol management system 102 or previously acquired images (e.g., native scan, scout scan, etc.), and may be quantitative or qualitative features, radiomic features, etc. In some non-limiting embodiments, the protocol management system 102 may determine inputs based on healthcare data received from multiple data sources 104.In some non-limiting embodiments, the protocol management system 102 can generate outputs from a machine learning model based on inputs, and these outputs may include predictions of the dose of contrast fluid to be administered to the patient during the infusion procedure. In some non-limiting embodiments, when selecting a specific dose of contrast fluid to be administered during the infusion procedure, the protocol management system 102 can determine whether to administer a standard dose or a partial dose of the contrast fluid to the patient during the infusion procedure.
[0093] As shown in Figure 4, in step 404, process 400 may include executing an infusion protocol for the infusion procedure. For example, the protocol management system 102 may automatically execute an infusion protocol for the infusion procedure based on determining the dose of medical fluid to be administered during the infusion procedure and selecting a specific dose of contrast fluid from multiple doses of contrast fluid, and the infusion protocol may include a specific dose. In some non-limiting embodiments, the protocol management system 102 may automatically execute an infusion protocol for the infusion procedure based on determining that a partial dose of contrast fluid will be administered during the infusion procedure and selecting a specific partial dose of contrast fluid from multiple doses of contrast fluid, and the infusion protocol may include a specific partial dose. In some non-limiting embodiments, the protocol management system 102 may automatically execute an infusion protocol for the infusion procedure based on determining that a standard dose of contrast fluid will be administered during the infusion procedure and selecting a specific standard dose of contrast fluid from multiple doses of contrast fluid, and the infusion protocol may include a specific standard dose.
[0094] In some non-limiting embodiments, the protocol management system 102 is associated with a fluid infusion system (e.g., fluid infusion system 108, fluid infusion system 208) including a fluid injector (e.g., fluid injector 208A), and the fluid injector includes a partial-dose fluid infusion component and a standard-dose fluid infusion component. In such embodiments, the protocol management system 102 can automatically execute an infusion protocol for an infusion procedure based on determining whether a partial dose of the contrast fluid is administered by the partial-dose fluid infusion component during the infusion procedure to the patient, or whether a standard dose of the contrast fluid is administered by the standard-dose fluid infusion component during the infusion procedure to the patient. In some non-limiting embodiments, the protocol management system 102 can automatically execute an infusion protocol for an infusion procedure by controlling the partial-dose fluid infusion component to administer a partial dose of the contrast fluid during the infusion procedure to the patient.
[0095] In some non-limiting embodiments, the partial-dose fluid injection component includes a partial-dose fluid injection pump, and the protocol management system 102 automatically executes an injection protocol for an injection procedure by operating the partial-dose fluid injection pump. In some non-limiting embodiments, the protocol management system 102 can operate the partial-dose fluid injection pump by receiving fluid flow data from a sensor, determining the fluid flow rate in the fluid path based on the fluid flow data received from the sensor, and outputting a control signal to the partial-dose fluid injection pump. In some non-limiting embodiments, the protocol management system 102 can operate the partial-dose fluid injection pump by receiving fluid data from a sensor, including an indication of whether air is present in the fluid path, determining whether a threshold amount of air is present in the fluid path based on the fluid data received from the sensor, and outputting a control signal to the partial-dose fluid injection pump based on the determination that air is present in the fluid path. In some non-limiting embodiments, the protocol management system 102 can operate the partial-dose fluid injection pump by receiving contrast fluid concentration data from a sensor, determining the concentration of the contrast fluid in the fluid path based on the contrast fluid concentration data received from the sensor, and outputting a control signal to the partial-dose fluid injection pump. For example, the fluid protocol management system 102 can operate a partial-dose fluid injection pump disclosed in U.S. Patent Application No. 09 / 267,238, filed on March 12, 1999, and granted as U.S. Patent No. 6,317,623, the disclosure of which is incorporated herein by reference in its entirety.
[0096] In some non-limiting embodiments, the fluid injector may include one or more fluid injection pumps and one or more fluid sources. In some non-limiting embodiments, the fluid injector may include one or more fluid injection pumps and two or more fluid sources. In some non-limiting embodiments, the fluid injector may include two or more fluid injection pumps and two or more fluid sources. In some non-limiting embodiments, the fluid injection pump (e.g., a syringe-based pump) may include a reservoir, a plunger, and a drive member. In some non-limiting embodiments, the fluid injection pump (e.g., a peristaltic pump or a gear pump) may include a tube, a rotating member, and a drive member. In some non-limiting embodiments, the protocol management system 102 can automatically execute an injection protocol for an injection procedure by receiving an injection protocol for the injection procedure and associated injection protocol data. The protocol management system 102 can receive injection protocol data from multiple data sources 104. In some non-limiting embodiments, the injection protocol data may include one or more instructions relating to the injection procedure. In some non-limiting embodiments, the protocol management system 102 can determine control parameters for a drive member based on injection protocol data and can output a control signal to the drive member to actuate the drive member and deliver a selected dose of contrast fluid to the patient, the control signal may be based on the control parameter. For example, the control parameter may include a specific length or increment of time, a specific linear distance, or a specific number of rotations at which the protocol management system actsuate the drive member, and the control parameter may correspond to the delivery of a specific dose, such as a selected dose of contrast fluid for the injection procedure.
[0097] As shown in Figure 4, in step 406, process 400 may include generating images of the patient's body. For example, the protocol management system 102 may generate images of areas of the patient's body based on automatically executing an injection protocol. In some non-limiting embodiments, the protocol management system 102 may communicate with medical imaging systems (e.g., medical imaging system 110, medical imaging system 210, e.g., their components) to generate images of the patient's body. In some non-limiting embodiments, the medical imaging system (e.g., medical imaging scanner) may include devices and components specific to a particular imaging procedure and the type of image to be generated, including angiography, computed tomography (CT), ultrasound, magnetic resonance imaging (MRI), positron emission tomography (PET), single-photon emission tomography (SPECT), hybrid imaging techniques such as SPECT / CT, PET / CT, PET / MRI, and / or other imaging procedures.
[0098] In some non-limiting embodiments, the protocol management system 102 can receive imaging data related to the imaging protocol from multiple data sources 104. In some non-limiting embodiments, the protocol management system 102 can provide the imaging data to a medical imaging system to generate images of areas of the patient's body. In some non-limiting embodiments, the imaging data may include features such as the type of image acquired by the imaging system, the location on the patient's body where the image is acquired, the size of the image acquired, the duration of the imaging exposure where the image is acquired (e.g., the time elapsed since the patient was exposed to light, radiation, or other energy source), the duration of the body's exposure to a contrast fluid where the image is acquired (e.g., the time elapsed since the contrast fluid was administered), and / or any combination thereof. In some non-limiting embodiments, the imaging data may include source characteristics relating to the associated imaging procedure. For example, in the case of CT imaging, the source characteristics may include energy level (kVp) and radiation dose (mAs), and in the case of MRI imaging, the source characteristics may include static magnetic field strength, pulse sequence, and acquisition model used. In some non-limiting embodiments, the protocol management system 102 may generate commands for generating images of body regions and / or provide commands to the imaging system 210. In some non-limiting embodiments, the commands may be based on data received from multiple data sources 104, the data may include injection protocol data, healthcare data, imaging data, and / or any combination thereof.
[0099] As shown in Figure 4, in step 408, process 400 may include generating image analysis results for the image. For example, the protocol management system 102 may generate image analysis results for images of the patient's body based on images of areas of the patient's body generated by the protocol management system 102. In some non-limiting embodiments, the image analysis results may be based on the results of inference by a machine learning model. In some non-limiting embodiments, when generating image analysis results for an image, the protocol management system may provide input to the machine learning model based on a request for inference to the machine learning model and generate output from the machine learning model based on the input. In some non-limiting embodiments, the input may include image-related data such as the image model, image features, the image itself, and / or a combination thereof. In some non-limiting embodiments, the protocol management system 102 may receive image-related data from multiple data sources 104, the multiple data sources may include one or more scanners and / or one or more sensors associated with the medical imaging system 210. In some non-limiting embodiments, the output of the machine learning model may include quantitative data related to the image, such as resolution, clarity, sharpness, brightness, image contrast, signal-to-noise ratio (S / N), level of image blur, and amount of image artifacts. In some non-limiting embodiments, the output may be qualitative.
[0100] As shown in Figure 4, in step 410, process 400 may include determining whether the image analysis result satisfies a threshold image quality. For example, the protocol management system 102 may determine whether the image analysis result satisfies a threshold image quality. In some non-limiting embodiments, the image analysis result may be based on quantitative data related to the image analysis result. In some non-limiting embodiments, determining whether the image analysis result satisfies a threshold image quality may be based on inference of a machine learning model. For example, the protocol management system 102 may provide quantitative data related to the image analysis result of an image as input to a machine learning model and generate an output regarding whether the image analysis result satisfies a threshold image quality. The protocol management system 102 may also provide the threshold itself as input. In some non-limiting embodiments, when determining whether an image analysis result meets a threshold image quality, the output may be binary (e.g., yes, threshold image quality is met, or no, threshold image quality is not met), tertiary (e.g., yes, threshold image quality is met, no, threshold image quality is not met, or the image analysis result is inconclusive regarding whether the threshold image quality is met), or may include multiple determinations, such as specific data points of the image analysis result that meet and / or do not meet the image quality threshold. In some non-limiting embodiments, determining whether an image analysis result meets a threshold image quality may be based on a qualitative output. For example, in some non-limiting embodiments, determining whether an image analysis result meets a threshold image quality may be based on a visual review qualitative output (e.g., manual review of the image by a technician or user).
[0101] In some non-limiting embodiments, if the protocol management system 102 determines that the image analysis results do not meet the image quality threshold, the protocol management system 102 may repeat process 400 or the steps of process 400 to improve the image analysis results. For example, the protocol management system 102 may automatically execute an additional injection protocol, generate additional image analysis results of images of the patient's body, and determine whether the additional image analysis results meet the threshold image quality.
[0102] In some non-limiting embodiments, if the protocol management system 102 determines that the image analysis results do not meet the image quality threshold, the protocol management system 102 can automatically execute an additional injection protocol for the additional injection procedure based on determining the dose of medical fluid to be administered during the additional injection procedure and selecting a specific dose of contrast fluid from multiple doses of contrast fluid, and the injection protocol may include a specific dose. In some non-limiting embodiments, the protocol management system 102 can automatically execute an additional injection protocol for the additional injection procedure based on determining that a partial dose of contrast fluid is to be administered during the additional injection procedure and selecting a specific partial dose of contrast fluid from multiple doses of contrast fluid, and the additional injection protocol may include a specific partial dose. In some non-limiting embodiments, the protocol management system 102 can automatically execute an injection protocol for the additional injection procedure based on determining that a standard dose of contrast fluid is to be administered during the additional injection procedure and selecting a specific standard dose of contrast fluid from multiple doses of contrast fluid, and the additional injection protocol may include a specific standard dose. In some non-limiting embodiments, the protocol management system 102 may determine that a partial dose of contrast fluid is administered during an additional injection procedure to improve the image analysis results, and may select a specific partial dose from a plurality of partial doses to improve the image analysis results. In some non-limiting embodiments, the protocol management system 102 may determine that a standard dose of contrast fluid is administered during an additional injection procedure to improve the image analysis results, and may select a specific standard dose of contrast fluid from a plurality of partial doses to improve the image analysis results.
[0103] For example, after image analysis results generated according to the execution of an injection protocol for an injection procedure in which a standard dose of contrast fluid is administered, the protocol management system 102 may determine that another standard dose of contrast fluid is administered during an additional injection procedure to improve the image analysis results, or that a partial dose of contrast fluid is administered during an additional injection procedure to improve the image analysis results. The protocol management system 102 may further determine a specific dose of contrast fluid to be administered during the additional injection procedure. In some non-limiting embodiments, after image analysis results generated according to the execution of an injection protocol for an injection procedure in which a partial dose of contrast fluid is administered, the protocol management system 102 may determine that another partial dose of contrast fluid is administered during an additional injection procedure to improve the image analysis results, or that a standard dose of contrast fluid is administered during an additional injection procedure to improve the image analysis results, and the protocol management system 102 may further determine a specific dose of contrast fluid to be administered during the additional injection procedure.
[0104] In some non-limiting embodiments, the protocol management system 102 may then generate additional image analysis results of images of areas of the patient's body. In some non-limiting embodiments, generating additional image analysis may include generating additional images of areas of the patient's body according to step 406 of process 400, as described herein.
[0105] In some non-limiting embodiments, the protocol management system 102 can generate additional image analysis results for images of patient body regions without acquiring additional images. For example, the protocol management system 102 can generate an initial image, generate an initial image analysis result for the image, determine if the image analysis result does not meet the threshold image quality, execute an additional injection protocol for the injection procedure, generate a enhanced image of the patient body region (e.g., enhanced initial image), generate an image analysis result, and determine whether the image analysis result meets the threshold image quality before acquiring the image.
[0106] In some non-limiting embodiments, the protocol management system 102 may then generate additional image analysis results of the image according to step 408 of process 400, as described herein. In some non-limiting embodiments, the protocol management system may then determine whether the additional image analysis results meet the threshold image quality. In some non-limiting embodiments, if the protocol management system 102 determines that the image analysis results do not meet the image quality threshold, the protocol management system 102 may repeat process 400 or the steps of process 400 to improve the image analysis results.
[0107] Referring here to Figures 5 to 18, Figures 5 to 18 are schematic diagrams of non-limiting embodiments of a fluid injector 500 for use with a fluid infusion system (e.g., fluid infusion system 108, fluid infusion system 208) and various components thereof, according to aspects of the present disclosure. In some non-limiting embodiments, a fluid infusion system for providing a medical treatment plan may include a fluid injector 500, as shown in Figures 5 to 8.
[0108] Continuing with reference to Figures 5 to 8, Figures 5 to 8 show exemplary embodiments of a fluid injector 500 for use with a fluid injection system. In some non-limiting embodiments, the fluid injector 500 may include at least one fluid injection pump 522, at least one fluid source 524, and a first tube set 526 having at least one valve assembly 528. In some non-limiting embodiments, at least one valve assembly 528 may be configured to selectively provide a fluid connection between at least one fluid source 524 and the first tube set 526, between the first tube set 526 and at least one fluid injection pump 522, or between at least one fluid source 524, the first tube set 526, and at least one fluid injection pump 522.
[0109] As shown in Figures 5 to 8, the fluid injector 500 may include one or more fluid injection pumps 522 (which may be individually referred to as fluid injection pumps 522a, 522b, 522c, 522d, etc.) (e.g., syringe-based pumps, peristaltic pumps, gear pumps) and one or more fluid sources 524 (which may be individually referred to as fluid sources 524a, 524b, 524c, 524d, etc.) (e.g., at least one vial, bottle, bag, container). Figure 5 shows a total of five fluid injection pumps 522 and five fluid sources 524. However, it should be understood that any number of fluid injection pumps 522 and any number of fluid sources 524 may be used and controlled by an injection system (e.g., fluid injection system 108) and / or a protocol management system (e.g., protocol management system 102).
[0110] Continuing to refer to Figures 5 to 8, the first tube set 526 may include a connector member 530 (e.g., a fluid path element) configured to connect to the second tube set 532, and the second tube set 532 may connect to a catheter 534 configured to be fluidly connected to patient P. In some non-limiting embodiments, at least one valve assembly 528 may be configured to selectively provide a fluid connection between the first tube set 526 and the second tube set 532.
[0111] In some non-limiting embodiments, each fluid injection pump 522 (e.g., a syringe-based pump) may include a reservoir 536 (e.g., reservoirs 536a, 536b, 536c, 536d, 536e), a plunger 538 (e.g., plungers 538a, 538b, 538c, 538d, 538e), and a drive member 540 (e.g., pistons such as drive members 540a, 540b, 540c, 540d, 540e). In some non-limiting embodiments, a fluid injection pump 522a (e.g., a peristaltic pump, a gear pump) may include a tube, a rotating member, and a drive member. In some non-limiting embodiments, the fluid injector 500 may further include one or more actuators 544 configured to actuate (e.g., give movement to) the drive member 540 of the fluid injection pump 522. In some non-limiting embodiments, one or more of the fluid injection pumps 522 may include partial-dose fluid injection components and standard-dose fluid injection components. For example, in some non-limiting embodiments, any of the fluid injection pumps 522 may include a partial-dose fluid injection component that can include a partial-dose fluid injection pump. For example, in some non-limiting embodiments, any of the fluid injection pumps 522 may include one or more exemplary partial-dose fluid injection components described herein with respect to Figures 9 to 18, as well as any of those disclosed in International Patent Application PCT / US2024 / 022782, filed on April 3, 2024, the disclosure of which is incorporated herein by reference in its entirety.
[0112] In some non-limiting embodiments, the fluid injector 500 may further include one or more sensors 542 (which may be individually referred to as fluid injection pumps 542a, 542b, 542c, 542d, etc.). For example, one or more sensors 542 may include flow sensors, air sensors, concentration sensors, or other useful sensors. One or more sensors may be placed at various locations and positions on the first tube set 526 to provide data as input to the protocol management system 102.
[0113] In some non-limiting embodiments, the first tube set 526 may be a reusable set such that the first tube set 526 maintains sterility and is suitable for multiple infusion procedures to multiple patients without contaminating its reusable components. In some non-limiting embodiments, the reusable aspect of the system can be prepared for use by assembling a fluid pathway that includes the first tube set 526, a second tube set 532, and a fluid source 524, and by exhausting the air from the fluid pathway elements. The MEDRAD® Centargo CT infusion system offered by Bayer HealthCare LLC is a similar system. As shown in Figure 5, the valve assembly 528 of the first tube set 526 may include one or more valves 528a, 528b, 528c, 528d, etc., at various locations and positions on the first tube set 526 to provide fluid connections between various components of the fluid pathway. As further shown in Figure 5, a catheter 534 (e.g., patient IV) is connected to a fluid infusion unit 500 using a connecting member 530. In some non-limiting embodiments, the fluid injector 500 may also include a waste container W for containing the flushing agent and / or contrast fluid and / or unused flushing agent and / or contrast fluid discharged during priming.
[0114] Based on the intended study, information or data (e.g., patient details such as weight, height, condition, medication, allergies, and details of the infusion protocol) can be received by the protocol management system 102 as described herein, and the protocol management system 102 can provide a medical treatment plan and / or perform the infusion treatment. In some non-limiting embodiments, the protocol management system 102 and / or other systems described herein (e.g., fluid infusion system 108, medical imaging system 110) may be programmed by the operator, the operator may be offered programs for their confirmation, or the programs may be set and the operator may be allowed to confirm and modify the programs as needed.
[0115] In the exemplary system shown in Figure 5, the fluid infusion pumps 522a, 522b, and 522c may be syringes of similar size having, for example, a maximum deliverable volume of about 194 ml, and therefore may have similar performance characteristics. The fluid source 524a may include a flushing solution, such as saline, used to prime the fluid pathway elements, flush other drugs from the fluid pathway elements into the patient, move the drugs through the patient's peripheral circulation to its central circulation, and at that point the drugs are carried forward by the central circulation.
[0116] In some non-limiting embodiments, fluid sources 524a and 524b may contain contrast fluids. This exemplary configuration can provide the ability to inject a total volume greater than the total volume that one fluid infusion pump 522 (e.g., syringe) can hold, or the ability to deliver the entire dose even if one fluid source 524 is empty and has not yet been replaced, so that one of the fluid infusion pumps 522 has less fluid than is needed to administer the entire dose. In some non-limiting embodiments, the fluid sources 524 may contain different contrast fluids.
[0117] In some non-limiting embodiments, the fluid injector 500 may include only two fluid infusion pumps 522a, 522b, similar to the MEDRAD® MRXperion MR infusion system provided by Bayer HealthCare LLC, which uses only two fluid infusion pumps 522. In some examples, fluid infusion pump 522a may be used for flushing and may have a nominal volume of 110 ml. In some non-limiting embodiments, fluid infusion pump 522b may be used to administer contrast fluid and may have a nominal volume of about 65 ml. In some non-limiting embodiments, if the fluid injector 500 includes only one fluid infusion pump 522b for administering contrast agent, and the contrast fluid runs out from the fluid source 524b before the fluid infusion pump 522b is filled, the user may intervene to change the fluid source in order to continue the procedure. Additional fluid infusion pumps 522 may be used to infuse additional drugs (e.g., cardiac stressors for cardiac imaging).
[0118] In some non-limiting embodiments, the fluid injector 500 may utilize two fluid injection pumps 522 having syringes that deliver the same fluid but have significantly different cross-sectional areas, for example, five or ten times or more.
[0119] In some non-limiting embodiments, the fluid injection pump 522b may have a syringe with a nominal volume of 65 ml, as in the MRXperion, and the fluid injection pump 522c may have a reservoir 536c with a volume of 5 ml or 3 ml. In such exemplary embodiments, the fluid injection pump 522b can be used to deliver a volume greater than the capacity of the reservoir 536b of the fluid injection pump 522c, and the fluid injection pump 522c can be used to deliver a volume within its capacity.
[0120] The fluid infusion pump 522a is used to deliver the flushing fluid and may therefore use a larger syringe, such as a nominal 110 ml syringe. The required volume and flow rate of the flushing fluid generally do not change even if the volume of contrast agent or drug being delivered varies over a wide range, because a sufficient flow is needed to move the drug through the tube and the patient's vein within a reasonable timeframe, and a sufficient flush volume is needed to completely flush the line to the patient after the drug flow has stopped.
[0121] Referring now to Figure 6, which shows a non-limiting embodiment of the simplified fluid injector 500 functioning as described above, with a fluid injection pump 522b that can accommodate a larger syringe and a fluid injection pump 522c that can accommodate a smaller syringe, both connected to the same fluid source 524b containing the contrast fluid. This exemplary configuration accommodates the required range of fluid delivery.
[0122] Referring here to Figure 7, which shows a non-limiting embodiment of the fluid injector 500, the fluid injection pump 522d may include a partial-dose fluid injection component, which may be provided pre-filled with the same contrast fluid contained in the fluid source 524b. When a partial dose of the contrast fluid is anticipated to be needed, or when it is determined that a partial dose of the contrast fluid is required for a particular study, a small, pre-filled syringe may be included in the fluid injection pump 522d and connected to a fluid pathway line for delivery, depending on the requirements of the determined injection protocol.
[0123] In some non-limiting embodiments, the reservoir 536d of the fluid infusion pump 522d may be filled through valves 528c, 528d, 528h, and 528g with contrast agent from the fluid infusion pump 522b that had been previously drawn from the fluid source 524b. In this operation, valve 528W may be closed to prevent the fluid from flowing to the waste container W or patient P. After filling the fluid infusion pump 522a, the fluid infusion pump 522a may purge the line between the fluid infusion pumps 522b and 522d to the waste container W, thereby preventing the contrast fluid from being delivered to patient P until it is delivered by the fluid infusion pump 522b or 522d.
[0124] Referring here to Figure 8, Figure 8 shows a non-limiting embodiment that avoids the need to flush the line to the waste container W. The valve 528b associated with the fluid injection pump 522a containing the flushing solution may be connected to a connector member 530' and a fluid path element connecting the connector member 530 to the valve 528h of the fluid injection pump 522d. The connector member 530 can then be connected to the catheter 534 and the patient P. Thus, the contrast agent can be delivered from the fluid injection pump 522d by flushing from the fluid injection pump 522a without affecting the line between the valve 528d and the waste valve 528W.
[0125] Referring here to Figures 9 to 18, Figures 9 to 18 show exemplary embodiments of the partial-dose fluid injection component 900 (hereinafter, "partial component 900"). The partial component 900 can be implemented in place of, or in addition to, one or more fluid injectors such as the fluid injector 500 and / or the fluid injection pump 522 in a fluid injection system such as the fluid injection system 108, in order to perform an injection protocol for an injection procedure as described herein. In some non-limiting embodiments, the partial component 900 may include a partial-dose fluid injection pump. In some non-limiting embodiments, the partial component 900 may be a partial-dose fluid injection pump (e.g., a syringe-based pump, a peristaltic pump, a gear pump). In some non-limiting embodiments, the partial component 900 may be a syringe such as a microsyringe.
[0126] Referring here to Figure 9, Figure 9 shows a non-limiting embodiment of a sub-component 900 in which the fluid injection pump 522b can deliver smaller, more precise volumes of contrast fluid to a sub-pump 922, which can be a microsyringe, a small-bore pump, a small-bore cylinder, etc. The movement of the plunger 938 in the sub-pump 922 may be monitored by a camera or other sensor to ensure that it is filled to the precise volume. The contrast fluid may also be delivered by delivering saline, which is a flushing fluid, from the fluid injection pump 522a, which first delivers the contrast agent from the sub-pump 922 and then flows to the patient P. The contrast fluid may also be delivered by saline flushing until the plunger 938 hits the bottom and a pressure spike occurs. The contrast fluid may be pre-filled into the sub-pump 922 by either a manual hand syringe (not shown) or any other fluid injector pump described herein (e.g., fluid injection pump 522).
[0127] Referring here to Figures 10-12, Figures 10-12 show non-limiting embodiments of a sub-component 900 in which a sub-pump 922 (e.g., a smaller diameter fluid injection pump) is effectively housed within a fluid injection pump 522 (e.g., a larger diameter fluid injection pump). The fluid injection pump 522 and the sub-pump 922 may be driven by two independent actuators 544, 594, with the effect that moving a smaller piston or plunger rod results in more precise fluid delivery, and moving a larger plunger delivers a larger volume and / or flow rate.
[0128] Referring here to Figure 13, Figure 13 shows a non-limiting embodiment of a sub-component 900 in which a peristaltic-like mechanism for compressing the tube is used as one of the fluid injector pumps, for example, as a fluid injection pump 522. The tube may be filled with contrast agent from a fluid source 524 using reciprocating fingers 930 in a linear peristaltic motion. When filled with only the outlet pinch valve 934 closed, the fluid in the tube 926 can be isolated from the fluid source by closing the inlet pinch valve 932. To deliver the fluid, the outlet pinch valve 934 is opened and one or more of the fingers 930 of various sizes can be compressed in a controllable manner by varying amounts to deliver a range of required volumes.
[0129] Referring now to Figure 14, Figure 14 shows a non-limiting embodiment of a sub-component 900 in which the fluid injection pump 522 has a small syringe 922 and refills and dispenses the small syringe 922 multiple times during injection.
[0130] Referring now to Figure 15, Figure 15 shows a non-limiting embodiment of a component 900 in which a small syringe 922 accurately delivers a contrast agent into a patient line filled with saline. Once in the line, the injector can deliver the contrast agent and subsequent saline to the patient by dispensing fluid from the fluid infusion pump 522.
[0131] Referring here to Figures 16A to 16C, Figures 16A to 16C show non-limiting embodiments of a sub-component 900 in which a syringe for the manual delivery of a small amount of contrast agent utilizes a finger-shaped stopper 960 to prevent over-delivery by the person performing the injection.
[0132] Referring now to Figure 17, Figure 17 shows a non-limiting embodiment of the sub-component 900 in which saline wash is controlledly directed to flush the contrast agent from a series of small, precise volumes to deliver a desired dose to the patient.
[0133] Referring now to Figure 18, Figure 18 shows a non-limiting embodiment of a sub-component 900 in which the delivery accuracy from the syringe is controlled by a central rod or plunger whose diameter is slightly smaller than the syringe inner diameter (ID), and which can be manufactured using a more precise mechanism than the syringe barrel, such as centerless grinding.
[0134] In some non-limiting embodiments, an in-bore injector, such as the one disclosed in U.S. Patent Application No. 10 / 921,083, filed on 18 August 2004 and granted as U.S. Patent No. 7,632,245, whose entire disclosure is incorporated herein by reference, can be implemented as a component 900 for use with the fluid injector 500. Delivery accuracy can be sufficient by selecting, filling, and positioning a syringe appropriate to the volume to be used for the patient under study. Optionally, the syringe may be pre-filled precisely to the volume to be delivered, and thus its entire volume delivered, after which a saline flush may be performed.
[0135] In additional embodiments, when two or more fluids, such as contrast agents and saline, are delivered simultaneously and their total volumes and flow rates differ significantly from one another, it is beneficial to recognize that current practices for determining, describing, programming, or specifying, testing, verifying, and validating fluid delivery as a percentage of the total flow rate of contrast agent are difficult for users to understand, calculate, consider, and program, as well as difficult for engineers and designers to design, specify, verify, test, and validate. For example, in the case of a small patient with artificial intelligence (AI) applied to a study for image enhancement (e.g., fast image reconstruction using sparse sampling), the total dose of contrast agent may be, for example, 0.4 ml and may need to be delivered over 15 seconds to provide a sufficient enhancement duration for successful image acquisition, resulting in a contrast agent flow rate of 0.0267 ml / s. In some non-limiting embodiments, as disclosed in U.S. Patent Application No. 17 / 177,954, filed on 17 February 2021 and granted as U.S. Patent No. 11,717,605, whose disclosure is incorporated herein by reference in whole, it may be desirable to have a total volumetric flow to the patient at least 1 ml / s for adults so that the fluid moves through the arm to the central circulation at a sufficiently consistent rate. This injection may be followed by, for example, a 30 ml saline flush at 1 ml / s. Thus, in this example, the contrast agent percentage is 2.67%. This small ratio between the contrast agent volume and the injection volume and flow rate also affects how the flow rate and volumetric accuracy can be most usefully designed, specified, verified, tested, and / or validated. Injectors generally specify accuracy as a fixed value plus a programmed percentage of the total volume or flow rate. However, if only 2.67% contrast agent is injected, and it is desirable that the flow rate and volume of the contrast agent be accurate with a 10% precision, then when the contrast agent is programmed as a percentage of the total fluid, the precision of the total fluid, which is mainly controlled by the precision of the flash fluid, needs to be accurate with a precision of approximately 0.267% ((10% * 0.0267 ml / S) / 1 ml / S).
[0136] In some non-limiting embodiments, the flow rates or volumes of two or more fluids injected together over a given duration may be programmed or specified individually, separately, or independently, in identical or compatible units. In this example, the injection may be programmed to inject a 0.4 ml contrast agent volume for 15 seconds and simultaneously flush with 15 ml of saline for the same duration, or to inject a 4 ml contrast agent volume at a flow rate of 0.0267 ml / S and flush with 15 ml at 0.9733 ml / S, or the contrast agent may be programmed to flush with 0.9733 ml / S for 15 seconds at a flow rate of 0.0267 ml / S for a duration of 15 seconds, where, for a constant flow, the flow rate is equal to the volume divided by the duration.
[0137] In some non-limiting embodiments, in the injector specification, design, verification, testing, validation, and / or approval processes for devices, systems, associated components, and methods for delivering precise and / or small amounts of contrast agent and / or standard amounts of contrast agent and / or saline, the precision of each fluid and / or flow rate may be specified as precision relating to the individual flow rate or volume, rather than the total or net flow rate or volume of the combined flow. In some non-limiting examples, as discussed herein, the contrast agent volume may be specified as a volume of 0.4 ml + / - 10% and a flow rate of 0.0267 ml / s + / - 10%, and the saline flush may be specified as a volume of 15 ml + / - 10% and a flow rate of 1 ml / s + / - 10%. The contrast agent may be injected into the flushing fluid flow, in which case, for example, if the flushing fluid mistakenly flows to a higher level, the total fluid will be more diluted than if the flash had been delivered accurately at the programmed flash flow rate. However, the amount of contrast agent entering the patient's body over time may only be affected by the error in the contrast agent flow rate. This is because a higher flushing fluid volume results in a greater total fluid movement per unit time, but a lower concentration of contrast agent. Consequently, under a first-order approximation, the amount of contrast agent entering the patient per unit time may not be affected by the error in the flash flow rate. In some non-limiting examples, the contrast agent flow rate may be + / - 5%, while the flash flow rate may be + / - 20%. In practice, the consistency of the flash flow rate may be more important than the precision of the flash flow rate. The precise specification and specified percentage of precision depend on several factors, such as what is possible, what is required by regulatory bodies, and factors affecting image quality. In some non-limiting embodiments, it may also be useful to specify the precision (or variability) and absolute precision of the injection.
[0138] In the above example, the contrast agent and injection duration are described as the same, with a dual-flow phase followed by a saline-only flush phase. However, in some non-limiting embodiments, the injection can be described or programmed as a single, longer saline phase with a shorter contrast agent phase that may start after some delay and end before the end of the saline phase. This type of injection is shown in Figure 5A of U.S. Patent Application No. 17 / 606,532, filed 2 June 2020 and published as U.S. Patent Application Publication No. 2022 / 0133982A1, whose disclosure is incorporated herein by reference in its entirety. If the flow rate of the contrast agent is significantly smaller than the flow rate of saline, for example less than 10%, the flow rate of saline may optionally remain constant, with only the contrast agent flow being added.
[0139] Several examples of devices, systems, associated components, and methods for delivering precise and / or small amounts of contrast agent and / or standard amounts of contrast agent to enhance images during medical imaging procedures are shown in the accompanying figures and described in detail above, but other embodiments will be obvious to those skilled in the art and can be easily created without departing from the scope and spirit of the disclosure. Therefore, the foregoing description is intended to be illustrative rather than restrictive.

For example, this disclosure is intended to allow, wherever possible, one or more features of any embodiment or aspect to be combined with one or more features of any other embodiment or aspect.
