Artemis along with the Needle Guide Attachment is used for image-guided interventional and diagnostic procedures of the prostate gland. It provides 2D and 3D visualization of Ultrasound (US) images and the ability to fuse and register these images with those from other imaging modalities such as Ultrasound, Magnetic Resonance, Computed Tomography, etc. It also provides the ability to display a simulated image of a tracked insertion tool such as a biopsy needle, guidewire or probe on a computer monitor screen that shows images of the target organ and the projected future path of the interventional instrument taking into account patient movement. The software also provides a virtual grid on the live ultrasound for performing systematic sampling of the target organ. Other software features include patient data management, multi-planar reconstruction, segmentation, image measurements, 2D/3D image registration, reporting, and pathology management. Artemis is intended for treatment planning and guidance for clinical, interventional and/or diagnostic procedures. The device is intended to be used in interventional and diagnostic procedures in a clinical setting. Example procedures include, but are not limited to image fusion for diagnostic clinical examinations and procedures, soft tissue ablations and placement of fiducial markers. Artemis is also intended to be used for patients in active surveillance to keep track of previous procedures information and outcomes. Artemis Cryo Treatment Planning module is an add on to the existing Artemis software that allows physicians to prepare for cryo treatment planning based on positive pathology cores obtained during Artemis guided biopsies and registration results with other imaging modalities such as MRI, CT. The module allows accurate placement of cryo probes on targets, 3D tracking, real-time feedback on extend of cryo ice formation. The technology provided by Artemis generates ice models based on the specifications provided by the cryo device manufacturers and displays the models on the live ultrasound to provide guidance to the users during the procedure. The module also allows outlining or segmenting other organs that surround the prostate. Organs include bladder and urethra.

Artemis is designed to display the 2-D live video received from commercially available ultrasound machines and use this 2-D video to reconstruct a 3-D ultrasound image. The system has been designed to work with the clinicians' existing ultrasound machine, probe, commercially available biopsy needle guide, needle gun combination, and cryoablation systems. Additional software features include patient data management, multi-planar reconstruction, segmentation, image measurement, reporting and 3-D image registration. Artemis is comprised of a mechanical assembly that holds the ultrasound probe and tracks probe position. The mechanical tracker is connected to a PC-based workstation containing a video digitizing card and running the image processing software. Control of the ultrasound probe and ultrasound system is done manually by the physician, just as it would be in the absence of Artemis. However, by tracking the position and orientation of the ultrasound probe while capturing the video image, the workstation is able to reconstruct and display a 3-D image and 3-D rendered surface model of the prostate. The reconstructed 3-D image can be further processed to perform various measurements including volume estimation, which can be examined for abnormalities by a physician. Patient information, notes, and images may be stored for future retrieval, and locations for biopsies may be selected by the physician. The system also allows previously acquired 3-D models to be recalled, aligned, or registered to the current 3-D model of the prostate, which is especially useful for patients under active surveillance. The physician may attach a commercially available biopsy needle guide compatible to the ultrasound probe and use the probe and needle to perform tissue biopsy and or cryoablation. Whenever the ultrasound machine is turned on by the physician, the live 2-D ultrasound image is displayed on the screen of Artemis during the procedure. As the ultrasound probe with attached needle guide is maneuvered by the physician, the position and orientation of the probe with respect to the organ is tracked. Artemis is able to add, display and edit loaded plans for the procedure as well as provide the probe position and needle trajectory relative to the 3-D image and 3-D rendered surface model of the prostate. In addition to standard transrectal needle guidance procedures, Artemis also supports transperineal needle guidance by mounting a Needle Guide Attachment (NGA). A commercially available needle guide compatible with the NGA is used. This NGA will be used for both biopsy and cryo needles. The NGA provides additional data to track the needle direction angle. When using transperineal mode, the procedure planning, segmentation, registration and navigation are performed in the same way as the standard transrectal procedure. The only difference lies in how the needle guide needs to be moved to target the different planned locations. For the transrectal procedure, the needle guide is always attached to the probe. Therefore moving the probe moves the needle guide. In transperineal needle guidance procedures the needle is not attached to the probe. Therefore the NGA needs to be moved to move the needle guide. Artemis highlights the closed target to the current needle guide position. Artemis offers the physician additional 3-D information for assessing prostate abnormalities, planning and implementing biopsy procedures. The additional image processing features are generated with minimal changes to previous Ultrasound probe based procedures, and the physician always has access to the live 2-D ultrasound image during prostate assessment or biopsy procedure. The device also provides automated reports with information and pictures from the procedure.

ProFuse CAD is a post-processing software tool intended for viewing, reviewing and reporting imaging files such as Magnetic Resonance Imaging (MR), Computed Tomography (CT) and Positron Emission Tomography (PET) studies. The software is able to process time series modality data acquired before, during, and after a contrast agent has been administered to the patient. The software allows a physician to evaluate tissue characteristics based on contrast enhancement visible on the time series data can also be processed to get subtraction image time -series with any reference time point. ProFuse CAD also provides capability to process a specialized MRI series called diffusion weighted imaging to evaluate tissue characteristics based on water diffusion. Some of the other posts -processing features include multi-planar reformats and registration between images. ProFuse CAD has a marking feature that allows the user to outline organs with minimal input and also annotate regions in the image in 3D. The software also allows for grading the annotated regions as defined by the user. After review, the software automatically generates a patient report that provides information like; organ volume, annotations; and grading along with automatically generated screenshots of the annotations in different images. Planned data from ProFuse CAD can be used for interventional procedures like MR - TRUS fusion biopsies. The data can be displayed on medical device data systems. ProFuse CAD is used as a tool to review and add to the results of interventional procedures like; adding pathology information when reviewing MR-TRUS fusion biopsy. When interpreted by a skilled physician, this device provides information that is intended to be used for screening, analysis, and interventional planning. Patient management decisions should not be made based solely on the results of ProFuse CAD. ProFuse CAD is intended to be used as an image viewer of multi-modality, digital images, including Ultrasound, CT, PET. ProFuse CAD is intended to be used in a variety of setting such as; medical offices, clinics, hospital, and home office.

ProFuse CAD is standalone Computer Aided Detection (CAD) software that is used by radiologists to visualize, analyze, plan and interpret medical images using tools available in the software. Some of the tools in the software are - Visualization: The software allows simultaneous visualization of different images with the ability to view them in different orientations e.g. transverse, sagittal, coronal and 3D. - Organ segmentation: The software allows user to outline the organ of interest (e.g. prostate) - Image annotation: The software allows user to mark regions of interest (ROI) on images - Time-series analysis: The software allows user to view the time-curve plots for a single location or average over a region (ROI). The user could also calculate different parametric maps based on pharmacokinetic modeling. The parametric maps could be viewed as a separate series or be overlaid as color on another series. The software also allows users to calculate subtracting images from a customizable user defined time point. - Diffusion series analysis: Diffusion weighted series is a special type of magnetic resonance imaging (MRI) sequence that measures diffusion of water molecules in the body. A set of different diffusion weighted images are obtained and from the set of images the software allows the user to fit different mathematical models to extract different parametric maps. The parametric maps could be viewed as a separate series or be overlaid as color on another series. - Report: The software allows the user to create reports following either the PIRADS (see definition) standard or a customizable standard. - Export: The software allows the planned images to be exported for different procedures e.g. biopsy, therapy, etc. Information exported by ProFuse CAD could then be used in other software solutions like ProFuse Bx, ProFuse FP. - Review: Review, add and modify data from the 3D visualization software (Artemis). The data includes acquired volume, organ segmentation, planned and recorded biopsy location and pathology information.
