MIM Maestro


Reg Reveal & Reg Refine

To ensure the efficacy of deformable registration, MIM Software has introduced Reg Reveal™, the first and only environment for deformable registration quality assurance and reporting.

Reg Refine™ takes deformable registration a major step forward by allowing clinicians to not only detect any areas where a deformation is less than optimal, but to correct them. The unique ability to repeatedly perform deformable evaluation and correction has fundamentally changed how deformable registration can be implemented for critical tasks such as dose accumulation or diagnostic image registration to planning CTs.

Now, virtually any pair of images can be registered to one another, and you can have confidence in the accuracy of the results – for every patient. For example, registering HDR planning CTs that contain an applicator to EBRT CTs for dose accumulation can be done with impressive accuracy. With Reg Reveal and Reg Refine, now even the most challenging of image registration tasks can be accomplished.


MR/CT Deformable

Accurate multi-modality deformable registration is not an easy problem to solve. Before the introduction of Reg Reveal, an even more challenging dilemma was knowing when it worked and when it didn’t.

Now, with Reg Reveal and Reg Refine, we’ve provided a platform where you can be confident in the accuracy of MR to planning CT deformable registration.


ART Assist

ART Assist™ is MIM’s fully customizable, automated processing and reporting tool designed to automatically quantify changes to a patient over the course of radiation delivery.

Previously, the process for determining when and whether to adapt a patient’s plan was limited by the time required to generate relevant quantitative information based on daily imaging.

Now, changes in critical structures and dose constraints can be tracked over the course of treatment, compared to the original plan, and plotted in automatically generated reports. ART Assist makes true dose-guided adaptive radiation therapy possible.


GTV Contouring

Accurate target volume definition often requires the integration of multi-modality images. MIM Software™, which began as an image fusion company almost a decade ago, has developed unparalleled tools for the integration of diagnostic images into treatment plans.

With Assisted Alignment, our mutual information rigid alignment algorithm, MIM® generates accurate fusions, typically in fewer than ten seconds. Multiple modalities can be fused simultaneously, and contours can be edited dynamically from any plane and on any modality – whatever image best visualizes the tumor.

Integrating PET/CT into treatment plans presents a series of challenges. Scans are typically done in a non-treatment position and on a curved couch. Additionally, defining a PET GTV can be difficult due to the subjective nature of visual delineation and the many limitations of the common SUV threshold tools. MIM provides tools to address these problems resulting in greater confidence for incorporating PET/CT into treatment plans.

The VoxAlign Deformation Engine™ accurately registers PET/CT images to simulation CTs by correcting for changes in positioning. PET Edge, MIM’s gradient-based segmentation technique, accurately defines PET positive GTVs, helping to take the guesswork out of PET contouring.


Auto-Contouring

MIM Software Inc. has consistently led the industry with auto-contouring tools for the past several years. MIM Maestro™ was one of the first commercial software solutions with atlas-based segmentation. And with user-defined atlas libraries, automatic atlas subject selection, and the VoxAlign™ algorithm, it’s still the best solution on the market.

Contour CoPilot™ (Patent Pending) is the latest milestone in our history of innovation, providing an auto-contouring solution for both CT and MR. Instead of pre-contouring an entire structure that you must then adjust slice by slice, Contour CoPilot fits right into the editing workflow, where it saves you time along the way and learns from your edits.

Experience the fastest way to contour on any plane, on any modality, and with any contour.

"The Contour CoPilot tool is amazing. I love using the CoPilot to rapidly create contours. We are building new standardized multi-site contouring atlases, and we are using the CoPilot instead of other segmentation tools. Compared to other various options, the CoPilot saves a lot more time and has superior ergonomic properties.

4D CT

4D CT contains much more information than most centers are able to take advantage of due to time constraints and limited functionality in other software. MIM unlocks the full benefit that 4D CT imaging offers.

In addition to contouring and dose review on the 4D cine and MIP images, MIM also allows you to contour a single phase and use the VoxAlign Deformation Engine to automatically propagate the contours to all the other phases.

Deformable propagation of an entire structure set takes just a few minutes and generates an ITV for planning and an entire structure set for 4D DVH evaluation. You can generate a DVH for each phase to help determine if gated treatment is necessary, or even perform 4D dose accumulation to better evaluate the overall dose delivered.

With these advanced tools, RT-PACS archival, and compressed transfer, MIM will help you get the most out of your 4D CTs with little more effort than a traditional 3D simulation.

Contour CoPilot™

In 2008, when we introduced atlas-based segmentation and adaptive re-contouring into the clinical setting, MIM became a pioneer in 3D auto-contouring.

Even a few years later, these and other auto-contouring tools are still enormous timesavers. But ultimately, every automatically generated contour is reviewed and, if needed, edited slice by slice. Because of this limitation, we recognized the need for an alternate method to generate contours quickly, regardless of anatomy, on both CT and MR. To meet this need, we designed a tool which is revolutionizing manual contouring – Contour CoPilot.

Contour CoPilot uses our flexible and accurate VoxAlign Deformation Engine to “learn from” the work you’ve done on a contour slice and propagate that contour to the next slice, using the underlying images to find and adjust to the differences in the volume. Contour CoPilot uses the slice you just contoured to auto-contour the slice you were going to review and edit next – seamlessly fitting into your existing contouring workflow.


Adaptive Therapy

Deciding when to replan a patient can be a challenge without sophisticated quantitative tools.

Using MIM, contours can be automatically deformed from a planning CT to a CBCT. Then DVH and isodose curves can be compared against the original treatment plan, or even summed for an overall picture of delivered dose. Then, when replanning is required, documentation to justify the planning decision is readily available.

Many institutions have experienced an immediate increase – three times or more – in the number of patients undergoing adaptive replanning as a direct result of implementing MIM into their workflow.

Quite simply, by removing the bottleneck of contouring mid-treatment CTs, physicians feel much more equipped to provide this valuable correction step to patients. Typically, auto-contours are ready in about a minute and only take a few minutes to review and edit.

"MIM has made adaptive replanning of head and neck IMRT cases a feasible standard operating procedure in our department. MIM has decreased physician turnaround of approved volumes by a significant amount."

Dose Evaluation

With unlimited access to MIM throughout your department, you can review and compare plans from your office, home, or even patient consult rooms and tumor boards.

If a patient has received radiation previously, MIM can quickly sum as many dose volumes as required, giving a clearer picture of the overall dose the patient will receive. Even multi-modality treatments, such as SRS or brachytherapy and EBRT, can be combined after conversion into biologically effective dose. A dose volume deformed using the VoxAlign Deformation Engine can be sent to the planning system as a baseline dose for optimization, or isodose curves can be turned into contours to be used as tuning structures to reduce hot spots.

Correlating delivered dose with post-treatment response assessment images can be critical for patient management. Without MIM, it can be extremely difficult or even impossible to determine how disease seen on a PET/CT or MR taken months after treatment relates to the treatment the patient received. With MIM, this evaluation can be done with remarkable accuracy and ease.

VoxAlign Deformation Engine™

The VoxAlign Deformation Engine, introduced in 2007, includes the first commercially available deformable registration algorithm tuned for CT-CT registration.

Even today, most other systems use general-purpose deformable registration algorithms, similar to those that are available with open source toolkits like ITK. By focusing specifically on CT to CT registration, we were able to develop an algorithm which harnesses more information from the images to guide the registration to a more accurate result.

Our algorithm is a constrained, intensity-based, free-form deformable registration. Our implementation uses the entire contrast window of the CT for matching the two scans, instead of a mutual information approach which compresses the contrast in the CT, and leaves less information to guide tissue matching. Additionally, our algorithm employs millions of degrees of freedom for the registration, allowing it to accurately capture very local deformations in addition to global changes. Finally, the algorithm is constrained in an attempt to minimize unexpected deformations in the final result, such as bone deformation or registrations which aren’t smooth or tear tissue.

While most algorithms with this level of accuracy would require hours to execute, our implementation typically takes under a minute.

Vendor Neutrality

With MIM as the hub and front end for the entire department workflow, physicians only need to learn one software program for many of their tasks.

Contouring, fusion, dose review, and much more can be done in MIM regardless of the treatment planning and other systems you use. From radiology PACS to outside CDs to treatment planning systems, MIM integrates seamlessly with all the systems in your workflow.

Most treatment planning systems currently support DICOM RT structure import and RTplan and RTdose output. As a result, you can use MIM’s best in class tools to store, visualize, and manipulate this rapidly increasing amount of data – no matter where it’s coming from or needs to go. There is no need to recommission old linacs with new software. Just export all your DICOM data to MIM, knowing that no matter how you upgrade your systems, your data will be ready when you need it.

Data Management

The MIM Maestro Unlimited™ Department Solution is designed to get data to where it needs to be, when it needs to be there.

MIMpacs RT™, included in the Department Solution, provides tools such as automatic querying for diagnostic images, automatic syncing to MIMcloud™, and compressed data transfer to ensure fast access to the data you need.

No longer are you restricted to working on one patient at a time. With multiple sessions, you can preload one patient to review with a colleague while you work on another. Also, multiple people can contour the same patient at the same time and simply merge their results when finished.

With MIM, the treatment planning system is no longer a bottleneck. The TPS can be used for what it’s best at – plan optimization and dose calculation – while MIM handles the rest.

PET Edge™

In response to the many difficulties with PET segmentation when using visual delineation or SUV threshold tools, we developed PET Edge, an innovative gradient-based segmentation method.

Visual tumor delineation is limited by the user’s selected image contrast and level of expertise with PET, as well as variability between users. SUV threshold tools are subject to a number of limiting factors, including the tumor uptake relative to the background, heterogeneous uptake within the tumor (e.g., areas of necrosis), tumor size, and partial volume effects. PET Edge avoids all of these pitfalls by robustly identifying the boundary between tumor and background using the maximum change in SUV value

PET Edge has been shown to outperform SUV threshold tools across multiple PET cameras, reconstruction methods, tumor sizes, and levels of background activity. Using realistic digital PET phantoms with lung tumors of varying size, shape, and location, PET Edge was found to be more accurate and consistent between users than both visual tumor delineation and SUV thresholds. Recent pathology studies have also demonstrated the superior accuracy of PET Edge over SUV thresholds.

PET Edge is the tool radiation oncologists have been waiting for to truly experience the full value of functional imaging in their treatment plans.


The Assistant

Working from within MIMpacs RT, The Assistant provides an integrated control for automating series management.

The Assistant Manager screen shows you in simple terms what automatic processing is scheduled and what has already occurred. Simple-to-use filters automatically direct actions by referencing DICOM tags. Easy-to-write rules can be time-based or event-based to handle all incoming series. This gives you the flexibility to routinely control actions by any specific day and time or to automatically respond to incoming series.

The Assistant interfaces directly with MIM Workflows allowing you to process multiple series automatically. For example, atlas-based segmentation can be automated for all patients, so contours are ready for review the moment you sit down. Thanks to The Assistant, contours can be ready in advance, saving time and effort.


Long-term Storage

MIMcloud provides a hassle-free, secure, and surprisingly economical solution for long-term storage of your patient data. Since MIM is committed to IHE-RO conformance, you can rest assured that your DICOM RT objects and other data will be easily accessible for as long as you need.
