  • Allows for decay correction of activity back to time of injection ●
  • Allows for correction of photon attenuation ●
  • . Allows for correction of photon scatter
  • Allows for correction of collimator detector resolution effects ●
  • Allows for camera sensitivity calibration providing output in Becquerels per ml (Bq/ml) .
AI/ML Overview

Here's a breakdown of the acceptance criteria and study details for MIM - SPECTRA Quant based on the provided document:


1. Table of Acceptance Criteria and Reported Device Performance

IsotopeCollimatorAcceptance Criteria (Quantitative Error)Reported Quantitative ErrorVerification Result
Tc99mLEHR<10%<5%Passed
I-123LEHR<10%<5%Passed
I-131HE<10%<5%Passed
Lu-177ME<10%<5%Passed

Note: The acceptance criterion for MIM – SPECTRA Quant is a quantitative error of smaller or equal to 10% in regions that are large enough not to be affected by the partial volume effect.


2. Sample Size Used for the Test Set and Data Provenance

  • Test Set Description: The test set included "standard quality control phantoms, a Liver phantom, and simulated phantoms based on the NEMA IEC Body Phantom." It also involved "clinical data."
  • Sample Size: The exact number of phantoms or clinical cases is not specified in the provided text.
  • Data Provenance: The document does not explicitly state the country of origin for the data or whether it was retrospective or prospective. It only mentions the use of "physical and simulated phantoms as well as with clinical data." It's likely that the phantom data would be generated in-house or sourced from standard organizations.

3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts

  • Number of Experts: "Board certified clinicians" performed "validation testing" and "qualified Nuclear Medicine professionals" rated reconstructions of clinical data. The exact number of clinicians or Nuclear Medicine professionals is not specified.
  • Qualifications: "Board certified clinicians" and "qualified Nuclear Medicine professionals." Specific experience level (e.g., "10 years of experience") is not specified.

4. Adjudication Method for the Test Set

The document states that "All reconstructions of clinical data were rated as acceptable for clinical use by the qualified Nuclear Medicine professionals." This suggests an expert review process. However, a specific adjudication method (like 2+1, 3+1) for resolving disagreements among multiple experts, if multiple were involved, is not described.


5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study was done

  • Was it done? The document mentions "clinicians using MIM – SPECTRA Quant performed validation in comparison to independently implemented, industry-standard solutions." This suggests a comparison. However, it does not explicitly state that a formal Multi-Reader Multi-Case (MRMC) comparative effectiveness study was conducted with a focus on human reader improvement with vs. without AI assistance. The focus described is on the software's performance compared to standard solutions.
  • Effect Size: No effect size or quantification of how much human readers improve with AI vs. without AI assistance is provided.

6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) was done

Yes, a standalone performance evaluation was done. The "Quantitative Accuracy Verification of MIM - SPECTRA Quant" table directly measures the "Quantitative Error" of the software itself (the algorithm) against predefined acceptance criteria using phantoms. This is a direct measure of the algorithm's standalone performance.


7. The Type of Ground Truth Used

The ground truth for the quantitative accuracy assessment (the core of the reported performance data) was established based on the known properties of the phantoms. Phantoms are designed to have known concentrations of radioactive isotopes, which serve as the ground truth for measurement accuracy. For "clinical data," the ground truth of "acceptability for clinical use" was established by "qualified Nuclear Medicine professionals" (expert review).


8. The Sample Size for the Training Set

The document does not provide any information about the sample size used for the training set. This is a key omission for understanding the AI model's development.


9. How the Ground Truth for the Training Set was Established

The document does not provide any information on how ground truth was established for a training set. Given the lack of mention of a training set, it's possible the quantitative accuracy features (decay, attenuation, scatter, resolution corrections) are based on physical models and algorithms rather than a trained machine learning model, or if a model was used, its training details are not disclosed.

Intended Use

MIM software is intended for trained medical professionals including, but not limited to, radiologists, oncologists, physicians, medical technologists, dosimetrists and physicists.

MIM is a medical image and information management system that is intended to receive, transmit, store, retrieve, display, print and process digital medical images, as well as create, display and print reports from those images. The medical modalities of these medical imaging systems include, but are not limited to, CT, MRI, CR, DX, MG, US, SPECT, PET and XA as supported by ACR/NEMA DICOM 3.0.

MIM provides the user with the means to display, register and fuse medical images from multiple modalities. Additionally, it evaluates cardiac left ventricular function and perfusion, including left ventricular end-diastolic volume, end-systolic volume, and ejection fraction.

The Region of Interest (ROI) feature reduces the time necessary for the user to define objects in medical image volumes by providing an initial definition of object contours. The objects include, but are not limited to, tumors and normal tissues.

MIM provides tools to quickly create, transform, and modify contours for applications including, but not limited to, quantitative analysis, aiding adaptive therapy, transferring contours to radiation therapy treatment planning systems and archiving contours for patient follow-up and management.

MIM aids in the assessment of PET/SPECT brain scans. It provides automated quantitative and statistical analysis by automatically registering PET/SPECT brain scans to a standard template and comparing intensity values to a reference database or to other PET/SPECT scans on a voxel by voxel basis, within stereotactic surface projections or standardized regions of interest.

MIM allows the dose distribution of an implant to be individually shaped for each patient and is a general purpose brachytherapy planning system used for prospective and confirmation dose calculations for patients undergoing a course of brachytherapy using permanent implants of various radioisotopes.

For Yttrium-90 (Y90) microspheres, MIM should only be used for the retrospective determination of dose and should not be used to prospectively calculate dose for the case where there is a need for retreatment using Y90 microspheres.

Performance Data

Validation testing with MIM - SPECTRA Quant was performed by board certified clinicians. In all cases, the software passed its performance requirements and met specifications. Additionally, clinicians using MIM – SPECTRA Quant performed validation in comparison to independently implemented, industry-standard solutions. It was demonstrated that MIM software, when used according to operating instructions, can be used safely and effectively.

Furthermore, MIM Software Inc. has conducted performance and integration testing on MIM – SPECTRA Quant software. Standard quality control phantoms, a Liver phantom, and simulated phantoms based on the NEMA IEC Body Phantom were used for verification testing. All tests were performed using standard clinical acquisition and reconstruction protocols.

The accuracy of corrections for attenuation, scatter, and resolution effects were verified in physical and simulated phantoms as well as with clinical data. In all cases, the software passed its performance requirements and met specifications. All reconstructions of clinical data were rated as acceptable for clinical use by the qualified Nuclear Medicine professionals.

The absolute quantitative accuracy of MIM – SPECTRA Quant was verified in physical and simulated phantoms for various isotope-collimator combinations. The acceptance criterion for MIM – SPECTRA Quant is a quantitative error of smaller or equal to 10% in regions that are large enough not to be affected by the partial volume effect. The error in reconstructed activity concentration for these regions was less than 5% which was better than the predefined requirements. In small targets the
