| **Key name** | **Requirement level** | **Data type** | **Description** |
| ------------------------------------ | --------------------- | -------------------------------------- | ------------------------------------------------------------------------------------------------------------------ |
| AcquisitionMode | REQUIRED | [string][] | Type of acquisition of the PET data (for example, `"list mode"`) |
| ImageDecayCorrected | REQUIRED | [boolean][] | Boolean flag specifying whether the image data have been decay-corrected. |
| ImageDecayCorrectionTime | REQUIRED | [number][] | Point in time from which the decay correction was applied with respect to TimeZero in the default unit seconds. |
| ReconMethodName | REQUIRED | [string][] | Reconstruction method or algorithm (for example, `"3d-op-osem"`). |
| ReconMethodParameterLabels | REQUIRED | [array][] of [strings][] | Names of reconstruction parameters (for example, `["subsets", "iterations"]`) |
| ReconMethodParameterUnits | REQUIRED | [array][] of [strings][] | Unit of reconstruction parameters (for example, `["none", "none"]`). |
| ReconMethodParameterValues | REQUIRED | [array][] of [numbers][] | Values of reconstruction parameters (for example, `[21, 3]`) |
| ReconFilterType | REQUIRED | [string][] or [array][] of [strings][] | Type of post-recon smoothing (for example, `["Shepp"]`) |
| ReconFilterSize | REQUIRED | [number][] or [array][] of [numbers][] | Kernel size of post-recon filter (FWHM) in default units `"mm"`. |
| AttenuationCorrection | REQUIRED | [string][] | Short description of the attenuation correction method used. |
| ReconMethodImplementationVersion | RECOMMENDED | [string][] | Identification for the software used, such as name and version. |
| AttenuationCorrectionMethodReference | RECOMMENDED | [string][] | Reference paper for the attenuation correction method used. |

| DecayCorrectionFactor | RECOMMENDED | [array][] of [numbers][] | Decay correction factor for each frame. |
| DoseCalibrationFactor | RECOMMENDED | [number][] | Multiplication factor used to transform raw data (in counts/sec) to meaningful unit (Bq/ml) (dicom tag 0054,1322). |
| PromptRate | RECOMMENDED | [array][] of [numbers][] | Prompt rate for each frame (same units as `Units`, for example, `"Bq/mL"`). |
| RandomRate | RECOMMENDED | [array][] of [numbers][] | Random rate for each frame (same units as `Units`, for example, `"Bq/mL"`). |
| SinglesRate | RECOMMENDED | [array][] of [numbers][] | Singles rate for each frame (same units as `Units`, for example, `"Bq/mL"`). |

All reconstruction-specific parameters that are not specified, but one wants to include, should go into the `ReconMethodParameterValues` field.
