About T1 files

The .t1 extension is a technical homograph used in two completely different industries: medical imaging and digital typography.

1. GE Medical MRI Raw Data (Primary Use):
Most commonly, a .t1 file is a raw Magnetic Resonance Image generated by GE HealthCare scanners. These files specifically capture T1-weighted longitudinal relaxation data, which is critical for visualizing fat and water content in anatomical structures.

The Problem: These are proprietary, high-bit-depth raw dumps. Standard image viewers like Windows Photos or Mac Preview cannot render them. They are useless for patient demonstrations or quick sharing without specialized medical software.
The Solution: For archiving or professional analysis, convert these to DICOM standard. For presentations or quick viewing, convert them to PNG or JPG using convert.guru.

2. PostScript Type 1 Font (Legacy):
In the creative sector, .t1 files are legacy PostScript Type 1 font sources, historically associated with FontLab (formerly Fontographer) or specific Unix/Amiga typesetting systems.

The Problem: This format is effectively dead. Adobe officially ended support for Type 1 fonts in January 2023. Modern software like Photoshop and InDesign will no longer recognize or load these files, triggering "Missing Font" errors in your projects.
The Solution: To save your typography assets, you must convert .t1 fonts to modern OpenType (.OTF) or TrueType (.TTF) formats immediately.

3. Tekla Structures Log:
Less frequently, a .t1 file may be a plain text log generated by Tekla Structures for CNC machine operations.
