Find the tmr for a 6.2cm field size at a depth of 8cm

To find the Tissue Maximum Ratio (TMR) for a specific field size and depth, we usually need data specific to the radiation beam, such as energy (e.g., 6 MV, 10 MV), and the type of machine being used (e.g., LINAC). TMR tables are typically provided by the manufacturer or derived from measurements for a specific beam.

### Given Information:
- Field Size: 6.2 cm
- Depth: 8 cm

### To proceed, you would generally:
1. **Identify the beam energy.**
2. **Consult TMR tables**: Look up the TMR value for a 6.2 cm field size at an 8 cm depth for the corresponding energy.

### Assuming you do not have the TMR table:
You would have to interpolate or find the exact TMR from the data. If we assume a typical energy like 6 MV, the TMR could be in the range of 0.75 to 0.8 for small field sizes. 

Without specific data, I can't provide the exact TMR. You should consult the specific TMR table associated with your equipment.

Would you like a detailed explanation on how to interpolate TMR values or more about radiation therapy physics?

### Follow-up Questions:
1. What is the beam energy you're working with?
2. Do you have access to TMR tables for your specific equipment?
3. Would you like to learn about how TMR varies with depth and field size?
4. Are you looking for a theoretical or practical calculation method?
5. Is there a specific clinical context you’re applying this to?

### Tip:
Always ensure to use the exact TMR data specific to your equipment and calibration setup for accurate dose calculations in radiation therapy.
