# Industrial Specification: Isocenter Verification System

## 1. Technical Definition
A precision measurement system that verifies the alignment and stability of the radiation isocenter in a Linear Accelerator (LINAC) gantry.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.1-2.0 mm positional accuracy at 1.0 m SAD (Source-to-Axis Distance)**. Failure boundary: **&gt;2.0 mm positional deviation from true isocenter at 1.0 m SAD**, Mechanism: **Thermal expansion of gantry structural components exceeding 0.02 mm/°C coefficient, combined with bearing wear creating &gt;0.05 mm radial play in rotation mechanism**.

### 2.1 Analytical Physics Model
Governed by the **Rayleigh Resolution Criterion**:

> **Primary Equation**: $d = \frac{0.61 \lambda}{NA}$  
> **Engineering Impact**: Defines the theoretical limit of machine vision systems.
