Cryosurgery of the skin is a common treatment for both benign and malignant skin cancers. Monitoring the depth of the frozen lesion during cryosurgery, either by estimation based on the lateral spread of freeze at the skin surface or via thermocouples, may be inaccurate because of the heterogeneous nature of tissue. We describe an integrated cryosurgical probe and magnitude resonance imaging probe which we use to obtain high resolution MR images of skin, subcutaneous muscle and the frozen lesion during cryosurgery.
皮肤冷冻手术是治疗良性和恶性皮肤癌的常见方法。在冷冻手术过程中，通过基于皮肤表面冷冻侧向扩散的估计或通过热电偶来监测冷冻病变的深度，可能会因组织的异质性而不准确。我们描述了一种集成的冷冻手术探头和磁共振成像探头，我们用它在冷冻手术过程中获取皮肤、皮下肌肉和冷冻病变的高分辨率磁共振图像。
