High-intensity focused ultrasound (HIFU) provides a potentially non-invasive alternative to conventional therapies. We have been using the extracorporeal ultrasound-guided Model-JC Tumor Therapy System (HAIFU (TM) Technology Co, China) in clinical trials to evaluate the safety and feasibility of treating renal and liver tumours. 30 patients have been treated (22 liver and 8 kidney tumours), all of whom were available for adverse event reporting. Of the 22 liver tumours, 20 are evaluable for response to treatment; 14 were followed up with magnetic resonance imaging (MRI) alone, and 6 with both MRI and histological resection. Evidence of ablation was seen in 20/20 (100%) cases radiologically, and 6/6 (100%) cases histologically. Of the 8 kidney tumours treated, 7 are evaluable; 2 were followed up with MRI alone, and 5 with both MRI and histological resection. Evidence of ablation was seen in 4/7 (57%) radiologically and 1/5 (20%) histologically. Mild, moderate or severe transient pain was reported by 16 (53%), 7 (23%) and 1 (3%) patients, respectively. Superficial skin toxicity was seen in 7 patients (23%). Renal function was unaffected, and all patients were fit for discharge from hospital the day after treatment. Early results show that this technique is feasible, and carries a low morbidity.

High‐intensity focused ultrasound (HIFU) when used clinically to treat liver and kidney tumours is often directed between the ribs. This paper details the construction of a tissue phantom, incorporating ribs, and its use to assess the clinical safety of HIFU exposures. The prefocal, acoustic side‐lobes of the ultrasonic beam were studied with and without rib interference, and thermocouples used to assess in‐situ temperature changes. The results show that there are implications in regards to the safety of clinical treatment, should the operator be unaware of the characteristics of the transducer being used.

Summary Objective To propose a standard for the conduct of visually directed trans-rectal high intensity focused ultrasound (HIFU) and to offer a formal description of the changes seen on B-mode imaging during this procedure. We describe our early experience of using two different treatment methods; algorithm based, 'low power' HIFU and visually directed 'high power' HIFU for the treatment of organ confined prostate cancer.
